| Jul 29, 2018 at 21:58 | comment | added | Jules | @fadden - I ran a 100MHz Pentium 24hrs a day for approximately 5 years without any form of heat sink, and it never suffered from it. Having adequate airflow in the case is enough; a fan was only necessary if that wasn't possible. The Pentium 100MHz had a typical dissipation of about 4W; without a heat sink and with moderate airflow its thermal resistance is about 12C/W, which means that as long as the case temperature remains under about 35C it'll stay at a reasonable temperature that's unlikely to cause harm. I should have used a heat sink for it, but practically it was fine without. | |
| Jul 29, 2018 at 17:50 | comment | added | fadden | Looking at my PC construction history (fadden.com/tech/my-pcs.html), my 90MHz Pentium 90 from 1995 had a CPU heat sink + fan. The 266MHz Pentium-II that went into a machine in 1997 came on a card with the heat sink and fan built in. I don't know that it was necessary, but IIRC it was pretty typical for 90MHz Pentium and later to have a fan. | |

| Jul 29, 2018 at 14:24 | comment | added | Martin Bonner supports Monica | The first Pentium 90 my office got would have been a lot more stable with a cooling fan. It crashed every day or so - which was a nuisance for a machine that was supposed to run a modelling programming which took a week (which is why we wanted the faster Pentium). | |
