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 can see a bigger difference when looking at noise-normalised thermals, however, where we re-run our thermal tests but with noise output tuned to 40dba. This opens up a big lead for the Lightning Z, considering it hit just 53.5C on the GPU and 62C on the memory, so it does go to show the raw cooling benefits of using the 360mm AIO, even if the power limit of the card is higher, too.
