I did some testing. It has been less hot today, 27 C in my room.
There is nearly no benefit at all of removing the heatspreader. There are only two things I noticed. The cpu is more "stable". Before delidding it would sometimes crash without reason ( I think it was an IMC issue ). Now it seems to work stable. Secondly, temperature goes up more smoothly, this means that heat is transfered more fast to the waterblock.
Im using gelid extreme. I tried to apply metal paste but it wont stick to the die so I gave up. The surface looks like a mirroir once it is well cleaned. Way better than a sanded IHS.
Here some results :
After 40 minutes occt
Delta room temperature - water temperature is only 2 degrees, bare that in mind to interpret the results.
Last year at the same time ( it wasnt nearly as hot last year )
So there is a benefit, I would say 2-4 degrees. It doesnt however help for oc. I tried 4.3 ghz. Even with vcore @ 1.6v it isnt stable. If I could apply coolaboratory on the die, Im sure this would make a big difference. But it wont stick
