[rescue] Ultra 1 CPU fans and heat load?

[Bran Tregare]

please tell me more about this FCO... I jsut got an ultra 1 143 and the fan 
was pulled by the previous owner because it fried.  i'm running a 3 ish 
inch case fan blowing on the cpu, tied to the CD-ROM power cable (split 
off) and I know where there is a bunch of ultra 1 170's that are thermal 
exceptioning due to fan failures in them :)
