One of the fins of the PSU is broken. It's causing an annoying and loud vibration noise. It's been like that for months now, and there's been no other issue. But I've been thinking of breaking the opposite fin to stabilize the fan. It's a simple, cheap PSU, and it powers a weak computer with a 7th gen cpu and no gpu. Surely the difference in airflow would not create a fire hazard... Right?
