We use an aftermarket fan that uses ballbearings instead f sleave 
bearings on our Cyrix chips, so it has an increased lifespan.  It also 
has a slightly larger blade surface, and keeps the chip cooler than the 
cyrix fan.  Though recently we've gone to the AMD K5's.  They are cheaper, 
cooler, and outperform both Cyrix and Intel.
