Hello, I recently upgraded my PC's CPU, GPU, and PSU. Everything is working normally except for a brief loud buzzing noise that repeats a few times. It stops completely when I touch the CPU cooler radiator area with my hand or finger. I suspect something might be blocking a fan, but after replacing the fans, the sound continues. I’m not sure what’s causing it and would really appreciate any advice from someone who knows.

Hello. Usually, a buzz sounds like a rattling noise or a spark across a gap. Verify that all your power supply cables are firmly connected at each end. Sometimes it’s just a matter of snapping a few screws onto the fans.

If you can quiet the noise by touching the chassis, it likely means a fan or something inside the chassis is vibrating due to the fan. Once disassembled, putting it back together doesn’t usually solve the issue. I’d doubt it’s a simple fix. If this setup uses two fans, try unplugging the radiator fan while it’s running and see if it stops right away. A bad fan bearing could be the problem.

The simple way to dampen vibrations is by applying tape, rubber, or foam. Avoid using this method with fans for clear reasons.

I've spent time working with fans and done similar tasks, but we need to figure out what's causing the issue first.

Fan mounts can be secured with tape, just ensure they're positioned away from the fan blades to avoid increasing noise, vibration, or damaging the motor.

Typical PC fans don’t generate sufficient power to overheat. You might stop them completely, but high-end models that spin rapidly won’t reach temperatures that cause failure. Insufficient current flows through the wires. They usually handle only 250–500mA to stay silent.
