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 at varying noise levels as a result of more aggressive fan curves no longer being a factor.

The noise-normalised thermal results didn't go quite how I was expecting, with the Nitro+ running hotter than the Pulse and the Pure, despite a larger cooler. It's worth reminding ourselves that while we can normalise for noise, all four GPUs do have different power targets, with the Nitro+ pulling about an extra 40W, which could explain the difference. All four models tested improve on the AMD reference design though and I really have no concerns about any of the coolers on show today.
