Overview
Tube-packed thermal paste goes between a processor and its cooler to improve heat transfer. This ARCTIC listing gives a small package size and a paste amount in the title, and nothing else about composition or conductivity.
A processor-agnostic paste in a small tube is the reason to consider it for a cooler swap or a new build. The limit is data: conductivity, curing time and applicator details are all missing from the listing.
Who it's for
PC builders and upgraders refitting a CPU cooler will use a tube of this size. Overclockers who want specified thermal figures should check the manufacturer sheet first.
Pros and cons
- Works with all processors per title
- Small tube suits one or two jobs
- Thermal conductivity not listed
- Not a thermal pad
- Cleaning supplies not mentioned
Performance notes
Paste fills the microscopic gaps between a processor lid and a cooler plate, which lets heat move across the joint. Results depend on a thin even layer, because too much paste insulates. The listing gives no figures, so any performance comparison comes from the maker.
