Hello guys. A friend of mine bought the kit and he hooked up all the connections right. However, the system would shutdown via overheat protection. The system does post but for like 20 seconds. The water block on the cpu has a mirror smooth finished and he used arctic silver. The water pump is pumping and the rad. fan is on. I have no idea why the cooler won't work like it is supposed to. I know that this cooler kit isn't great but it should cool fine for a cpu that is not o/ced'. I am really vague about System specs but they are Asus SLI mobo, AMD x2 +4200, OCZ ram, 2x 7800GT and some power supply I never heard of but it seems of good build (weights more that 5lbs rated at 600watts). Anyone have any clue to this problem?
