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.

Temperatures along with fan noise levels remained low at all times no doubt helped by high efficiency, relatively low fan speeds and the special "flower" shaped design of the cooling fan blades. The Thermaltake Toughpower Grand 1200W power supply uses FanDelayCool technology and in the case of the review sample the cooling fan ran for almost two minutes after power supply shutdown to improve cooling.
It was briefly mentioned earlier that there is a panel on the rear of the power supply that lights up when the power supply is running. Well here it is.
