Hi, you mentioned this to be a homemade system
with all 3 fans plugging directly into the motherboard.
I'm geussing these are the common 3 pin fan connectors
on the motherboard, which are hot, ground, and signal.
Any chance you're going from signal voltage to ground
instead of hot to ground ? This would cause a bi-polar
transistor to fail, eventually. To test this, parallel
your fans off a hard drive connector and ensure the fans
are still good. Hopefully, your cpu is in fact locking up
do to the heat and not because of a damaged motherboard
transistor.

I had this happen to me on a customer's cyrix system.
When their fans stopped working the level 2 external
cache fried. To determine this I disabled the L2 cache in
BIOS and the system would work, but slow.
