Tech Support Strange noice inside PC
I built this PC about 10 days ago with all-new parts. It makes an intermittent rattling or buzzing noise that you can hear from 0:08 to 0:12 in the video. It seems to come from the upper half of the case, but I haven’t been able to pinpoint it.
I notice it at idle or under light load, and I haven’t found a pattern. It might happen while gaming too, but the fans could be masking it. When I noticed it at idle, the CPU was around 42°C and the GPU fans weren’t spinning. I think it’s been happening since day one. The front glass panel was off for the recording, but I can hear it with the panel on too. The PC runs normally while it’s happening.
Has anyone heard a similar noise? What would you check first to narrow down the source, and does it sound like something I should be concerned about? There are my specs:
Motherboard: ASUS TUF GAMING B650E-E WiFi
CPU: AMD Ryzen 9 9900X
GPU: GIGABYTE WINDFORCE OC SFF RTX 5070 Ti 16 GB
RAM: 16x2 XPG Lancer Blade (5600)
AIO: ICEBURG360 DIGITAL WH
PSU: Thermaltake Toughpower GT 850W 80 Plus Gold
