HP Omen - Overheating

[StevZak3]

Iam gonna follow these instructions and do the stress test, and hopefully my cpu won't reach the 90 degrees agian, will update you guys after finding my maximum undervolt and trying to play the game again.

(UPDATE) While testing, the cpu temp can reach 94 degrees sometimes which kind of scares me.

[StevZak3]

So i passed the first first stress test with undervolting by -0.050,  but is it normal if it sometimes hit 90-95 degrees in the middle of the test, and should i keep undervolting it by -0.010 aslong as i passed it?

(EDIT)- Also forgot to say that i undervolted it to -0.150 off the bat and my laptop was working fine, should i just keep it on -0.150 without testing?

Hope someones responds so I know what iam doing is good for now and thanks again for helping.

Dumb question but did you APPLY the undervolt? because you can select the offset but it wont do a thing if you dont apply it.

If you already hit -0.150mv you should be seeing a HUGE improvement in maximum temps. 

[StevZak3]

Yes, i applied it but i didn't stress test it with -0.150, only stress tested it when it was -0.050 and it was going up really high still, so iam gonna run a stress test on -0.150.

Go for it!

The idea is to reach the maximum anyway so you might as well do a big jump...
As far as going over -0.150mv? the returns diminish as you go forward and system instability might be more common. So if you hit -0.150mv and run stable? that is about the top you would want to consider running. 

IF its still hot then its probably another issue, Since that big of an undervolt should in theory drop +8~10°C.

Thank you so much for the help, after undervolting it by -0.150 V, iam playing right now and my cpu temp is on 79-83 degrees , and my GPU is on 77-80, I hope that would be good enough for long-period gaming.

Thats great! Glad it helped.

As a tip; You dont need XTU to be running all the time in the background! once you hit apply a second process in the background will be created so even if you close Intel XTU the undervolt will still apply even after you put the laptop to sleep/hibernate..
As a common practice you should open Intel XTU after a restart to see if it correctly started the background process again..
You will see the -0.150mv offset applied on the right corner of XTU, If isnt applied the offset number will read 0.000mv. 

To improve cooling even further you can also replace the thermalpaste on the laptop with something like Thermal Grizzly KRYONAUT (Thermal paste not Liquid Metal) but I would wait for the 1 year warranty to run out as I do not know if it can void your warranty by replacing the thermal paste? Hope someone would chime in on this subject.. I would think replacing the thermal paste should not void any warranty.

Hello again @Photoray002 , you helped me out with a previous problem, thanks for that. I am having the same issue as the OP with my HP Omen laptop (dc0006la). 

Running games seriously heats up my CPU, get's upto 98c (using CPUID HW Monitor) , and the laptop chassis becomes almost too hot to touch. I purchased a laptop cooler base, but this didn't make much of a difference.

So I started investigating about under-volting, and learned that the i7-8750h is a usual suspect prone to overheating and on youtube I can see that a lot of people claim to have had success lowering  CPU temp using XTU.

So I downloaded XTU. The tutorials on youtube (like the one linked in this thread) instruct to lower "Core Voltage Offset". This parameter, however, is missing from my version of the program. Appreciate again any advice!

Following up, I've been reading that under-volting may not necessarily be the only solution for high CPU temps.

I've learned that Intel Turbo Boost can be configured  thru advanced power settings with"Processor Performance Boost Mode" unhidden (thru regedit). But I can't find much information about online about each option:

-enabled

-disabled

-efficient enabled

-efficient aggresive

-aggresive at guaranteed

-efficient aggresive at guaranteed

This appears to be much less hassle compared to undervolting since these configurations are embedded in Windows logon and there is no need ro run intel XTU or ThrottleStop at each bootup.

I'm wondering which is the best configuration for gaming on the Omen....?

All,

Have been struggling with multiple HP Omen builds. but generally like the feel of the hardware, so went for the 1070/8750H after my 1050i /7700HQ.

Great performance, like the new somewhat less bulky feel of the laptop, but again... CPU on average running at 93 degrees, with throttling and other heat issues. 

Tried undervolting with the Intel utility. Got unstable results and no massive improvement on the heat issues.

Saw the tip of changing it straight in the BIOS under CPU voltage settings and set it to 25W. That shaved of 11-12 degrees. Combined with a laptop cooler, i can run Assassins creed odessey for hours without the cpu exceeding 75 degrees! 

This seems to have solved it for me at least.
