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.

Once we noise-normalised to 40dBa, there's honestly very little difference between the thermal performance of all three 4080 Supers tested. The JetStream OC is within 1C of the Founders Edition, while it's just 1.5C hotter than the Gigabyte Gaming OC

Noise-normalised memory thermals do show a slightly larger win for the JetStream OC over the FE, with a peak temperature that's 4C cooler, but the Gaming OC is the clear winner here.
