Pity the chip it will be cooling is not going to be kept in service
for 34 years.
Maybe it has a chance to last that long in an IBM mainframe!

Why would you even waste time on a PC power supply fan? Are you going
to check the capacitors that are very likely going bad too? You can
buy an Antec EarthWatts 380 Watt supply from Fry's for $30. High
efficiency, power factor corrected, auto switch 120/240, variable
speed cooling fan. Isn't your time worth anything?

Funnily enough, I've just replaced one of those today.

Yeah, you can use a generic replacement but if it's powered 24/7 it
won't last long. Find a good quality ball-bearing replacement from the
likes of NMB-Mat, Panasonic or Papst. You'll be glad you did.

Also known as Vapo bearings.

Try a silicone-based lubricant (with a consistency between that of oil
and grease). Expensive but it works.
