You can do it with any delid tool. And also there is solder removal kit. RockItCool

wow I wasnt aware. Considering how I saw him baking the CPU to melt the solder etc I didnt think it was that simple to create a delidding tool kit for it.

I stand corrected

Soldered X299 and Ryzen CPUs should be baked before delidding. There are many SMDs on them so you risk pulling something off when applying the force needed. Mainstream Intel has no SMDs around the die. You just yank it from both sides and it is off.

I would apply the solder removal kit a couple of times to remove Indium rather than scrape it with a razor. Also if you go through all that trouble to delid go all the way and do a direct die mount.

Edit: I did a direct die mount to my friend's 9700K. It was really easy with the tools. It did drop temps ~10 degrees and core to core deltas were much lower. Sadly he got a dud. It wouldn't do more than 4.9 on all cores not for love nor money.

I'd just dial it down, 100MHz is just a 1.9% of 5.2GHz. Maybe tune cache ratio to offset the drop in performance.

Sad reality. Intel binning and sending top SKUs to reviewers.

But yeah, don't use liquid metal man. It will eat into the alu, and possibly fuse itself to your cooler.

Ok guys so I thought YOLO and went for it and I delidded my 10900k and applied liquid metal and what a differnece!!!!!!

Same test as before aida64 with valley in the background my temps are now average:
Cpu package 76 core temps 65 65 68 67 68 70 66 68 62 64

Previous

Cpu package 93 core temps 74 74 78 76 86 93 89 80 81 73
No more core to core delta and roughly a 20 degree improvement in temps!!!!!

This is without letting my liquid metal and kryonaught cure so temps should improve further

You're a brave lad. I wouldn't have risked that, but well done for getting that to work.

Yeah it was a squeaky but moment!!

I used my heat gun to heat the cpu up whilst in the delid tool so the indium was nice and soft and it came off very easily.

The solder is very soft and got most off with my finger nails and plastic scraper.

I then used some 99 percent alcohol and 3000 grit sand paper to sand the die to a nice shine

I removed all the sealant used clear nail varnish on the exposed points and then applied liquid metal.

Its sitting on there loose but I'm not fussed as I can seal it later when I can gran some high temp sealant

Stablity wise I've done 12hrs occt non avx, 2hrs aida64 with valley running in the background no errors

Many versions of prime - you can still disable AVX too.
