When there are no nubs on the socket, they're probably broke of at some point. There is adhesive heat conducting tape which can be used in that case.

Just have a link for my European supplier, but you wil get the idea:

I've seen the tape in different places, but people seem to feel like it's not good for CPU's - not conductive enough?
Thanks!

It's not ideal, but when you're out of other options it's what you're left with.

The P60 was considered insanely hot when it came out, but by later standards its 16W heat output is pretty modest and nothing to make thermal tape break out in a sweat. A bigger issue is the tape at some point losing adhesiveness and your heatsink falling off. For that reason it would be best to use this board in a desktop-style case with horizontal motherboard.

So long as you aren’t fussed about the heatsink being attached to the CPU in a manner that might mean it doesn’t come back off, thermal epoxy is the way forward.

Though back in the day we used the “thermal compound in the middle, four dots of superglue in the corners” technique, that worked well enough and allowed for a gentle twisting off if you wanted to change the heatsink or reapply the thermal compound.

I also have a Batman's Revenge board with a socket that has no tabs and it wasn't broken at all, some of those boards just use this particular model of socket.

Double sided thermal tape works just fine with any Pentium 1 CPU, even with the toasty original P60 and P66. Just make sure you have a fan on top of the heatsink, or at least a case fan blowing air nearby because those get really hot with just a heatsink.

I agree with this.

Second option being to use the paste in the middle + glue on the corners trick as others have said.

If it has to be in a tower, what I would try personally is use one of the above methods while also cobbling some kind of bracket out of some stiff wire (14\12\10 gauge solid wire, like what is used for home wiring) to pass tightly through the heatsink fins and then attach to two of the mounting holes on the board. It's ghetto but it's better than having the heatsink pop off some day and fry the CPU. Unless you do it wrong and it shorts out the board and burns your house down. You know what. Just use lots of superglue. 😂
