Question H115i , i7 6700k LM up to 92C

[disaseractiv]

Hello, everyone! So the story...
I delidded my CPU about 2-3 weeks ago and the temps was just fine about 60-70 deg in AIDA64 stress test, btw i have my cpu OC at 4.5Ghz and vcore 1.328v in monitoring software.

Now the temps are unbelievable bad. I run AIDA64 about an hour and the temps spikes to 92C, h115i coolant up to 45C. And the thing that i noticed that temps over 4 cores are different. They like 87-82-77-85.

Could liquid metal interface between CPU and IHS dry so fast? I am using Arctic Cooling MX-4 between IHS and AIO which i bought in 2012-2013. Could MX-4 "expire" in tube... and i didn't delid CPU myself i brought it to "custom pc shop" and they apply coollaboratory liquid pro CPU-IHS.

So what can go wrong after 2-3 weeks...? Ty in advice.


i7 6700k 1.328v 4.5Ghz delided
H115i with 2 noctua nf-p14s
Arctic Cooling MX-4 from tube bought 2011-2013.

A ~10'C delta between cores would suggest a poor LM application. Liquid metal does not 'dry'.

I suspect the IHS shifted slightly during installation and you're not making great contact.

MX-4 etc does not go bad, necessarily. You'd notice right off the bat if there was a problem, it would either by extremely dry, or extremely wet (nearer liquid form) if there was a problem.
If it looked the consistency of thermal paste, then it's almost certainly fine.

Fixed that issue! That was caused by my old thermal paste. Idk why but i think it's "expire" somehow. It looked "watery" on cpu. Replaced it with new MX-4 and temps now below 67 in AIDA64
