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.
As the 6800 XT is so quiet in its out of the box state, we re-tested its thermal performance but with noise levels fixed at 40dBa. This meant increasing the fan speed from 1350rpm up to 1720rpm, resulting in a 10C reduction to the peak edge temperature. Meanwhile, the junction temperature dropped from 98C to 85C.
As mentioned, AMD was clearly trying to tune this reference design for the lowest possible noise levels, but if you are happy to tweak the stock fan curve, this cooler can deliver some highly impressive thermal results.
