So yeah, looking back at that one thread I made I got this laptop two months ago. It's an HP 15 Notebook PC. The other day the fan on the left side started making these strange noises. It sounds like one of those portable foam fans. It's not too loud, but I like having a quiet laptop like it was before. There's no way it's been overheating. I feel under it regularly and it feels fine. I updated Windows with the recent updates and everything. Does anyone know what could cause this?
