I have severe tinnitus, and the combined drone from my PC's fans can aggravate it. My GPU is an MSI Ventus 3X RTX 5070 Ti that has been undervolted to around 200–220 W, but its fans still produce an unpleasant noise at roughly 1200 RPM. My Noctua CPU and case fans are quieter and usually stay between 200 and 800 RPM, although their combined sound can still become uncomfortable.
The current case is an old, heavily modified Lian Li PC-70B with loose parts that vibrate. I'm replacing the power supply soon, so I plan to add foam, rubber or silicone damping, grommets, and gaskets while everything is disassembled. If that doesn't help, I'm considering a Fractal Torrent with large 180 mm fans, or a Corsair 4000D with two Noctua 200 mm fans. The computer sits well above the floor on a ventilated shelf and would also be raised on foam pads.
For anyone sensitive to PC noise or living with tinnitus, what has actually helped? Would reducing vibration and using larger, slower fans be worthwhile, or would changing the GPU and moving the computer farther away make a bigger difference?

Be careful with heavily sound-dampened cases. They can make modern components run hotter, which causes the fans to spin faster and can end up louder overall. I’d prioritize airflow, vibration isolation, and fixing or replacing the noisy GPU rather than stuffing the case with foam. Rubber fan mounts, silicone screws, and pads under the case can reduce rattling without obstructing airflow.
Active noise-cancelling headphones or earbuds are probably the simplest solution for steady fan noise. They can make a surprisingly big difference without having to rebuild the whole computer, especially if the noise is more of a broad low drone than one pure tone.
That approach has worked well for me too. Good ANC headphones make the background fan noise almost disappear, and they avoid the trial-and-error involved in finding fans that happen not to trigger a particular frequency.
Distance is underrated. If possible, put the computer below or farther away from your listening position, keep it slightly raised for airflow, and use longer display and USB cables. Even a modest increase in distance can reduce the perceived noise more effectively than adding panels or foam. Also consider using a quiet secondary computer for non-gaming tasks if that fits your setup.
If the GPU fan is the main offender, changing to a model with better cooler acoustics may accomplish more than replacing the entire case. You could also adjust the fan curve to avoid a resonant RPM range, provided temperatures remain safe.
