I just picked up a very nice Micron VL486DX-486 66Mhz desktop. Doing some cleaning and testing I touched the passive heat sink on the CPU and it was very hot. I thought of a case fan but there just isn’t any room so I thought of a cooling fan, but would need some kind of adapter. Looked online and didn’t find any for a socket 2 and looking at the board, couldn’t find a power source on the mother board for one.

I’ve never actually touched a heat sink on an older CPU, I know that it’s subjective, but is really hot to the touch normal?

You can search for 486 or socket 3 heatsink or cooler as well, as they are all the same. I got my 486 coolers for about £5 each last year, though I was looking for a few months.

Yes it's normal. My DX4 Overdrive without a fan gets scorching hot to the touch.

As for fans. If you don't mind being a bit ghetto, you can get a small Noctua fan and ziptie or epoxy it down to the heatsink. Works just fine. Many of Noctua's smaller fans come with adapters for molex power and low noise.

Yes you can add a fan, zip ties do work but better if you figure out how to perm mount the fan. check this topic: Intel 486 DX4ODPR100 runs very hot

Hate posting a reply and have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. 🤣 Second computer a 286 12Mhz with real IDE drive ! After that came 386, 486, Pentium, P.Pro and everything after....
