What's this sound?
My computer began producing this noise recently. It only occurs when the room temperature drops and after waking up from sleep. I suspect the power cord or the PSU might be involved, though I'm not certain. Once it stops, it doesn't return while using the PC and operates normally. 20220410_235727.mp3
1: fan blade striking an object
2: CPU air pump appears clogged, likely making a similar noise.
Inspect every fan for any contact with wires or components. It seems too rapid to be an AIO pump, though I might be mistaken. The quick shutdown after startup suggests something may be dislodged during operation, possibly related to a fan problem, which could explain the noise only at startup.
A single noise resembled a grinding bearing, though it was unclear. The video clearly shows significant damage. Despite this, it handled high temperatures well. It might indicate an issue that hasn't occurred yet. If no overheating is present, the problem could involve a wire striking a fan component.
