Problems with the cooling system and cpu frequency

[yago85]

Thank you so much for EFI! Please clarify how your cooling system works? On my Dell Precision 5550 with i9-10885H with a low load, the fans work intermittently, turn on and off very often, and at a temperature of 45 - 50 degrees Celcius they reach 3375 RPM. Does it work the same for you or more smoothly? I also noticed that the maximum CPU frequency does not rise above 3.8G, and I tried different options both with and without undervolting. At the moment I am working with the parameters as in the screenshot.

My CPU is the i9-10885 as well, but fans rarely kick in unless the machine is under some serious load. However I have not seen the frequencies above 3.8GHz either; so it's likely an issue with (not having) an optimised CPUFriendDataProvider.

Happy to have a play with it when I get some spare time in the coming days/weeks unless you want to submit one yourself for testing? ᐧ

I'm also testing different options at the moment. Also, I still haven’t been able to figure out the fans, so I’m solving this problem with Macs Fan Control. But when using this application to adjust the fan speed, for some reason they stop responding to changes in the display brightness key and the battery charge indication freezes in one position. Unfortunately, this is my first experience with open core, so I’m moving very slowly so far))

With latest CPUFriendDataProvider I have managed to bring down the temps considerably, fans do not switch on now in macos.

Also, for those who wish to push their system further, there's a few modded heatpipe chambers out there on the market for the 95x0. Anyone who has tried one can report back with their results :)
