Too high CPU temperatures on gaming.

[Campe92]

If can help, i had the same problem on my Hp dc0030nl with i7 8750H and GTX1060...i solved when i reduced the max cpu energy from 100% to 99%, (as you already don) + in general battery options i switched on "better performance" instead of "maximum performance"...i tried to reduce the cpu energy from 100% to 90% too, and with "better performance " setting, the maximum CPU Temperature i had on BF5 (All medium setting, 90Fps) was 68 °C and GPU was something like 74 °C...the fans never started, never had a drop frame or something like that could compromise gaming experience.

Room temp was about 23 °C,  and in idle i have CPU at 40/41 °C and GPU at 38 °C (with 99% cpu power)

Hi,

i have an hp omen 17. i7-7700-HQ and gtx 1060. my laptop has been throttling recently. my gpu is fine(maybe) at 75 degrees buy my processor is 50-60 at idle and reaches 90s when im gaming(even when it is at 50% laod). which guide did you use to apply thermal paste? is liquid metal better than normal thermal paste? 

any tips would be appreciated. btw im also going to undervolt it soon. and ive already turned turbo boost off.

First of all, i7-8750 reaching 99c is normal in all laptop.  Nothing you can do about it much because of the 6 cores  max at 3.9Ghz Turboclock.  The cheapest step is using XTU from Intel website and undervolt it for -0.125V to -0.150 V .  This will keep the CPU at turbospeed most of the time 3.9Ghz during gaming and ocassionally throttle to 3.3 Ghz. Very respectable, Other system like Dell XPS 9570 only can reach 2.x Ghz when gaming because of VRM throttling. 

Just Undervolt and do whatever you want without any noticable Lag in gaming if you have 1060 or 1070 max-Q.  If you have 1050, the GPU is already slow and CPU cannot help much as long as higher than 2Ghz.  For reference, I have 1070 max-Q with i7-8750H got FPS for most game as fast as regular 1070 in this OMEN 15.  The cooling system and the bios is really good.  It still runs hot but only the CPU which I never concern too much.  If it is the VRM or MOSFET that overheat, It will kill the system in long time.  Intel CPU is very reliable and runs at 99C all the time will not kill it, if it is NVIDIA GPU that runs hot, I will worry because GPU failed way more often than CPU.   This 1070 max-Q usually hover at about 70-75C which is nothing to worry about. 

You can open the heatshink, clean and reapply good coating in all components around the CPU die to protect it from Liquid-metal (metalic will burn your SMD capacitor, resistors, etc.).  You may get 4-5C drop in high load gaming but will not increase performance much and risking you kill the whole system. I do not recommend it, just undervolt and happy with 3.3-3.9Ghz even at 90-98 C, the rest of the system are still cool.  The cooling  is super, it covers  GPU, CPU, VRM, GDDR very well.

You got lemon.  CPU 100% load should about 90 C if you use liquid metal. With other paste will be about 97C,  if you got 74C than your software is not demanding enough.  Try intel XTU benchmark or runs any Molecular Dynamics Simulations at 12 thread, it will shoot higher than 90C for sure.  lower at -0.150V it will prevent thermal throttling but power throttling still happened.

This is a great explanation and is how my laptop is running. I use AFI Afterburner to control the undervolt by creating the flat line in the power curve(ghz) and throttlestop to do some final optimizations. With throttle stop I don't control over/undervolting but there's a setting which prevents your cpu from throttling the performance when it's high 90s temperature. I do not limit turbo and all is good. This laptop does need to throttle when GPU is above 81C but CPU temperatures up to 99 seem to be no problem in use nor by Intel specs listed on the internet. I have a 1060 btw. I also set my energy performance at 97/97 min/max probably because my undervolt is set a bit high. My GPU temperatures are 73-80 and averages 75-78, running my favorite fps games with high framerates.

Hi all and thanks for the replies.

As i said in the previous post, i'm limiting the cpu power at 99% and i'm using the best battery power profile instead of maximum power profile. The system is good but since i'm using ideally the half power of the system, i'm still trying to find the best solution in order to achieve the better performances with the lowest temperatures.

I have a question: if i use the best power profile and the cpu power settings on control panel are set on 100% (with ac current active), the frequency core is firm to 3914 Mhz.

If i lower the cpu power to 99%, the frequency core goes firmly to 2108 Mhz.

In my mind, ideally, the frequency core have to change according to the tasks the cpu has to manage, so, it has to be really low when you are in idle (lower than 1500mhz for sure), and grow when you ask something to the cpu.

Do someone know why this not happen?

The cpu is the i7 8750H

[JhonHamann]

It is clearly right 99% from max core 2.1 Ghz.   By ordering windows at 99%, it disable the turbo boost of 3.9 Ghz in all 6 cores or 4.1 Ghz in 2 cores. Nothing is wrong with your 99% with automatically disable turbo-boost. 

[Campe92]

Yes, but my doubt is: is it normal that in fact there are 2 states, turbo on or turbo off? In other words, why have i to manage myself the turbo state, instead of the pc? why the pc doesn't deactivate the turbo, and so, lower the core frequency when the task are basical?? i think it's so weird that my cpu stays fixed to 3.9ghz when i'm on google

[JhonHamann]

That's the point. Most people want the most performance and turbobooost is at Max with 3.9 GHz. If you want lower you have the choice. You loose about 60% extra performance without turbo. And temp in CPU at turbobooost is still safe although 90+C in most cases. But with sustains 1 day load it hover at 80c at 3.5 GHz. Very good cooling for 6 cores. Other brands like Lenovo may be cooler but less performance in sustain load.
