thermal throttling CPU (i7 8750h)

[Filip94]

Hello, couple of weeks ago I bought a HP OMEN 2018 (Procudt id: 4TU51EA#BED) and im having thermal issues.  That same day I installed Battlefield V from a friend and tried it.  It was running fine but it was really hot at some point. I've installed Intel Extreme Tuning Utility and started to monitor the temperature. It seemed that the CPU was always running at 3.900+ MHz and thus it was overheating. I even tried undervolting but it did not seem to help.

Then found a thread here on forums (https://h30434.www3.hp.com/t5/Gaming-Notebooks/HP-Omen-15-2018-CPU-thermal-issues-fan-noise-solved/t...) and it HELPED but only when the laptop is on battery, as soon as I plug it in it starts to throttle, thermal and power.

Can anybody help me with this. Should i undervolt it? Bios update? Im really stuck. Im even considering buying a cooling station (Coolermaster ergo stand III). And in the end, is this even a problem, is it normal for a CPU to be this hot when there is no need for it to run that fast or hot?

(will provide 2 screenshots from Intel Extreme Tuning Utility)
As you can see, on hourly, after playing for about 40 minutes, it was very nice, temperature was about 60 to 70. But as soon as I pluged it in, it started to throttle. You can see that every couple of minutes, turbo boost goes on and spikes all 6 cores to 90+ celsius and then goes off and again on in couple of minutes. 

Any help is welcomed, thanks in advance!!! Regards form sunny Croatia (dont worry, its not that hot to be a factor in this)

And this, maybe im overreacting, but why does this happend. CPU is under 20 % (IM on Youtube and WhatsApp) and the CPU goes to 6 cores and 3.900 MHz for about 20 seconds and spikes the fans and temperature.

@Filip94 Welcome to HP Forums Community!

I've checked the product specifications of your device, and I see that you've got an Intel® Core™ i7-8750H that supports a Tjunction of 100°C (which means, the device should work fine until it reaches this level of heat), that said, you may want to follow the below steps to reduce the heat from your device, though the cooling pad is a good idea, there's a lot more you can do:

Step 1: Removing dust and lint by cleaning vents

Most notebook computers have vents located around the case to allow air to flow through the case. If these vents become clogged, or if heat-generating parts become covered with dust, the fan cannot cool the components properly, because the laptop is hot and overheating becomes a problem. Lint and dust accumulation prevents air from flowing around the cooling fan blades and causes the fan to work harder and the laptop to get hot. If there is dust in the vents, you should clean the laptop by blowing out the dust from around the fan and heat shield. This prevents dust from accumulating.

It is not necessary to open the notebook (laptop) to clean out the dust with the canned, compressed air.

(By the end of this article all the issues should be resolved)

If the device is overheating, you have a burning smell or any such issues, please let us know so we can look for repair options,

however, if that's not happening, the device is bound to heat up when high-performance applications are being run on it.

Let me know how that pans out,

Hello and sorry for a late reply, im on vacation. 

I have managed to find a canned compressed air and cleared the vents intake and outtake air (although i tought did was not necessary because the laptop as I said is only couple of weeks old. 

It did not affect the temperature, laptop was still hitting 97 C when turbo boost was on. To simplify the story here, I am aware that this CPU was built for this but the temperatures of bezel under the sceen get so hot that it makes me feel uncomfortable to play for several hours because of the heat. 

Now the question i have for you is this. As i said in the first place, I thing that the problem was with the Intel Turbo Boost (ITB) affecting all 6 cores and pushing them to 3.900 MHz for no reason (given that under battery ITB does not go on and because of that the heat stays in really comfortable levels). I found a software with I believe you are familiar with. ThrottleStop has an option to disable Intel Turbo Boost. I did not undervolt it or overclock it, i just simply ran the software and disabled Intel Turbo Boost and the temperatures where amazing. GPU was on 100% all the time now but the temperatures never exceed 82 C on GPU and CPU. Only con of this is when there is a really big need for processing power, it glitches for a second.

Then I went online and found that Intel Turbo Boost was only supposed to activate when CPU was hitting 100%, that is not the case with my laptop. As you can see on screenshots of Intel Extreme Tuning Utility, Intel Turbo boost kicks in when all 6 cores are on 60%, i dont know why is that.

To finalize: Is this normal, the continuous "kick in" of Intel turbo boost, is it really needed by the laptop?

Second question is: Throttle Stop, is it safe to use this software and is it safe to disable the Intel Turbo boost on that software?

(p.s. there was a drop of FPS while gaming, about 5 to 10 %, but there was that glitching witch was not that bad, it only happens when there is really big need of processing power, when CPU hits 100%, but as you can see on that hourly screen shoot that only happens few times on hourly basis.) 

To conclude, I am willing to sacrifice the few glitches per hour and the fps drop of 5 % for a comfortable average temperature of 75 C.  But it this affecting the laptop, am I messing up my CPU with this?

Thanks Riddle.

And another one, Is there a software where you can change the setting for Intel Turbo Boost, to make it activate itself only when there is really a need for it (lets say 95% CPU utilization is that threshold ). Is this possible?

[Riddle_Decipher]

@Filip94 The laptop GPU & CPU in all HP devices are system managed and it's designed to automatically kick-in the throttle when needed, as you've mentioned it activates after 60%, that seems to be the limit set for it and there are no ways or options to change the same.

For the 2nd question, I must let you know that HP doesn't recommend using 3rd party software, hence if that's something you like, you may install and use it at your own discretion, although, Intel Turbo Boost is from the manufacturer of the CPU and hence an application we would suggest using instead (make sure to install the latest version via the Intel website to avoid glitches).

Lastly, CPU Throttling is not something we recommend as it may damage the cores of your CPU/GPU.

to reduce heat becaus 8570h and 8300h ( the one i have) gets hot a lot i have undervolted mine ( doesn´t damage the cpu ) and you can get  up -10 degrees Celsius for doing that , you can use intel extreme utility or throtllestop ( i prefer throttlestop).  i bought also a cooling pad no mater what ppl says a cooling pad helps reducing the heat even further when pc is plugged in
