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.
We increase fan speed up to 50%, or 1850rpm, to hit 40dBa, and that saw noise-normalised thermals basically matching the Gigabyte Gaming OC, with a GPU temperature of 58C. All three 4070 Tis are in the same ball park, but clearly the GameRock OC is a very efficient cooler design.
Less so for the memory thermals, as the GameRock OC's peak of 60C is 6C warmer than the Gigabyte Gaming OC – but again, a peak of 60C is still fantastic for GDDR6X memory.
