it is possible to delid a soldered on IHS not very smart, and you temps will be worse, but possible.

Very true. Look at this thread.

I am going to see if I can get this expiriment rolling again.

If not, maybe I can get hands on another FX4100. I just got one with bent pins, but after bending back and successfully seating into a socket, its a bad idea to pull the cpu back out due to lessened pin integrity.

would be worthless to pull mine out to try and delid, just to have a bunch of pins fall off.

Someone a while back delidded something like a 6800k or something. Managed to get 1°C cooler idle, and like 5°C under load. It's not that bad, but it's not that good.

#2 if taking the heat spreader off improves cooling, why do the companies have on on there in the first place? wouldn't it save them money NOT to have it?

#3 Are there any specific risks involved other than the obvious possible damage to the cpu in removal of the heat spreader?

I've got an FX 9370 and the temps aren't bad considering the overclock (45C Average under load @5.2Ghz) but as we all know it never hurts to keep it as low as possible so just trying to learn more about delidding in general.

#1) Depends on the series. In particular, recent Intel CPUs have had issues with a gap between the IHS and die. This resulted in temperatures of 5-15C!

#2) The IHS protects the die from being chipped or crushed. Mobile chips do not use IHS for the most part because an OEM mounts the cooling solution and accepts the responsibility of proper assembly. This save height/space and lowers costs a tiny bit.

#3) Warranty voided. Accidental damage during delidding. Crushing or chipping the CPU. HSF incompatibility since you change the height of the CPU.
