Testing (Continued):
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 of the Antec Truepower Quattro 1000W were lower than I expected with an 80mm cooling fan, but the downside to this is rotational speeds approaching twice that of the more commonly used 135-140mm fans . The fan noise was quite noticeable at 2901RPM, but the power supply was loaded at a near maximum level of 975W – a level most users just won't reach, but more on that later.
