Cold Computer Booting

Interesting problem here.
I turn the heat way down at night. Call it about 60 degrees F as the ambient temperature in the office (at home). One of the computers, when it gets cold outside, and therefore cold inside (around 60F) the computer will not make it past the memory check screen in the first boot, and the CPU fan is quite noisy. I leave it for a couple minutes to warm up, turn it off and back on again, and it's fine. The obvious is, that I need a CPU fan, understood. But, I cannot understand what would prevent the normal boot when the computer is very cold. Even with a noisy fan, it is still cooling, and if it wasn't, I wouldn't think that the overheating would occur in 1 second.

Any comments are appreciated.

Some times with excess dust in the fans and/or heatsink causes the noise you are speaking about, especially when the rig is cold. Might be worth it to get a can of compressed air and blow those fans and everything else in that case out. One should keep them clean anyhow, so what can you lose by trying that.
