No idea, but that's a cute little cooler. I have never seen a Tower cooler on a socket 7 CPU. Personally I'd only attempt this if the case is horizontal. If it is a tower case, I'd be worried that gravity would cause the CPU to be pulled from the socket.

The cooler is definitely cute. 😜

I'm using an IBM 5160 case, which is horizontal.

K6-II in a 5160 case seems like a unique project. I would be interested to see it when done

My advice would be not to glue it, generally speaking, it's a good idea to avoid permanent or semipermanent mods that involve delicate hardware, a much better cooler securing option would be a custom-made clip. You could modify an existing s370/462 clip or make a custom z-clip from a spring rod. As cooler's base is corrugated, a thin rod would fit there perfectly + it would prevent cooler from moving around.

If cooler's contact area is flat, then a copper shim won't be necessary imho, it would only decrease thermal conductivity, unless you intend to protect a soft aluminium heatspreader from possible scratches?

Your ZIF socket may not be designed to handle the mass the CPU will have with that cooler attached, and the awkward angle at which it will pull the CPU from the socket.

I suggest to not glue. Sooner or later you'll regret for a reason or another.

Figure a better method, in the worst case plastic ties are good enough, albeit non professional looking.

As for the additional copper pad, it doesen't make sense on a lidded CPU. You add two additional interfaces to the heath path. In the best case nothing changes, in the worst you decrease the thermal performance.

On a delidded CPU, or on natively naked ones, it may make sense.

I'd also avoid glue.

I'd be more of a mind to use a socket retention brace between the heatpipes, and latch it down that way.

You know, one of these.
