Built myself a PC with one of these today, only problem is - it won't start.
I've double checked all the connections, they're secure. The Default HSF from the E6600 is secured, and the power supply (FSP 500Watt) is more than adequate. I press the start button, and all the fans except for the CPU fan spin for a second or two, then the PC turns itself off and repeats the same thing again indeffinately.
The CPU fan tries to spin, it sort of spasms when I first press the on button and then again when the PC automatically turns off after a second or two. It's not blocked or anything, it just doesn't seem to spin.
Also - how the hell do you get the CPU fan connector off the motherboard. It's like the ruddy thing's glued on, and no ammount of effort will remove it.
