Zotac RTX 3090 AMP Extreme Holo 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.

The AMP Extreme Holo tops the charts in both noise-normalised tests, when compared to the other two RTX 3090s we have tested. To hit 40dBa noise output, we had to decrease fan speed to 70%, or 1600rpm, which is a fair bit slower than the out-of-the-box behaviour, resulting in increased temperatures.

This is, though, while also dealing with an extra 70W power draw, so the results shouldn't come as too much of a surprise, but it goes to show just how much cooling power is really required for a high-end power-hungry GPU like this.
