Recommend a FAN for the Pentium Pro 1MB 200MHz
Andy Jones
The ambient temperature has increased in our office, and the DEC
Digital Servers are suffering, and alarm at Pentium Pro temps of 80
degrees C (max spec limit). These are Quad servers so it doesn't help,
but we've reduced them to duals and it doesn't make alot of
difference.
We tried fans we've purchased locally and via eBay, and the cheap poor
fans melt with the heat. (these servers our on 24x7).
My guess is that the fans are too close to the small heatsinks, and
heat up, and it warps the bearings or something.
Anyone suggest a CoolerMaster fan, if these will fit or other.....
Sanyo Denki originally supplied heatsinks with Retail Boxed Pentium
Pros which seem to work very well, not too sure if these would work on
1MB chips, we have these on local workststaions at 256/512 cache, with
the bump on the chip.
I don't know if Sanyo Denki still supply these!?

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.

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.

yes Pentium Pro is a Socket 8.

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

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.

Thanks for the good advice.
The DEC Servers have primary and secondary fans which kick in. Air
flow is okay through the servers.
The problem is ambient air temperature in the computer room. It was
30 degrees today, and 34 degrees C outside!
Temp Heat wave in the UK!
Air Conditioning is the only answer, but we've been quoted £6 - £7,000
UK GBP.
Which is very expepsive for a few days in the year when we have these
freak heat waves!
We may examine the replacement of the servers, with new.
We also have stocks of spares for the servers!
Thanks to all that replied.

Don't know if they still make then, but used them for my PR440FX (which I'm
still using today) w/dual fans, really nice units.
