So I bought the HP Omen yesterday and after installing my first game on it and started playing it, i noticed that the laptop was getting really hot, so i installed speed fan to measure my temperature and i found that while playing, the cpu was getting up to 90 degrees c , and the gpu approximately 10 degrees lower than the cpu all the time, keep in mind that that's my first good gmaing laptop, so i don't know if that's how it should be, i would appreciate u guys helping me.
(EDIT) Also the first fan is going much faster than than the second one, the first one can be running on 4000 RPM, and the second one is one 150 RPM or lower.
Solved! Go to Solution.

The issue here is the Intel 8750H... Its simply a hotter CPU by nature and the slimmer 15" chassis paired with HP sub-ideal cooling solution lead to undesired overheating..
Your easy fix is downloading INTEL XTU (Here: https://downloadcenter.intel.com/download/24075/Intel-Extreme-Tuning-Utility-Intel-XTU-) and undervolt the CPU by -0.150 (If stable) this should drop your temps to mid to low 80s..Use this youtube video as a guide on how to use XTU: https://www.youtube.com/watch?v=R7OdTmylZNQ&t=218s
Your hard solution is to replace the stock thermalpaste with something better and you will need to undervolt anyway to get maximum cooling..
Its not really hard to do and you will see the benefits right away and for 0$ spent using the Undervolt Method.

Yes, This is all INTEL software and they have a fail safe system so if you screw it up somehow (Which you shouldnt from watching the video) the system will just lock up (You will have to hard reset the laptop) but once restarted it will revert anything you did by itself... So its really hard to mess anything up when the Software wont even allow you to do so, Also this only affects the CPU (Hence Intel Software) the GPU wont be affected at all.
Undervolting is removing unecessary voltage from the CPU. Since CPU manufacturing is not perfect some CPUs need more power than others to run, So in order to satisfy all yields Intel ALWAYS overvolt their CPUs in order for them all to run stable. This excess of voltage is then converted to HEAT which is the main culprit for the 8750H to run as hot as it does.
Removing this excess heat (Thus voltage) from the CPU will allow it to reach higher clock speeds = More Performance since the CPU does not have to thermal throttle anymore, This is essentially what UNDERVOLTING means.

From other users Ive seen the maximum offset for the 8750H is around -0.150mv which is what I am running in my 7700HQ OMEN. This is all CPU dependant though! dont go setting -0.150mv offset right out the bat! you have to test various offsets first.
You can start easy with a -0.050mv and use the stress test feature on the Intel XTU software for 10min runs to find the CPU sweet spot and go from there in increments of -0.010mv at a time.
So my test methodology is:
Select a new Undervolt ex: -0.050mv > Stress test it for 10min > Is it stable?
Yes > Undervolt again by -0.010mv to -0.060mv and Stress test it again.
No > Back down -0.005mv to -0.045mv and Stress test it again.
Please make note that is in NEGATIVE increments or decrements.
Dont overvolt ex. "0.150mv" it needs to be a negative number ex. "-0.150mv" always as you want to UNDERvolt.
And so fort... Until you reach its maximum..
You will now when you have undervolted too far because the system will lock up (Will freeze the entire Windows).
That is basically how it goes, Its a long testing process but very rewarding!! my 7700HQ removed almost 15°C out of its maximum temp with undervolt so I run it all the time now.
