    so what if I just purchased the IHS and didn’t lap my die? The added height of the IHS should certainly help with temps right? Then I wouldn’t need to do the tooth pick mod on the retention arms.

    Stock 8th gen intel ihs is ~3mm in height while the custom ihs is 4.37mm.

    lower than 8th gen die height that is hella risky. but damn great job brother!

    custom ihs in itself doesn't do much. the silicon height or w/e material it is prevent heat transfer and that needs to be reduced for maximum heat transfer hence the reason for liquid metal between IHS and die. sanded down die would mean more benefit.

    I know a sanded die certainly helps a lot. But these laptops have very little pressure put on the GPU and CPU from the heatsink retention setup. So when people run the paperclip mod or toothpick mod they see like 15-20c in temp reduction.

    The taller IHS will certainly help. I’m just trying to gain around -10C better temps.

    That's another project, long term effects of LM on lapped die, hehe.

    But in all honesty, I was more worried about cracking the die after shaving so much off. As 4.37mm ihs does put a good amount of pressure on it, hence why I removed the c-clips altogether.

    That is some extreme performance in a laptop. And it is solid 24/7 stable. I am running a very similar undervolt as you are. But you’re running a 9900K. So this is all extremely impressive. I’m getting to work next weekend on mine. I’ve got to order some stuff.

    So long as it's even pressure you are good.

    Well, it's CBR15 stable, lol.

    Now imagine if a decently binned 9900KS was given the same treatment ;)

    by default 9th gen cpu is thicker than 8th gen so it provides better pressure in 870tm but thats also because the thicker die which is the worst part to be thicker. so he got the higher IHS to replace height for sanded down part. you could try solder shim onto heatsink that wouldnt be much
    what is your load voltage? cpu z showing 1.2v for 5ghz.

    During a CBR15 pull on 5Ghz at -185mV core VID is ~1.225v
