Lapping IHS and block

[TheNaitsyrk]

Is this worth it? I have the Magnitude 2066 block and 10980XE I would like to shave off at least 3C from stuff.

 

If so, what should I use to lap the CPU and CPU block? Thanks!

Unless the IHS is very uneven. The CPU might run 1-2C cooler after lapping the IHS.

Direct Die Frame?

Are you looking for something like this?

Direct die is going to better and more definitive since CPU lapping requires skill and is no guarantee depending on the waterblock bowing. EK in particular sells supposedly plates specifically for lapped CPUs.

I went the route of getting a custom machinef flat IHS and the flat EK magnitude cold plate since I had some super wonky core to core deltas even after a de-lid.

I kept the original IHS intact for resale reasons. This is probably a lot harder w/ the 10980XE though due to it being soldered.

Would you say I should lap it myself? Not too hard following a tutorial. I don't get huge core deltas currently btw, but I'd love to drop extra 3C or so. It would put my temps in very comfy range.

i lapped my 2700x and the EK full cover waterblock and i dropped about 20c, i suspect one side or the other was crazy uneven or something prior because i was idling at about 78c on water prior to lapping it so i would never expect results like that for a normal case. used the same tube of thermal paste on reassembly and had tried reseating it prior, so i dono.

 

Also lapping the CPU is fun and a great way to kill some time, i started at 800 and ended at 10,000 grit paper, most people stop at 5-8k grit but i had some lying around so i ran that on there too and damn was that thing shiny

I might do that. Tape sand paper to my desk and apply water and gently sand it in figure of 8.

Don't do this unless your desk is made from glass. It won't be flat enough and you'll end up with a finish no better than what was there before.

Use something like a mirror or sheet of glass.
