Recommend a FAN for the Pentium Pro 1MB 200MHz

Depending on how much clearance is in the case above the CPUs, try putting
in longer screws with spacers between the HS and fan. Maybe this will help
temporarily to stop the fans from overheating from contact with the
heatsink. Rubber washers of some type, or those old motherboard case mounts
washers.

The Socket 8 CPU heatsink is huge and will certainly accommodate almost any
CPU fan out there. Clearance is the problem.

Otherwise, more case fans can be used to move more air through the case
helping the CPU fans. Maybe you can direct air at the CPUs with a jury
rigged case fan pointing at the CPUs. If there are no free case fan opening
try, slot fans, bay fan, etc to move more air. Replace the case fans
existing with much stronger ones. Also check that you Power Supply fans are
doing their job. Maybe there are shot or so full of dust they are working
inefficiently.

My guess is the cooling in the servers is not working properly, the problems
with the CPU fans is a symptom, not the cause. There servers seem to have a
cooling problem. Removing CPUs from a quad to two is a great drop in heat
so think about the box as a whole, not the CPU.

If your Digital servers are in a closed locked room, increase airflow to the
room. You can get a water cooled circulating air-conditioner installed to
cool the room but expensive. Why has your office ambient temperature
increased? Temp heat wave or permanent problem?

Last, time to upgrade those old servers ... What if a major system
failure?? Do you have a service contract? Using such old technology in a
production environment is a recipe for disaster unless you have a service
contract with someone reliable in old tech or you had better have lots of
spare parts on hand and maintain your own spare parts inventory. I have
seen production lines go down because they were running on an old XT PC that
finally died after 10 years and no service contract, no one knows anything
about the equipment. A major NHL hockey team rink scoreboards ran on old
386 PCs that crapped out and they went scrambling for parts/replacements in
the used computer stores as way too old for anyone to service. Funny how an
old 386SX system went for a couple of $100 to someone desperate a couple of
years back. All too typical in today's world, it takes a disaster to get
something done that should have been replaced long ago.

If I were you, I would get the budget to replace that server(s) with a
modern one. Normally, you never get a chance to avoid disaster by having
warning signs, you certainly have some now and if lucky will remove the
threat to your company. Anticipate instead of react to the problem.

You could probably replace all your Digital servers with one 2+ GHz system,
reduce operating costs (electricity etc), etc.

Try calling an AC company, fans wont help much if the ambient temps rise
too high.

yes Pentium Pro is a Socket 8.

I don't think a socket A HSF will work, I just looked at an old socket 8
(Pentium pro)CPU, and it is much larger than a socket Athlon or Pentium 4.

...

Pentium Pro is socket based isnt it?

If it is try a socket A heatsink on them, get a cheap one, and it will be
massivley over specified for the application.
