Is the problem because of Windows 11 ? i didn’t upgrade from w10 to w11, it came with windows 11 when i bought it.Welcome to /r/Dell. I also uninstalled and reinstalled alienware command centre, OC controls, and dell power manager. I thought it was a BIOS problem but i have the latest one ( 1.4.0 ) that i reinstalled just in case but nothing changed. I tried using other softwares for the fan control but none of them could even detect the fans. When I start a csgo game I have around 300 fps but after about 20 minutes it drops down to 150 fps and the fans don’t seem to start running faster.

My alienware command center looks very basic and lacks features, my dell power manager doesn’t have thermal management, and even though i can control the fans in the “fusion” section on the awcc, well when i put it at 100% the fans are actually not at their max at all, i would even say far from the maximum since it’s not very loud, and it’s sad because i feel like my pc is kind of restricted from its full potential and power. I don't have the “G” key and I'm unable to activate the G mode. So I have a Dell G15 5515 Ryzen edition with RTX 3060 and Windows 11, and the problem is that my pc seems to be missing some functionalities which i should normally have.
