I was getting a lot of grief from my fan too, the thing would seize up
every once in a while when it was running in its slow mode, the machine
would over heat and crash. So I called randy suess over on chinet and
he told me how to bypass the speed control for the fan. I did that and
it helped a little but the machine would still just hang for no apparent
reason. Finally I realized that the fan was probably sucking too much
current out of the 12v section of the power supply (remember, this fan
seizes up at slow speeds) and I replaced it with a 110v version. Its
been up without a single crash for almost a week now. Hope this helps...
