What leads to the static-like grinding sound coming from your PC?
When engaging in certain games and staying on after closing them, I experience a mild static-like grinding sound from my PC. I wondered if this was related to the fans, but I turned them off with the fan control for a moment to check if it would stop, and it didn’t.
The specifications of the PC are typically minimal, with no excessive moving components like fans or rubbing parts.
CPU: Intel Core i5-12600KF 3.7 GHz 10-Core Processor

Power Supply: be quiet! Straight Power 12 750 W 80+ Platinum Certified Fully Modular ATX Power Supply
I recommend checking the side of the case to pinpoint the source of the sound.
I believe the AIO is located in the roof.
I notice a noise from the AIO intake fans when they spin above 1200rpm (my model is a 360mm Arctic Freezer II), so I usually set the fan speed to 900 until the CPU temperatures exceed 60°C.
Here’s the link to the specification sheet: https://www.arctic.de/media/be/9e/c5/169...update.pdf
The pump reaches full speed at 40 PWM, which is the minimum I use.
If you allow BIOS to manage the fans, they run around 1300rpm even when idle... my CPU doesn’t require that much speed usually.
