Kryonaut is a high-performance thermal paste with quoted conductivity of 12.5 W/mK, aimed at builders who want to keep a hot CPU, GPU or games console running cool. It is neither electrically conductive nor capacitive, so a slightly messy application will not short anything out, and a small spatula is included to spread it evenly. The 1g tube covers a few applications depending on chip size. A 4.7 average from over 61,000 buyers is excellent and matches its strong reputation.

How it compares in Components & Replacement Parts
Across the 42 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 4th of the 42 we rank here.
It carries 61,713 ratings against a category median of 2,640. 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 £820, where the midpoint is about £44.85. 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.
