Page 3 of 5 Cooling: The cooling in the Enermax Infiniti is taken care of with a single 135mm fan in the base of the unit blowing into the power supply. It is covered in typical Enermax style with a golden fan grill to keep cables and wayward fingers from coming to strife. There is also a feature within the Infiniti called PowerGaurd, whereby if you shut off the PC and the PSU temperature is above 45 Degrees Celsius, it will keep its fan going, as well as all the other fans in the system either until the temperature falls below 45 degrees, or for 1 minute, whichever comes first. If the PC is shut off and the PSU temperature is already below 45 degrees, it will still keep itself and the other fans going for 10 seconds to cool everything off. We tested this PowerGaurd system on our OzHardware test bench with the ASUS P5N32-E SLI motherboard and ASUS 8800GTS Video card, as well as an Intel E6600, 2 hard drives and DVD drive. For our first couple of attempts we only got the basic 10 seconds of cooling, mostly because our office is quite cool and the components are out in the open on a test bench, not stuffed into a case soaking up heat. So to get the full 1 minute of power on shutdown we blocked off part of the Enermax Infiniti’s intake fan and loaded up the system by running 3DMark06 in a loop for an hour. This would do the trick we thought, so we stopped the loop and shut down the PC straight away and removed the partial blockage (i.e. Piece of paper) from over the PSU’s intake fan to give it back its full cooling potential. The display shut off, as well as the hard drives, but all the fans in the system continued at their normal rate, for longer than was expected as well, going on for 1 minute 20 seconds before the PSU and fans finally shut off. During this time the graphics card dropped from 57 degrees-C down to 47 degrees-C, so it does its job nicely to help cool the components down before cutting off the juice.
