Math Co-Processor Question!

[gerrydoire]

I bought a math co for my 286 and my 8088, they both get hot as hell, is there any heat sinks or whatever out there to keep these things cooler?

Couldn't beleive how hot these vintage chips get...

Are you looking for some original parts, or will any kind of heatsink do?

In case of the latter, you could buy some tiny heatsinks for graphics card memory chips. Should be able to stick 3 or 4 of those on a 287.
These for example.

Good to know that they run hot, I should get my 287 tomorrow

You mean like this:

Essentially any old heatsink should be fine. You could even use silicon paste if you really want but the old chips don't really get hot enough to need most of that. Alternatively if you don't mind the noise you can also mod a case fan to blow through the system and out the back.

DigiKey carries a couple of heatsinks for 40 pin DIPs. They're inexpensive and made to be glued on:

But I wouldn't bother--most 8087 and 80287 chips run pretty warm, but not what I'd call "hot".

I agree with chuck, I have an 8087 in mine, never noticed any overheat issues...

The 8087 in my IBM PC feels like its about 106 F

Oh, that's OK then. The trouble doesn't start until 107 F ;-)

I dunno, I've had one fail at 106.9 before...
