4g tube
8-year durability
Non-conductive
I’ve been using ARCTIC MX-4 for over five years now, and it remains my go-to thermal paste for most mini PC applications. The carbon microparticle formula delivers excellent thermal conductivity without the risks associated with metal-based pastes. What impresses me most is the consistency – every tube performs exactly the same, which I can’t say for some budget alternatives I’ve tested.
The application process is straightforward thanks to the ideal viscosity. It spreads evenly without being too runny or too thick, making it perfect for first-time builders. I’ve applied MX-4 to dozens of mini PCs and consistently see temperature improvements of 15-25°C compared to dried-out stock thermal compound. The 4g tube provides enough material for multiple applications, offering excellent value for money.
What really sets MX-4 apart is its longevity. ARCTIC claims 8 years of durability, and my testing supports this. I have systems running for 3+ years with MX-4 still performing well. The non-conductive formula eliminates the risk of short circuits if you accidentally get some on adjacent components, which is especially important in tight mini PC layouts.
The metal-free composition means it’s completely safe for all applications, including direct-die cooling scenarios where metal particles could cause issues. I’ve used MX-4 on CPUs, GPUs, VRMs, and even chipset heatsinks with consistent results. The grey paste applies cleanly and doesn’t separate or dry out over time like some cheaper alternatives. Similar to how efficient cooling design in audio equipment allows components to run cool even at high volumes, MX-4 maintains stable temperatures under sustained loads.
MX-4 excels in everyday mini PC applications where you need reliable, safe thermal performance. It’s perfect for upgrading office mini PCs, media servers, and light gaming rigs. The non-conductive formula makes it ideal for first-time builders or anyone working in tight spaces where accidental spills are possible. I particularly recommend it for replacing stock thermal paste on brand-new mini PCs, as manufacturer applications are often poorly applied.
Clean the old thermal compound completely with isopropyl alcohol before applying. A pea-sized amount in the center of the CPU/GPU is usually sufficient. The included spreader isn’t necessary – mounting pressure will distribute the paste evenly. For mini PCs with heatspreaders, apply a thin layer to both surfaces for maximum contact. Avoid the “X” pattern or spreading too thin, as MX-4 works best with moderate application thickness.
Premium thermal paste
Extreme conductivity
Long-lasting
When I need maximum cooling performance, Thermal Grizzly Kryonaut is my premium choice. This thermal paste consistently delivers 5-13°C temperature improvements over stock compound, which is significant for thermally constrained mini PCs. The specialized formula achieves extreme thermal conductivity that genuinely makes a difference in demanding applications like gaming, video editing, or scientific computing.
I tested Kryonaut on a heavily-loaded mini PC that was thermal throttling at 95°C. After applying this paste, maximum temperatures dropped to 82°C under the same workload – a 13°C improvement that eliminated throttling entirely. The smooth, even consistency makes application satisfyingly precise, and the included spatula helps spread it perfectly across the die.
The industrial-grade formulation maintains performance even after extended periods at high temperatures. I’ve had systems running Kryonaut for over a year with no degradation in cooling performance. The paste doesn’t pump out or dry out, maintaining consistent thermal transfer over time. However, the thin consistency that makes it easy to apply also means it can migrate from direct-die applications, so I don’t recommend it for GPU mounting or bare-die scenarios.
The 1g tube size is the main drawback. It’s enough for one or two applications, making it expensive if you’re maintaining multiple systems. However, for a single high-performance mini PC build, the cooling gains justify the premium. I keep Kryonaut in my arsenal specifically for thermally challenging situations where every degree counts.
Kryonaut shines in high-performance mini PCs used for gaming, content creation, or scientific computing. It’s ideal for systems running near thermal limits where every degree of improvement matters. I particularly recommend it for mini PCs with AMD Ryzen processors that tend to run hot, or for any system experiencing thermal throttling under load. The premium price is justified for enthusiast builds where maximum performance is the priority.
Less is more with Kryonaut – use about half the amount you would with standard thermal paste. The high viscosity means a small amount spreads further than expected. Clean surfaces thoroughly before application, as the paste performs best on perfectly flat, clean surfaces. Avoid using it on vertical surfaces or direct-die applications where pump-out could occur. The included spatula is actually useful – use it for precise application rather than finger spreading.
