Re: Pentium 200 and Pentium Pro 200 builds. Do I need dedicated CPU fans or are nearby 80mm case fans enough?

The Serpent Rider wrote on 2023-12-04, 06:59: Pentium 200 will require active cooling on that motherboard. The radiator is sitting very closely to linear voltage regulators. Interestingly when I stress tested the system, it seemed like the voltage regulator heatsinks got warmer than the main …

Your Pentium 1 heatsink is already pretty large (compared to the stock/OEM one), so a bit of airflow should be heaps. This is my thinking too. It's got a lot more area for heat dispersion than a stock heatsink and coupled with a decent amount of adjacent airflow should be enough to keep it cool.

I think you could get away with some good case airflow and a big passive heatsink, you can get some really good high CFM fans from noctua that wouldn't look odd in a retro build. I was comparing airflow of the various Noctua fans. The 80mm fan do push a lot more air than the smaller ones. R8 redux- …

After seeing https://www.vogons.org/viewtopic.php?p=1216263#p1216263 I would most definately recommend some shroud as, unless the picture plays tricks on my eyes, it looks like the fan is something like 20 mm "higher" than the motherboard? Closer to 40mm. The top of the heatsink is 35mm from the …

Ducting is a good idea. I can fabricate something out of acrylic if need be. FWIW, I tested this setup for over an hour. Installed all the intended cards, closed up the case and then ran various demos and games. The heatsink did warm up, but not unbearably so. I could easily keep my hand pressed on …

Pentium 200 and Pentium Pro 200 builds. Do I need dedicated CPU fans or are nearby 80mm case fans enough?

I'm in the process of building two systems: Pentium 200 and a Pentium Pro 200. The heatsinks I have for both processors don't allow for easy attachment of dedicated fans. For the Pentium 200, I would normally use a low-profile copper heatsink with fan attachment points, but on this particular …
