I have a socket 4 board and a CPU that has a heatsink permanently attached to the CPU, I tried to take it off but it's on there tight. Anyway the CPU has the FDIV bug and I have a CPU that doesn't have it but I don't have another heatsink for it. I was thinking of using a bigger heatsink from a Socket 7 or 370 even but the socket on the board does not have clips. How can I permanently attach the heatsink to the CPU? Do I just use thermal paste or super glue?

You can buy thermally conductive adhesives for this purpose, like this one I use; http://www.ebay.co.uk/itm/10g-tube-thermal-co … 0-/200981316375

There are better ones and there are worse ones. Obviously you will need to locate one closer to you, but a search for "thermal conductive glue" or "heatsink glue" will probably yield a result.

Watch out though, once it is on you probably won't ever get it off again.

Well, if I don't glue it on what else could I do to help ensure it won't fall off?

Not much outside of machining your own retention mechanism at this point, though there were heatsinks with a plastic square piece which the CPU sat inside of, the heatsink then clipped on top. I have never seen one for Socket 4 however.

The glue should work fine, all I was saying was that you'll want to be certain you want to use whatever heatsink you decide to glue to it.

Just find a cooler that you feel that will work (be sure to have a fan as these get Hot) and use a little thermal epoxy from Arctic or some other brand with a little dab at each corner of the IHS. Use a small dab half way decent thermal compound in the middle and you are set, I use this method so that if for any reason I can still remove the cooler with minimal effort.

If you are in a hurry or do not have thermal adhesive/epoxy readily available I found a dab of super glue on each corner and thermal paste on the rest of the cpu works well on low wattage Socket4-7 chips. EDIT: Also I just wanted to add from what I have read the FDIV bug usually does not affect anything that us retro gamers and such would do either and I think there is even a patch available to fix it. So if you wanted to use the heatsinked cpu you would be fine 😀

An adhesive thermal pad would probably work. Definitely would if it's mounted flat in a desktop. The lower thermal conductivity shouldn't be an issue with these CPUs. In fact many times back then pads of some sort were used.
