9700K 4.9 GHz OC + NH-D15 Running Really Hot

[brikn]

I am trying to overclock my 9700K but from the research I've done, mine seems to be running hotter than everyone else. I'm seeing people get 5.0-5.1 pretty normally with 1.28-1.32V Vcore with temps around 80-85C at load, while I'm at 4.9 GHz, 1.25V and hitting thermal limit.

 

Some of the things I've tried:

• Reseating CPU cooler
• Different thermal paste/new paste application (switched from NT-H1 to GC Extreme on 5/28/2020)
• Adjusting tightness of cooler

All the fans (case/cpu) are spinning from what I can see, both in the case and in HWInfo. Just not sure what's going on here and looking for outside input.

 

Here are some resources I looked at when trying to overclock this CPU:

• My 9700k ain’t boosting to 4.9ghz (specifically the comment by Pyromonkey83)
• Z390 & 9th Gen CPUs Step by step, in depth overclocking guide for 9900K, 9700K, 9600K
• ASUS Z390 Quick Overclocking Guide | i7 - i9 | 8700K - 8086K - 9700K - 9900K
• i9-9900K at the Limit | OC the easy way | ROG MAXIMUS XI Overclocking Guide

According to siliconlottery.com, pretty much every 9700K should be able to do 4.9GHz. Even though their table says 1.337V, I'm afraid to go that high because I'm already hitting thermal limit at 1.25V.

turn it off and unplug and open the case and remove the cooler to see if there is a gap where it doesn't have thermal paste, assuming you got new paste to reapply

or maybe your paste is old and needs redoing

also intel's are always hotter

[skannerz22]

use ceramic based pastes as well they are cooler and less likely to create electrical shorts

[skannerz22]

also try using more than 1 program to be sure where it is overheating

try this

All the testing was done post-new thermal paste application before this post. I applied new thermal paste and added a little more than just a dot just to make sure there's good coverage.

[skannerz22]

 sometimes there is a gap missing when you put the cooler on and you can't see it unless you remove the cooler to check how it spread

what type of paste give the full name and code someone else might know more than me

I added it to the post

[skannerz22]

have a look inside speccy to confirm where it is hot as a "second opinion" like a doctor

[skannerz22]

with power mode at high it was at 73c reading this then i put it on balanced and heat went to 60-63c then back to high it was still in the 60s around 63-66c but then jumped back to 73c then back down to 63-66c even on high

 

this is with opera running 6 tabs, 3 cache cleaners in background not doing anything

 

and my thread ripper is a rectangle using a smaller circular water cooler so the edges are lacking metal touching the cooler but the temperatures are still even

 

maybe this can help figure it out for you i don't know

[skannerz22]

if it was multiple cores it would be the fan not being good enough

if the fan for radiator or water cooler,  was good enough you got a fast fan for the cooler then it's intel being crappy versus amd

but then 1 node being hot could end up being program error or thermal paste error

sometimes the cpu can be faulty where an identical cpu with identical hardware you got wouldn't have the issue

 

that's my logic anyway

[skannerz22]

i3 10100 and i7 7700 they didn't design the cpu to be able to be overclocked

but that is not going to stop people pumping more power into it with better coolers and trying to get faster speeds

and i remember linus complaining about the i9 having similar issues where somewhere inside the cpu it's not build for overclocking in some 2018 or 2017 or 2016 video when he was comparing it to threadrippers or something the K series usually supports overclocking at the expense of something else linus said in those videos i can't link here since i lost them but they are on his youtube

but people still overclock using programming

so basically things like this happen where it overwise wouldn't happen because offically like that i3 and i7 intel doesn't support oc but unoffically people still try and if you complain to intel about overclocking having heat problems somewhere they would just say they don't support it and can't help you
