Disappointing 7820x temps?

[BWLServers]

Very possible this is the wrong section, I wasn't positive. Watercooling maybe?

Anyways...

Judging by the overclock database I was just looking at (Looks like another user got 4.8GHz on all 8 cores with an H115i in push/pull...) these temps can't be normal.

Just curious if anyone has any suggestions? I'm not new to computers but fairly new to overclocking.

 

Just using Intel Xtreme Tuning Utility, I've got all 8 cores set to 4.2GHz max turbo (only 200mhz over stock clock... no adjustments other than dragging the sliders up from 4GHz) and I'm hovering around 75c under full load. Highest core peaked at 84c. As soon as the system returns to idle, temps drop right down to 35c with the loop warmed up.

I've delidded and applied liquid metal (maybe I botched that? I was definitely cautious about applying too much, maybe I didn't use enough? I got full coverage.)

Using IC Diamond thermal paste for the monoblock on top of CPU, it's also possible I don't have full coverage there.

 

I guess I'm just curious about the first thing I should check. Anyone got any good suggestions? Did I FUBAR something? I know this CPU is capable of more, especially with LM.

Unless you adjusted voltages, its likely pumping more volts into your CPU than needed. Try playing around with the Voltages as well as the core multiplier.

Okay. I've never really used XTU before, does it auto-adjust voltage when I bump up the clocks? I dropped everything to default and I'm still sitting around 65c on average on all cores. Even that just seems way too high for this CPU with the cooling setup I have. Perhaps I'm wrong?

Yes, it does auto voltage.

 

Don't use software to overclock your CPU. That's fine for your GPU but for your CPU it makes a lot more sense to tinker at the BIOS level.

 

I'd max out your OC at 1.25V and see how high your clocks can go on an H115i.

OK, I'll keep that in mind. I appreciate it.

Also, I should clarify. I'm not using the H115i. I've got an EK monoblock with 2x240mm rads. That's why even stock clock load temps are confusing me.

 

This is where I'm at right now. On a 7820x with LM...

What does RealTemp show for temperatures? Same thing?

[BWLServers]

Yep, same thing. I can only assume I screwed up either the LM application or the thermal paste under the monoblock considering I was getting the same temps before I applied LM.

Ah, yes the thermal paste replacement under the lid should definitely improve temperatures significantly. Maybe try re-applying it while following a guide on Youtube?

WOW! Just delidded again and put more liquid metal on (definitely didn't have enough) and temps are down to 45c under load! So much better!!! Thank you!
