We use Am5x86 here exclusivly for our servers and most of our workstations. These have the 486-size CPU... We were plagued with fan failures occasionally until I was able to find some good fans (ball bearings) and cheap enough to change them all every 3-4 months. Costs me $35 to walk around and swap them all out, I stick them in a box... if I have one of the newer ones fail I can always go back to one of the old ones (if I am out of new ones) or give the old ones to friends w/ fan problems, etc etc. plus, keeping the fan/heat sink clean REALLY helps. I try to clean ours at least once a month with pressurized air - in extreme cases remove the heat sink (re-greasing it afterward) and get rid of the dust/crap on it. Still, it doesn't seem they want to make CPU fans that want to work in tower cases.... JS
