Hey, so I’ve been having this really weird issue with my Acer Nitro ANV15-51. The GPU fan randomly starts running at full speed even when the laptop is basically idle. Like, I’ll just be sitting there with nothing open except NitroSense, and suddenly the GPU fan kicks in like a jet engine, then slows down, then speeds up again, then quiets down and it just keeps doing that on and off for like an hour. What’s strange is that the temperatures are totally normal when this happens, and the GPU itself isn’t even active or being used.

There’s nothing heavy running in the background either. It’s super distracting and doesn’t make sense considering there’s no reason for the GPU fan to be acting like that. I bought this laptop around 10months ago and I barely use it just once or twice a week for a few hours each time, mainly for college projects using stuff like Django and other Python tools. I only gamed on it once, like seven months ago, and there aren’t even any games installed anymore. All I’ve got on here is Microsoft Edge and some development-related packages. I’m just trying to figure out what’s causing this because the fan behavior doesn’t match what the laptop is actually doing. If anyone’s experienced something similar or knows what might be going on, I’d really appreciate the help.
