MSI RTX 4090 Suprim Liquid X Review

Following on from our stock thermal and acoustic testing, here we re-test the operating temperature of the GPU, but with noise levels normalised to 40dBa. This allows us to measure the efficiency of the overall cooling solution as varying noise levels as a result of more aggressive fan curves are no longer a factor.

Raising fan speeds to hit 40dBa, we can see noise-normalised GPU temperatures are the best yet, with the Suprim Liquid X keeping the GPU about 5C cooler than the Palit GameRock OC. The hot spot temperature is still running a bit hotter however, coming in just shy of 70C.

Likewise for the memory modules, a noise-normalised result of 74C makes this warmer than both air-cooled AIB cards we've tested, though it is still an improvement on the Founders.
