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.
Rounding off the thermal testing, here we have noise-normalised the fan speeds of each graphics card to 40dBa, which actually required a fan speed of 92% – or 1770rpm – for the Noctua Edition RTX 3070. Unsurprisingly, that dropped GPU temperatures significantly, down to a peak of 47C with a hot spot of 59C – which is almost 20C cooler than the Nvidia Founders Edition.
