Ok i will try tomorrow. But i do not understand way msi motherboard has such a high stock voltage ? It's not good at all.
disable xmp and see if the voltage differs.


Fill in your system specs verbatim.

Damn that is quite hot. I remember my first 5820K was able to do 4.3GHz with ~70C max during Prime95. Same Noctua D15. Not much luck with the current one though.

Hmmm . I have the M5 no issues. I've heard some voltage issues regarding your mobo but not the M5.

I got Z370 gaming pro carbon eider no problems,actually is a performance mobo,10 phases,nice features,rgb :D

Results after undervolting CPU at stock frequencies.

Bios settings CPU Core Voltage @ 1.060v, memory 3333MHz CL-16-18-18-36 @ 1.35v. What you think guys are these temperatures good for noctua NH-D15S cooler ? Or i need to replace thermal paste and check what's happen.

Temps were fine where they were... 20c less is better! Seems like its using the right voltage now that you set it. :)

Max temp ~ 63C when runing mafia 3 on 1.060v this game is quite cpu hungry.

You should keep undervolting until you get a BSOD. You'd be surprised how far you can go. I've got a -170 offset on mine. lol (again, I'm on Kaby Lake though). edit: Wait, you've got low 60s. I doubt you can do better. That Noctua lives up to the hype it seems.

I have to be honest, I still believe there's something wrong... cannot believe those temps at such a low core voltage. Check if your fan cooler is installed correctly, and which kind of thermal paste you are using...

Check fans case rpm,check dust filters,add more fans if not enoough,apply good thermal paste,default bios,set only xmp

XMP on my Z370 Gaming Pro Carbon dont affect Core Frequency or else.. is just sets the ram to 3000 mhz,goodluck

Along as you're not thermal throttling; the temperature doesnt matter on these chips. They operate fine at 95C.

now that you got the temps down make sure its stable and check for whea errors in event log. if you have any bump the voltage up slightly then clear the event log and see if anymore re appear. if you dont have any now go ahead and see how low you can get the voltage before you get a whea error then bring the voltage back up a bit tell you dont get anymore . you will get whea errors before a bsod in most cases. they also cause random fps drops in games so its always good to make sure you have non.

Just be careful with the whea errors in Windows 10. Every other one I've gotten has always resulted in the registry config database corrupted.

good point.

make sure to run sfc /scannow in command prompt as administrator after using this method.

OP you may also have an improper contact area between cpu and cooler; check with a razor blade the flatness of each contact area

the area can be convex,concave or "flat"; even is "flat" a proper lapping increase the direct contact area by eliminating all small defects (which are filled with thermal paste otherwise) and reduce temperatures with a few degrees

there are a lot of tutorials about this procedure ...

and how much paste you used... paste is to fill out the gaps not to have a layer of it between cooler & cpu; no matter how conductive is the paste you shouldn't have a lot between as direct contact is best to heat transfer

i almost have no paste between and my temps are low; my cpu was hot also but i lapped both contact parts and gained at least 5°C; i applied a thin layer with a razor and squeeze out all excess before fixing the cooler...

Again, i dont see a problem.... not sure why others are...

Mmm...
And.... what about this... :

Hey man. My 8700K runs at 33-37c stock air cooled on a D15s. Gaming it never exceeds 52c. I have it overclocked to 4.7 with no temps that hot. Something is not right.

That's probably not true. All depends on games which ones you are playing settings etc.

Today i replaced thermal paste to Arctic Cooling MX-4 and it performs very close to Noctua nt-h1 there are maybe 1C difference at best. Cooler is mounted properly and fan direction is right case fans runs at 700 and 620 rpms.