Double-sided clip
10-20°C cooling
Thermal pads included
NVMe SSDs in mini PCs can reach concerning temperatures under sustained load, potentially causing throttling that affects storage performance. This SGTKJSJS M.2 heatsink solves that problem effectively. I’ve tested it on multiple Samsung 970 and 980 Pro drives, consistently seeing temperature reductions of 10-20°C during intensive file transfers and benchmarks.
The double-sided clip design is genius – it makes installation foolproof compared to thermal pad-only solutions. I simply position the heatsink over the SSD, apply gentle pressure, and the clips lock it securely in place. No messy adhesive cleanup, no worrying about pad placement, and most importantly, no risk of shorting components on the motherboard.
The aluminum alloy construction with silver plating provides excellent heat dissipation while eliminating static electricity risks. The anodic oxidation surface treatment ensures long-term durability without corrosion. I particularly appreciate that this fits perfectly in the PS5 expansion slot, making it ideal for storage upgrades in Sony’s console as well as PC applications.
Included thermal silicone pads offer good conductivity without being overly aggressive. They conduct heat efficiently from the SSD controller to the heatsink without damaging the delicate components. The 1.44-ounce weight adds minimal mass while providing substantial cooling surface area. At under $7, this is one of the most cost-effective performance upgrades available for mini PCs with NVMe storage.
This heatsink works best with standard M.2 2280 NVMe SSDs. I’ve successfully installed it on Samsung 860/960/970 EVO, 970 Pro, and 980 Pro drives without issues. The double-sided clip design accommodates various SSD heights, making it versatile for different motherboard layouts. Before purchasing, verify your mini PC has clearance around the M.2 slot – some ultra-compact models may have constrained spacing.
High-speed NVMe drives can throttle when temperatures exceed 70°C. This heatsink keeps my drives in the 50-60°C range even during sustained 3.5GB/s transfers. The difference is noticeable in real-world use – large file copies complete faster without thermal intervention, and system responsiveness remains consistent during intensive storage operations. For mini PCs used as media servers or running databases, this upgrade provides tangible performance benefits.
4 heatsinks included
Groove design
Rubber band installation
When you need to cool multiple NVMe drives, this ELUTENG 4-pack delivers exceptional value. At under $7 for four heatsinks, it’s an unbeatable solution for mini PCs with multiple M.2 slots or for builders maintaining several systems. I’ve installed these across three different mini PC builds with consistent results – NVMe temperatures that previously spiked to 70°C now stay in the comfortable 50-60°C range under load.
The groove design significantly increases heat dissipation surface area compared to flat heatsinks. This matters because more surface area means more efficient heat transfer to ambient air. The alloy aluminum oxidation construction provides excellent thermal conductivity while resisting corrosion over time. I particularly like that these use a dual installation solution – you can use either metal clips or rubber bands depending on your preference.
The rubber band installation method is surprisingly secure and easier than traditional thermal tape. No need to clean old adhesive, no worrying about alignment – just position the heatsink and wrap the rubber bands around. The black rubber bands are unobtrusive and don’t interfere with nearby components. For a more permanent solution, the included metal clips provide rock-solid mounting once positioned correctly.
Each heatsink comes with a thermal pad that offers good conductivity without the mess of liquid thermal compounds. The pads compress properly under mounting pressure, ensuring full contact between the SSD and heatsink. The low profile design fits comfortably in tight spaces where taller heatsinks might interfere with GPU risers or other components.
Modern mini PCs often feature two or more M.2 slots. This 4-pack gives you cooling for all your NVMe drives with one purchase. I’ve used it successfully on systems running multiple Samsung 980 Pro drives, keeping all storage temperatures in check during simultaneous intensive operations. The consistent cooling across all drives prevents thermal issues that could affect system stability or storage performance.
While the rubber bands provide easy installation, they may degrade over very long periods. For permanent installations, I recommend switching to the metal clips after initial testing. The aluminum construction shows no signs of corrosion after six months of continuous use. The thermal pads maintain their conductivity without drying out or becoming brittle, ensuring sustained performance over time.
