Intel i7-10750H, i7-9750H are very potent CPUs but laptops with them tend to run on the hot side. Did Intel meant H for Hot? Of course you may need some time to cool off from gaming or rendering or whatever demanding tasks are. For casual web-browsing, watching Youtube videos, simple office works, you probably don't need all the computation power, nor all that noise and heat. In case of those H-series laptops switching Power mode to "Better battery life" unfortunately is not enough. The solution I found for myself is to addition to going with the "Better battery life" even on AC, is to reduce maximum processor frequency, let Windows park more cores, and stick to the Passive cooling policy. Reducing max frequency, also may reduce coil whine as a nice bonus :-)
Convertibles like Lenovo Yoga 940, HP Spectre x360 have Processor power management disabled by default. The reason is unknown to me, but necessary adjustments still work, and that's all that matter.
Here comes the usual disclaimer, that whatever you do with your computer is on your own risk, and I am not responsible for anything you get using instructions below. Please make sure you do have backup of your MS Windows registry, you will need it to revert your changes.
1. Make sure you are not running high performance mode in HP settings: In "HP Command Center" select "HP Recommended"
2. Make sure the Power mode is set to "Better battery life": On Windows taskbar click battery icon, select "Best battery life"
3. To enable Power profile adjustments for CPU just download and launch registry file - http://loc2log.ucoz.com/power_management.reg. It will enable parameters discussed below, but it will not set any values - that is totally up to you, how much performance to cut for sake of quietness and temps.
4. After the registry file execution, on in taskbar, right click on battery icon, select "Power options", "Create a power plan".
5. Put whatever you like in plan name, e.g. "Cool", click "Create".
6. On the newly created plan, click "Change plan settings", then "Change advanced plan settings".
7. Locate, "Processor power management" and tweak enabled parameters to your liking.
The following configuration pretty much eliminated heat and noise in my case on both HP Spectre x360 with i7-10750H and Lenovo Yoga c940 15.6" UHD (all for both, "On battery" and "Plugged in"). The Yoga was not as quiet as the Spectre though.
- Processor power management
- Processor performance core parking min cores: 50%
- Maximum processor frequency: 1600
- System cooling policy: Passive
8. Click "Apply", give the computer some time to cool-off, then try some of your "non-demanding" tasks. Adjust parameters as necessary
9. Click "Ok" to keep the parameters.
Now you should be able to run cool and quiet with just switching to the newly created power profile: On the taskbar right click on battery and select your "Cool" profile. Enjoy the silence ;-)
