Apparently, the only thing is now stopping me to use it, as daily driver is unable to control the fan. I am using Gigabyte Aero 10th Gen Intel Core i7 with NVIDIA GTX 1660Ti card. I was surprised when everything was working fine out of the box. Currently, I am also using Fedora where I control fans through writing bits on EC using <a href="https://github.com/jertel/p37-ec" target="_blank">c program</a> uses ec_sys of Linux. My laptop gets pretty hot. I don't want to set a limit on the CPU frequency. I came to the conclusion that my laptop's fans cannot be controlled through ACPI (or I am not capable of). Not only that, but I explored and tried all possible solution such as Arch's documentation or any other code regarding fan control. I hope I will not be disappointment in this forum.</div> <div> </div> <div>I would like to also request you hide the email address if this is posted publicly. Thank you for the time and consideration.</div> <div> </div> <div>Regards</div> <span>Raz</span></div> <div style="font-family: Arial , sans-serif;font-size: 14.0px;"> </div> <div class="protonmail_signature_block" style="font-family: Arial , sans-serif;font-size: 14.0px;"> <div class="protonmail_signature_block-user protonmail_signature_block-empty"> </div> <div class="protonmail_signature_block-proton">Sent with <a href="https://proton.me/" target="_blank">Proton Mail</a> secure email.</div> </div> </div> </div> </div> </div></div></body></html>
