Overview

BSFF Thermal Paste, 5.5g with Toolkit CPU Paste sits in our components & replacement parts listings, where we rank by how buyers actually rate a product rather than by brand. The manufacturer says: BSFF is metal-free and non-conductive, which eliminates any risk of short circuit and adds more protection to the CPU and VGA card. It is made of carbon microparticles, guaranteeing extremely high thermal conductivity. This ensures that heat from the CPU/GPU is dissipated quickly & efficiently. Those are the seller's own claims rather than our testing, so treat them as a starting point. On Amazon it holds 4.7 out of 5 from 8,876 ratings. What that score is worth next to its rivals is set out below.

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.

It carries 8,876 ratings against a category median of 2,596. That is enough of a base to take the score seriously without treating it as settled.

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.
