PowerColor RX 7900 XTX Hellhound Spectral White Review

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.

Moving onto noise normalised thermals, for this testing we had to increase fan speed up to 53%, or about 1675rpm, to hit 40dBa of noise. Unsurprisingly, the Spectral White really shines against the reference card here, with the GPU temperature peaking at just 52C, while the hot spot temperature hit 73C – a massive 16 degree reduction compared to AMD’s own card. The Spectral White is clearly just a much more efficient cooler.
