PowerColor RX 7900 GRE Hellhound 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 at varying noise levels as a result of more aggressive fan curves no longer being a factor.

We then increased fan speed until we hit 40dBa noise, and re-tested thermals. It's not a surprise to see the Hellhound running the coolest of the bunch, with a hot spot that's 4C lower than the Sapphire Pure.

It's also worth bearing in mind that this test does not take into account the power difference between the cards, and as we will see on the next page, the Hellhound also pulls more power than all but the Nitro+, making this result even more impressive.
