Hello, I built my PC about +-1 or 2 years ago and I decided to maintain the same PSU from my previous build, the Corsair 650TX (the v2). About 4 to 5 months ago I started to notice this unusual fan noise during start up and it would just reduce/stop once the machine is already going (i.e. Desktop loaded, start up programs). First I though it could be dust accumulation or cables touching some fans, I've used compressed air in the whole case and replaced some fans, same noise.
So should I worry about this noise and look for a new PSU? or It's something normal that would not cause a sudden problem in the system?
Thanks for reading...
