GPU temperaturesWe have shown the various GPU temperatures at idle and in load.
We have displayed the readings at idle for the card on its own and the readings in load for the whole system, which doesn’t change anything for the noisiest cards, which totally cover the noise levels of the casing (34.1 dBA).
While almost all the manufacturers do a little bit better, even a lot better (MSI and Zotac) than the reference model at idle, the EVGA GTX 580 Classified is the exception to the rule.
In load, there is more of a difference between the cards and the Zotac card clearly does best. Asus and Gigabyte do better than the reference card, while the Gainward is noisier, as is the MSI, which suffers here from a poorly calibrated fan, and the EVGA cooler, which probably needs to be sent back to the drawing board.
