Thermalright TFX (Silicone-Based/Non-Conductive/Flagship TF-Series Paste/14.3 W/mK) Review
If you're checking thermalright tfx thermal paste specs because it's been called the new number-one paste on Overclock.net, here's the real spec sheet.
TFX is Thermalright's flagship compound, and at 14.3 W/mK it beats the Thermal Grizzly Kryonaut Extreme already in this catalog (14.2 W/mK) on paper, while typically costing a fraction of the price.
Thermal Performance
14.3 W/mK is the highest rated conductivity in Thermalright's TF lineup, ahead of the TF8 (13.8 W/mK) and TF7 (12.8 W/mK) we've also added, and it edges out the Thermal Grizzly Kryonaut Extreme on the spec sheet.
Application
igor'sLAB's teardown found TFX has even larger, coarser filler particles than the TF8, making it noticeably harder to spread and closer to a putty than a paste, this is a paste for someone willing to fight the application for the performance.
Safety
Non-electrically conductive and rated harmless by Thermalright.
