That's normal, probably a background service of windows doing something that causes the load to quickly jump up would be my guess. Both my old soldered Core 2 Extreme QX9650 and delidded i7-5775C do it.

Shawnb99 I'll see what temp I get when I reapply my paste, finally the back-plate for my WB is in stock so I'll wait for that first before I decide if I'll redo the delid myself.

Hi,
I wouldn't redo it unless it goes wonky you're just asking for trouble

You already have a copper cap just lap the top flat and it's copper on top

Take a picture of the top of the cpu cap first before lapping it just for kicks.

Hi,
I do visual already posted of a decapitated 7900x SL did
If it goes wonky after a little while you'll know why don't bother contacting them over higher than now core temps it's a waste of time all they will say is it's normal

Ah ok. I wasn’t entirely sure what silicon lottery was before. I just found out that they provide ‘binning’ and delidding services.

My 9900k under direct die custom loop at 1.285V turbo LLC goes from 30 idle to 65C under load. It was going up to 77 before but then I switched from CLU to konductonaut and removed the plastic washers, which lowered the waterblock by 1mm. Check hw info to make sure that you’re not getting any voltage spikes along with that temp increase due to background processes. If you’re idling, then you might be right about a bad interface.

When I delidded the 9900k, I had to polish the die using metal polish (gently) to get it to a mirror shine. If you look at your die and it’s scoffed, that might have an impact.
Hope that helps

One thing I’m assuming - you did apply a conductive metal TIM between die and IHS, right? If not, I don’t think you’re doing yourself any favors.

I had to scrape it with a razor blade to get some crud off heavy burns is probably accurate description almost thought it was LM reaction to the nickle or something ?


I really doubt it. Last cpu before the delidded 9900k was a 4790k. I ran it as a direct die with the same waterblock. There weren’t any burns and I removed the block and replaced it three or four times without having to reapply the CLU. Temps were fine.

Did the same with my 9900k and got the same burns on my nickel waterblock, and my cpu. I had to repolish the die. Rockit cool suggested removing the plastic washers to get it 1mm closer, and I’m getting a much more solid connection now.

Yea I doubt that it was a reaction. I think it was too much gasket.
