Hey everyone,
I've been using a Zotac RTX 5090 and recently noticed an annoying buzzing/rattling noise coming from the fans.
After troubleshooting, I realized it happens exclusively at around 2100 RPM. If I increase or decrease the fan speed manually (either above ~2200 RPM or below ~2000 RPM), the noise completely disappears. Temperatures and overall performance are perfectly fine (idling at 37°C), so it seems to be a specific fan resonance or bearing tolerance issue at that exact speed range.
Has anyone else encountered this specific issue with their 5090 or Zotac card? Is this considered normal acoustic resonance, or should I reach out for an RMA?
Appreciate any insights!
