add thermal pads to cpu delid?

after delidding and liquid metal pasting my made me realise there is a fair amount of wasted space under the IHS for my CPU.

i was wondering about adding a thermal pad either side of the silicon to connect the cpu board to the IHS.

just wondering if this has been done before? if so wass it worthwhile?

thanks in advance

I don't think you'll see a difference beyond margin of error at best.

Need to consider that this will probably reduce the pressure of the IHS to core so you're going to potentially lose thermal performance if done incorrectly with thermal pads that are too thick.

yeah im going to be careful

ive ordered various pads and a replacement copper heatspreader. i know the copper heatspreader will make the end result kinda invalid as it should reduce temps slightly with just that.

im at the point where ive done everything else to get it cooler. im kinda hoping a few degrees might make the difference.

my coolant is just above ambient pretty much now when the chip is running at 77c for a while. so i figure i need to get more heat into the loop/away from the cpu.

i really dont know how much heat it focused into the pcb the silicon chip is on.
id say it %50ish as half the chips surface is pressed against it. maybe more if you consider all the actual electricity runs on this side aswell. im probably wrong though.
