If it was a copper core and not aluminum would be more inclined to think it may be ok. Oh and the 1Mb cache versions make lots more heat than Intel Pentiums. 44watt TDP versus 16watt for Pentium 200 MMX. just a comparison....

I was referring to socket 5/7 as a whole i think it was the 166 cyrix chips that got up near 30w was it? There were many. Heck a tillamook at 2.1v 133mhz would only be warm to the touch without a heatsink at all

I really don’t see a problem if the massive heatsink is on or partially covering the core area. It does have a heat spreader. It’s only 44w.

We’ll find out soon enough though it sounds like 😀

I would guess that the heat spreader on hold tops would spread the heat enough to make it less critical if the cooler sits right on top of the actual dies or not. In the 1 meg, it might matter more, as the aluminum heat spreader doesn't seem to be as capable.

Ah, was wrong, it was the k6 233anr.

I guess if it doesn't cover the whole cpu we could get a copper heat spreader since it needs to be taller anyway

In that case you could use thermal epoxy to bond it to the cooler.

Spring clips may be able to be bent also

I want to see what appiah4 says about the fitment first. I would have to bend the clip, I don't want to glue anything to the CPU

Glue to the heatsink. paste on cpu

Hi, it not actually AM2 cooler but CNPS 90 cooler that fit the socket 8

I think it from this thread.
Unboxing a new Pentium Pro processor

Does anyone know how he made that work? That's what I need!

I think he take out the clip, bend it so it does not require too much force when clip to the socket 8 which is lower than the default bracket and then just clip the whole cooler into the socket.

Well, here they are.

The base of the cooler is significantly smaller than that of the PPro heatspreader. That said, I don't think it needs to cover the whole spreader, if the spreader is actually doing its job. This looks like it will get the job done, IF it can be centered on the spreader. That is a big IF, and not one I have tested yet. Coming soon..

@appiah4 - Any news regarding the cooler you've bought?
I also need the same thing for my Pentium Pro 200 . Thanks

To be honest I forgot about this completely, the coolers, board and CPUs are in storage and I will try to get back around to this at some point.. Sorry 🙁

I wouldn't stress in the slightest about the hs not covering the whole area over the die.

Personally, an old party trick at lans was pulling the hsf off my oc'd celeron while it was running q3.

At the time athlons would have burned spectacularly, but the celery didn't care all that much. It would crash eventually but that was it.

There's a thought. Find an old s370 hsf. It'll probably fit perfectly.

Socket 370 coolers don't fit, you need to jury rig a clip, which is the entire point of the problem to be honest.

There are 3D printable Socket 8 to Socket 478 cooler adapters out there and I actually got one 3D printed to test, but I do not have Socket 478 coolers..

Wow, i didn't thought about 3d.
Would you be so kind and put the link to 3d files here?
I happened to own some old coolers and maybe it will fit.
Thanks mate!