120mm USB fan
18dBA noise
52 CFM airflow
This AC Infinity MULTIFAN S3 has earned a permanent place in my testing setup due to its incredible versatility. With over 36,000 reviews and a 4.6-star rating, it’s clearly a community favorite. The ultra-quiet 18dBA operation makes it perfect for noise-sensitive environments while still moving 52 CFM of air – impressive for such a compact fan.
I’ve used this fan for cooling mini PCs, routers, AV receivers, and even as an exhaust fan for enclosed cabinets. The multi-speed controller lets me dial in exactly the right balance between airflow and noise for each situation. For mini PCs specifically, I place this about 6 inches away, set to medium speed, and see 5-8°C temperature reductions without any perceptible noise increase.
The dual-ball bearing design provides a 67,000-hour lifespan, which means years of reliable operation. I have two of these fans that have been running continuously for over two years with zero issues. The USB power connection makes it incredibly easy to deploy – just plug into any available USB port on the mini PC or a USB power adapter. The fan can lay flat or stand upright, giving flexibility in positioning.
Rubber anti-vibration feet prevent the fan from walking across surfaces while reducing transmitted noise. The build quality is excellent despite the affordable price, with sturdy construction that doesn’t flex or rattle. At under $15, this is one of the most cost-effective cooling upgrades available for virtually any electronics, not just mini PCs.
Position this fan to blow air across the mini PC’s vents, not directly into them. I’ve found the sweet spot is 4-8 inches away at a slight angle, creating cross-flow across the entire case. This setup works best when the mini PC is placed on a stand that allows airflow underneath – combining this USB fan with a cooling pad creates a comprehensive cooling solution that addresses both internal and external heat management.
The fan draws minimal power and can be powered by any USB port. I’ve successfully daisy-chained multiple units using a USB hub when cooling larger equipment racks. The 4.7-inch square footprint fits easily in most setups without requiring significant space. For mini PC users concerned about USB port availability, a small USB power adapter provides a dedicated power source without consuming system resources.
3-speed controller
21dB on low
65,000 hour bearing
For tight spaces where the 120mm AC Infinity won’t fit, this 80mm SCCCF fan is my go-to solution. At just 3.64 inches square, it fits in cramped enclosures and smaller setups while still delivering impressive cooling performance. The three-speed controller provides excellent flexibility – I keep mine on low most of the time, where it’s virtually silent at 21dB.

I recommend starting on the lowest speed setting and only increasing if necessary. The low setting provides adequate airflow for most mini PC applications while remaining nearly inaudible even in quiet rooms. Medium speed becomes useful during intensive tasks like gaming or video rendering. Reserve the high setting for temporary cooling bursts or particularly demanding situations, as the noise becomes more noticeable at maximum RPM.
The compact size makes this fan perfect for placing directly beside mini PCs in tight spaces. I’ve found it works exceptionally well when positioned to blow air across the side vents of mini PCs, creating cross-flow cooling. For particularly cramped setups, the fan can be mounted vertically using adhesive Velcro strips, taking advantage of the rubber feet that prevent vibration transfer to the mounting surface.

However, 12+ core AMD CPUs or Intel i9 processors may exceed this cooler’s capacity under sustained all-core loads. Know your hardware’s thermal requirements before choosing this cooler.
20% better than MX-4
Improved conductivity
Non-conductive
ARCTIC MX-6 represents the evolution of the legendary MX-4 formula, delivering 20% better thermal performance while maintaining the same safety characteristics that made MX-4 popular. I’ve been testing MX-6 for six months across various mini PC builds, and the results are impressive – temperatures run 3-5°C cooler than with MX-4 in identical setups.
The improved thermal conductivity makes a noticeable difference in demanding applications. On a thermally constrained mini PC gaming at 4K, MX-6 kept the CPU 4°C cooler than MX-4 under sustained load. This doesn’t sound like much, but it’s often enough to prevent thermal throttling that would otherwise impact framerates. The lower thermal resistance translates directly to better sustained performance.
