Check price on Amazon →Overview
This 4g tube uses carbon microparticles for high thermal conductivity, helping shift heat off a CPU or GPU quickly. Because it is metal-free and non-conductive, there is no risk of shorting components if a little strays where it shouldn't, which makes it forgiving for first-timers. The formula holds up over time rather than drying out and needing regular reapplication, and its consistency spreads easily. A near-perfect 4.7 stars from over 104,000 buyers tells you builders trust it. Check the current price on Amazon before you order.

How it compares in Components & Replacement Parts
Across the 44 rated components & replacement parts products we track, the typical score is 4.6 out of 5. This one sits at 4.7, which is around the middle of the category. Ratings alone will not separate it from its rivals here, so price and the specifics below matter more than the star count. That places it second of the 44 we rank here.
It carries 104,532 ratings against a category median of 2,596. A rating from a large base is harder to distort and tends to hold up over time, so a high score here means more than the same score on a new listing.
On price it sits in the lower third of a category running from £4.99 to £625, where the midpoint is about £39.99. Cheaper than most while rating at or above the category norm is the combination worth looking for, and it is the main argument for this one.

Key features
- CONSISTENT QUALITY: Our thermal paste packaging design has evolved over time, but the formula has remained the same, ensuring reliable performance.
- EXCELLENT PERFORMANCE: ARCTIC MX-4 thermal paste is made of carbon microparticles, guaranteeing extremely high thermal conductivity. This ensures that heat from the CPU/GPU is dissipated quickly & efficiently
- SAFE APPLICATION: The MX-4 is metal-free and non-electrical conductive which eliminates any risks of causing short circuit, adding more protection to the CPU and VGA cards
- HIGH DURABILITY: In contrast to metal and silicon thermal compound, the MX-4 does not compromise over time. Once applied, you do not need to apply it again as it will last at least for 8 years
- EASY TO APPLY: With an ideal consistency, the MX-4 is very easy to use, even for beginners
