I am not going to give a pass or fail in this section, as the ATX12V V2.2 specification does not really have any references on which to base a decision.

Temperatures are purely for information only, as there are too many variables involved when installed in a case, which, by the way, it wasn't. Ambient temperature, processor cooling efficiency, and case cooling fans all play their part on the temperature of the air entering the power supply, and consequently the temperature of the air leaving it. No valid conclusions can be made from this test.

The temperatures do seem quite reasonable but just bear in mind that the temperature of the air going in will be higher when installed in a case. Literature provided to me with the Corsair HX1000W shows a constant fan speed up to approximately 500W (which has been demonstrated during testing), giving a noise level of 24dBA, at which point it slowly ramps up to give a noise level of 44dBA at 1000W loading. If you don't expect to load the HX1000W much above 600W then you will have a very quiet power supply but at 1000W, with a fan speed of 2000RPM, the fan noise increases noticeabily but is not excessively noisy.
