Coil whine
Coil whine
Hello, your 7900xt (refurbished by microcenter) seems to be experiencing significant coil whine, similar to what you had with your Arc A770. This might be related to the PSU you're using. Your current setup uses a Montech 750W Century G5 Gold, which is about six months old.
Your power supply unit should work just fine, but you can try another one to compare performance. Coil whine can stem from many reasons and is tough to fix. The best solution is to increase fan speed to full power or play loud music so it becomes inaudible. That’s simply masking the problem rather than solving it. Another step is to investigate where the coil whine originates. Open your PC and run a game known to produce this noise. Be very careful when handling metal parts—avoid static shocks. Gently touch different areas like the GPU cooler, backplate, or fan hubs (not the blades). Stay away from exposed electronics. If touching any part changes the sound level or pitch, it likely points to a loose component that can usually be fixed by tightening screws or adding a thermal pad. Coil whine tends to decrease over time, so it might become less bothersome. Finally, consider Micro Center’s customer service—do they accept coil whine as a valid reason for returns or exchanges on refurbished GPUs? Good luck.
Thank you for the details. I'll return to Micro Center to check about the exchange.
