I've had my lcd steam deck for 2 years. Lately the fan stays on no matter what is happening. Even if I'm not playing a game and sitting at the home menu. No background tasks lr downloads. Rpms stay above 7000rpm and sometimes cuts in and out . Temps are always below 50c for reference. Any idea how to remedy this? Note the fan speed in the photo

I assume this is a pretty easy repair? Rusted nail close to the center of the tire. Noticed it this evening. Bringing it in tomorrow morning.
