PCCooler EX90 Review

PCCooler EX90 is the brand's flagship thermal paste, rated 14.8 W/mK in a 4g tube with a bundled scraper tool.

It's PCCooler's highest published conductivity number, competitive with Thermalright TFX and Alphacool Apex 2 on paper.

Thermal Performance and Conductivity

14.8 W/mK is the top of PCCooler's own lineup, ahead of GT-10 (13.6 W/mK), GT-2 (9.8 W/mK), and A1 (>7.5 W/mK).

Application and Consistency

Gray paste, 2.6 g/cm3 density, sold in a 4g tube with an included scraper tool for spreading.

Comparison to Alternatives

Against Thermalright TFX (14.3 W/mK), EX90 edges it out slightly on paper, though TFX has a much longer independent review track record in enthusiast circles.
