Hi Alex, No the PSU fan doesn't spin. Nothing happens at all when I press the power button. I think either the PSU / case is not compatible with the new motherboard or the motherboard is faulty. The PSU is quite old as I had to use a molex to 4 pin adapter + a molex to sata adapter. I've just put the old motherboard back into the case again and that is working fine. The old motherboard has a AMD XP CPU. • From: "Alex Stone" <alex.stone@xxxxxxxxx> • To: <access-uk@xxxxxxxxxxxxx> • Date: Sun, 3 Apr 2011 00:14:44 +0100 Mohammed, does the fan in the PSU come on?