Like its predecessor, MX-6 is neither electrically conductive nor capacitive, eliminating short circuit risks during application. This makes it safe for use in any application, including direct-die cooling scenarios for GPUs and console processors. The viscosity is slightly higher than MX-4, which I actually prefer – it stays where you put it during application and doesn’t migrate over time.
The authenticity check included with each tube is a nice touch, ensuring you’re getting genuine ARCTIC product. This matters because counterfeit thermal paste is unfortunately common in online marketplaces. The 4g tube provides enough material for multiple applications, maintaining excellent value despite the premium over MX-4.
If you’re building a high-performance mini PC for gaming, content creation, or scientific computing, MX-6 is worth the small price premium. The improved thermal performance makes a meaningful difference in thermally challenging situations. For everyday office PCs or media servers, MX-4 remains perfectly adequate and offers better value. I recommend MX-6 for systems running near thermal limits or where maximum performance is the priority.
Apply slightly less MX-6 than MX-4 – the higher viscosity means it spreads further under mounting pressure. A pea-sized amount is still appropriate for most CPUs, but use a slightly smaller pea for GPUs. The included spreader isn’t necessary – mounting pressure will distribute the paste optimally. Avoid spreading too thin, as MX-6 performs best with moderate application thickness similar to MX-4.
This kit of 20 miniature heatsinks solves overheating issues for small components that traditional cooling solutions can’t address. I’ve used these heatsinks on VRMs, RAM chips, MOSFETs, and even Raspberry Pi CPUs with excellent results.

Whether you’re cooling a single device or an entire equipment rack, this versatile fan delivers the performance needed to keep temperatures under control.
Start with the Low setting for everyday use – it provides adequate cooling while remaining nearly silent. Move to Medium for intensive tasks like gaming or video rendering. Reserve the High setting for temporary cooling bursts or particularly demanding situations. The ability to turn the fan completely off is convenient for times when you need absolute silence and can tolerate temporarily higher temperatures.
The included screw mounting hardware allows permanent installation if desired. However, I prefer using the fan freestanding with the silicone feet, as this provides more flexibility and reduces vibration transmission. The 4.72-inch square footprint fits easily in most setups. The fan is sturdy enough to support lightweight devices placed directly on top, creating a convenient cooling platform for mini PCs or routers.
Selecting the appropriate cooling solution for your mini PC requires careful consideration of several factors. The thermal design power (TDP) of your processor plays a significant role – high-performance CPUs generate more heat and demand robust cooling solutions. Assess your typical workload as well; gaming and video editing generate sustained heat that requires better cooling than light office work.
Noise tolerance varies significantly between users. If your mini PC sits in a living area or bedroom, prioritize quiet solutions like the X3 140mm fan or ARCTIC thermal pastes that don’t require aggressive fan speeds. For office environments or equipment closets, noise becomes less critical and you can focus on maximum cooling performance regardless of acoustic output. Similar to how ferrofluid cooling technology helps audio equipment manage heat efficiently in small enclosures, choosing the right cooling approach for your mini PC depends on understanding your specific thermal and acoustic requirements.
Consider your technical comfort level with installation. Thermal paste replacement requires disassembly and careful application, while USB cooling fans offer plug-and-play simplicity. Liquid cooling AIOs demand more installation expertise than simple air cooling solutions. Choose solutions that match your skills and willingness to perform maintenance over time.
Before investing in cooling upgrades, establish baseline temperature measurements using software like HWMonitor, Core Temp, or your motherboard’s monitoring utility. Understanding your current thermal situation helps identify specific problems and measure the effectiveness of cooling upgrades. Look for thermal throttling – when your CPU reduces performance to stay within safe temperature limits – as this indicates inadequate cooling.
Safe operating temperatures vary by processor, but generally staying under 80°C under load is ideal. AMD Ryzen processors typically handle heat better than Intel chips, but both benefit from keeping temperatures lower. Monitor both CPU and GPU temperatures during realistic workloads to get accurate data for your specific usage patterns.
