Can't get laptop fans to work at full speed.

My computer is a local rebranded version of Tongfang gk7cp0s, rebranded version: https://www.monsternotebook.com.tr/tulp … -t7-v19-4/. This computer has 2 fans, cpu and gpu.
I have rtx 2060 mobile and I'm using nvidia drivers for it. Everything runs smoothly, but I have one issue. On my laptop I have a button which when pressed sets the fans to "turbo mode". Pressing this button does nothing on linux (Arch and ubuntu), works correctly on Windows (when the necessary proprietary driver is installed). I have tried to use lm-sensors, fancontrol, laptop-mode-tools to detect and configure my fans but none of them seem to be able to detect my fans. sensors (after # sensors-detect) does not show any fans. Is it possible for me to get this "turbo mode" button work, or get os to detect and configure fans?

PS: Both of my fans are working, but at low to mid speed. When I try to open a demanding program like a simulation or any games, fans don't speed up as much as they shouldi resulting in my pc overheating.

Try the acpi_enforce_resources=lax kernel command line parameter.

Re: Can't get laptop fans to work at full speed.

Thank you for the reply. After setting the kernel parameter, nothing changed. I ran sensors-detect again, and still there weren't any fans showing up. I tried acpid, fancontrol, nbfc(didn't have recommendations again) and there was no difference. The button I mentioned doesn't show up on acpi_listen as well.

EDIT: I should also mention that there is no way of controlling fans or power management in the BIOS screen.
