The first thing I had to update was the original PSU. That's not too noisy, but I replaced it with a noiseless PSU. Big difference.
The second thing to do is to keep the internal fan running as low as possible. The goal should be to keep it at around 1000-1500 rpm or less for almost no sound. Don't go past 2000rpm because it gets too loud.
Did you voided your warranty by replacing your PSU and changing stuff like this?The second thing to do is to keep the internal fan running as low as possible. The goal should be to keep it at around 1000-1500 rpm or less for almost no sound. Don't go past 2000rpm because it gets too loud.
Few years ago I replaced fans on one of my old desktop computers and I installed manual fan control that is even better tham PWM fans.
Main problem I had with noise was coming from plastic mesh combined with incoming air, so I had to cut that off one part of a plastic with a knife
