Help Please

Ok well, I have my w/c setup and and the fan is running full throttle. I made sure to set it to shut down at 60 C,and it got to BIOS and shut down, and now Im afraid to boot up again cause I don't want to burn it. Anyone have any clues why it is overheating?I made sure I used just the right amount of AS3 and everything. It was cold to the touch, so Im not sure what it is now?

Could be the block isn't seated right on the cpu.

I have it compressed all the way, boots up now at CPU 1 : 40 C
CPU 2: 62C. Why is it such a huge difference? I thought at the most its supposed to be 5C difference?

Do you have the water exiting CPU 1 water block and going into CPU 2 water block? Could explain the difference in temperature.

Yea, I know that, but it shouldnt be 20C difference. Any ideas?
