Temperature, Noise Levels and Fan Speeds:

I am not going to give a pass or fail in this section, as the ATX12V V2.2 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 concerned me a little, as they are so much higher than other power supplies I’ve tested and an exhaust temperature of 53.8 °C is rather high. The fan remained at a relatively low speed of 700RPM throughout testing, which is unusual and certainly keeps things quiet. I introduced a little warm air into the power supply from my load and the fan ramped up to 1300RPM almost immediately, which indicates a possible drawback to out of case testing? The temperature control threshold is obviously set a little higher and the fan would probably kick in sooner when mounted at the top of a case, drawing in warmer air, but I can only see it running hot when bottom-mounted and drawing in room air. In any case, who buys a power supply and runs it at or near full load all the time?