Software optimization can improve cooling without hardware changes. Adjust fan curves in BIOS or using manufacturer software to ramp up fans more aggressively when temperatures rise. Underclocking or undervolting can reduce heat generation at the cost of minimal performance loss. Ensure proper ventilation around your mini PC – maintaining 10cm of clearance on all sides makes a surprising difference.
Before modifying your mini PC’s cooling, check whether your warranty remains intact. Some manufacturers consider opening the case a warranty-voiding action, while others encourage user upgrades. External cooling solutions like USB fans or cooling pads generally don’t affect warranties, but internal modifications like thermal paste replacement might.
Document your system’s original condition before making changes. Take photos of stock thermal paste application, cable routing, and component placement. This documentation proves valuable if you need to restore the system for warranty service or if you want to compare before-and-after temperatures from your cooling upgrades.
Consider the reversibility of any modifications. Thermal paste changes are easily reversed, but drilling mounting holes or cutting case panels are permanent changes that affect resale value and warranty coverage. Start with non-invasive cooling solutions before attempting more aggressive modifications that can’t be undone.
Start with external solutions like USB cooling fans positioned to create cross-flow across vents. Replace stock thermal paste with quality compound like ARCTIC MX-4 for 15-25°C improvements. Ensure 10cm clearance around all vents and avoid placing the mini PC on soft surfaces. For advanced users, upgrading to an AIO liquid cooler in compatible cases provides maximum cooling performance.
Not necessarily – many modern mini PCs from brands like Beelink and Minisforum have excellent cooling designs. However, the compact size creates thermal challenges that can lead to higher temperatures than larger systems. Stock thermal paste is often poorly applied, creating easily fixable cooling issues. Understanding your specific mini PC’s thermal limitations helps set realistic expectations for performance.
Liquid cooling generally provides the most efficient heat transfer for high-performance systems, with 360mm AIO coolers offering exceptional thermal capacity. However, for most mini PCs, quality thermal paste combined with proper airflow provides the best balance of efficiency, cost, and complexity. External cooling fans offer excellent efficiency for thermally constrained mini PCs that can’t accommodate internal cooling upgrades.
Fanless mini PCs rely on passive cooling through heatsinks and case convection. Improving their cooling involves ensuring adequate ambient airflow with USB fans, elevating the unit for better convection, and avoiding hot environments. Some users successfully add small USB fans to blow across heatsink fins, dramatically improving cooling while maintaining near-silent operation. Never block the ventilation on any fanless system.
Yes, cooling pads with active fans provide measurable benefits by creating airflow across the mini PC’s bottom vents. Look for pads with metal fins and multiple fans rather than passive cooling surfaces. The Cooler Master X-Lite 2 is frequently recommended in community forums for its effectiveness with mini PCs. However, cooling pads work best as part of a comprehensive cooling approach rather than a standalone solution.
Effective mini PC cooling requires a comprehensive approach tailored to your specific hardware and usage patterns. Start with simple, reversible solutions like thermal paste replacement and external USB fans before attempting more complex modifications. The ARCTIC MX-4 provides excellent performance for most users, while enthusiasts demanding maximum performance should consider Thermal Grizzly Kryonaut.
External cooling solutions like the AC Infinity MULTIFAN S3 offer versatile improvements that work with virtually any mini PC. For builders working with compatible cases like the NR200, liquid cooling AIOs provide exceptional thermal performance that exceeds traditional air cooling. Remember that the best cooling solution balances temperature reduction, noise levels, and practicality for your specific situation.
Monitor your temperatures before and after modifications to quantify the effectiveness of your cooling upgrades. This data helps identify what’s working and guides further optimization. Community forums frequently report 20-30°C temperature improvements from basic upgrades like thermal paste replacement and external fans – gains that translate directly to better sustained performance and quieter operation.
The mini PC market continues evolving, with brands like Beelink and Minisforum leading innovations in cooling design. As these systems become more powerful, effective cooling becomes increasingly important for maintaining performance and longevity. Whether you’re using a budget-friendly office mini PC or a high-performance gaming rig, the cooling solutions covered in this guide will help you achieve optimal temperatures in 2026 and beyond.
