StarTech HEATGREASE20 (Ceramic-Silicone/Non-Conductive/20g Tube/Budget Bulk Compound) Review

StarTech HEATGREASE20 ceramic-silicone thermal paste, 20g tube, made in USA, for CPU heatsinks

HEATGREASE20 is StarTech's large-format 20g tube of white ceramic-based thermal grease, aimed at system builders and repair shops who need enough compound for many low-end to mainstream installations rather than a single high-performance application.

Overview

A 20g tube of ceramic-based, silicone-containing thermal grease rated for -20°C to 100°C operation, with low bleed and evaporation figures published on StarTech's datasheet.

Best Use Case

Best suited to system builders assembling many low-end to mainstream systems who need a large-volume, economical compound rather than a premium high-conductivity paste.
