Undervolting the CPU - overheating HP Omen 15

[mdmh84]

Hello HP Community,

My new HP Omen gaming laptop with a Intel® Core™ i7-8750H Processor is seriously overheating while playing demanding games. I installed (CPUID HW Monitor) and saw that some cores were reaching the very high 90's. The chassis become uncomfortable to touch because of the heat, even with a cooling pad underneath.

I assumed that by disabling Intel Turbo Boost I can reduce temperatures. By default my machine is running over 3Ghz all the time even when not gaming. Doesn't this effect my CPU's lifespan? And by disabling Turbo Boost I'm not really getting my money's worth, am I? (note: I keep my power plan on recommended when plugged in, not best performance)

So I 'm thinking that maybe undervolting is the solution. I've never tried this before so need some help. I've found video tutorials online (and on this board) and many people seem to have has success lowering CPU temps using this technique.

I downloaded and installed the Intel Extreme Tuning Utility. However, the "Core Voltage Offset" parameter is missing here (see snap below), which is what the tutorials instruct you to lower by -0.050mv increments. 

Other people use ThrottleStop, but this seems much more complex to me (cache needs to be lowered aswell?).

Plus, I understand that these setting aren't permeanent, so after each cold boot I will need to configure everything again?

Not sure if i should be playting around with undervolting if I don't know what i'm doing, so I'll obviously be doing more research and of course would greatly appreciate any help here. Thanks!

  Heat buildup can cause problems for any laptop (notebook). The most common cause of overheating is the accumulation of dust inside the laptop.

Let's perform Windows Update and HP Support Assistant:

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

1. To open HP Support Assistant, double-click the HP Support Assistant icon .
2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
3. Click Check for updates and messages to scan for new updates.
4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
5. Click the update name for a description, version number, and file size.
6. Select the box next to any updates you want to install, and then click Download and install.

And, also update BIOS: Follow steps from the link: https://support.hp.com/in-en/document/c00042629

Thank you for the reply. My Product number is: 2RJ30LA#ABM

My machine is a month old so dust build up should not be the issue.

Windows is updated, HP Support Assistant is installed and all my drivers and BIOS are up to date.

Does HP recommend undervolting as a solution to reduce CPU temperatures? Since the method utilizes third-party software, I assume not. As I mentioned before, some CPU cores are reaching 98 celcius while gaming. Is this normal?

@mdmh84

Reaching 98 celsius is not a good sing,

• Have you tried uninstalling the game and checked the computer heating issue?
• Does this happen with other application or software?

Keep me posted for further assistance.

undervolting is compltely fine. it might take a while for you to get the setting that suites your machine as its an itterative procedure. try out different settings and also try not to push the machine too far as im assuming you want a framerate. also repasting could be an option to consider 

[mdmh84]

@Rohan98, thanks for the reply. Using the Intel XTU app I don't see the "Core Voltage Offset" variable, which is what most tutorials play around with. What are the alternatives.... or is Throttlestop reliable enough?

@mdmh84 

Have you asked Intel why "Core Voltage Offset" is missing? They would know more about XTU than we would.

[rohan98]

Throttlestop is reliable for sure. Gives a lot more functionality than XTU I believe, could be wrong tho, havent tried XTU ever

I did try posting on Intel processor forum, but there seems to be very little activity there. I did only ask there, however, if anyone coiuld explain in laymans terms what the following turbo boost settings do (under power options). So far haven't got a response.

-enabled

-disabled

-efficient enabled

-efficient aggresive

-aggresive at guaranteed

-efficient aggresive at guaranteed

When turbo boost is disabled temps do seems to be kept lower, which makes sense I guess as the CPU is only operating at base 2.2Ghz frenquency,  Not sure what the other settings do, and which one is best for gaming.

Gotta love those support assistants then fix youre product im using hp omen 15 dc000nu reaching gpu -80 and cpu 100 cel under heavy gaming out of the box when I got it + youre information is completly irrelevant to this guys question ( in short undervolt it from 45 to 35 if ure using  i78750 H you will see better thermals for 10% performance reduction that means in cs:go you will drop from 280 fps to 252 fps ultra settings  assuming you are using the gtx 1060 +++ cards. Also keep in mind that if the ambient temp is above or around 30 cel this will impact youre thermals alot. Also this 8th gen INTEL CPU runs hot keep that in mind 90 ish + is not great but not terrible . Literally no point in repasting after 1 month. 
Every time I read what the hp supp staff says I have a good laugh. BTW fix youre hp support assistant (new version) and update ure drivers for windows 10 version 1903 already lmao. I hope you read my comment before its deleted 🙂
