New Best Thermal Paste? Thermalright TFX - Review & Comparison

Within the last one year or so, Thermalright released many new high-end thermal pastes to the market, offering very good thermal performance atleast on paper. 14.3W/m-k for the TFX attracted my eye, so I decided to test the TFX out of pure interest myself, eventhough the paste ended up being very expensive.

I tested the TFX against Kingpincooling KPx and the fine-tuned Thermal Grizzly Kryonaut Liquid Helium Edition on my delidded 9900K R0 stepping, between the die and the water block in a direct die cooling situation. I used the same frequency and voltage profile pretty much as on my previous high-end thermal paste comparison video.

End result was quite as I expected, the TFX is a few degrees behind both the KPx and Kryonaut when compared between the die and the water block. I think this testing method shows a bit more differences between different thermal pastes than when compared on top of the IHS, as the target area is much smaller. Ambient temperature was measured with K-type thermometer and it was constantly around 22.5-23.0 degrees at the end of each test. I tested every paste in Prime95 26.6 in small FFT mode for around 15 minutes, the TFX I tested twice to doublecheck the difference.

So far KPx remains the leader in performance when it comes to testing on water. The result of KPx and Kryonaut LHE are within the margin of error, so it is very hard to pick a clear winner out of the two. The TFX is fairly dry compared to other pastes like KPx, so I will give it a try on 7970 or 2080 ti on ln2 and see if it can survive the common cracking issue.
