Thermalright Intros CFX Thermal Compound with Wide Temperature Range

btarunr · Dec 22, 2021

Thermalright today introduced the CFX thermal compound. The compound offers a wide temperature range of -50°C to 150°C, while being electrically non-conductive. Its conductivity is rated at 12 W/m-K, with a thermal impedance of 0.009 °C-cm²/W, and has a specific gravity of 2.3 at 25°C. The company didn't mention the composition or viscosity of the paste. It ships in 2 g syringes and includes a spatula, so it could be more on the viscous side. The company didn't reveal pricing or availability.

I am confused. I bought a PA120 from Thermalright recently which came with TF7 thermal paste, which has a far wider temperature range than this product (-150⁰c to 250⁰c). Marginally better thermal conductivity, which usually means nothing, but this is within a single brand so maybe it's a bit more hinged on reality?

I don't understand how this CFX improves upon TF7. What am I missing?

Paste has more parameters like viscosity and most importantly longevity shelf life.

Also, how does this compare to the TFX, which has been out for quite some time?
