Loud Power Supply

XFX Pro 650w, it runs really loud when I play games, which is understandable, but if I turn a game off and idle the PC it still runs at full speeds. If I understand correctly once the system isn't under load it should quiet down. I have used an air compressor to clean it out, cleaned my case filter, aired it out again with a can of duster, and I even propped my case up an extra inch to ensure airflow through my bottom vent. This is getting obnoxious to me because it is the loudest component in my system. The bearings don't sound bad at all, but more like a jet engine I guess. I don't think motherboards control PSU fans, so if it is running so loud all of the time it must be faulty? I've had it two years now and never really noticed my PC being loud until a few months back but I brushed it off as being my case fans. The air blowing out of the back feels cool too if that makes a difference. All I could guess now is my R9 270 is too hot, but I don't see it being an issue when it's idling, so maybe anybody knows what's up with the Pro 650's or a better solution than I've tried.

Edit: When I say air it out I mean mainly my PSU but I've blown out my GPU, the heatsink fan, and all the other crevices.

  1. Does your power supply have a hybrid feature? Both of my xfx power supplies does but I have more powerful versions and I believe better versions of what you have.
    How is the power supply oriented? With my system when I was overvolting my gpu and overclocking my cpu, I put alot of load on my power supply. When I had the fan facing down where I got air from the bottom outside of the case, It got super loud trying to keep itself cool. But after I flipped it so that the fan was facing up into the case, It got quiet.
    I flipped it so the fan was facing the inside of the case so that when the fan was off, the heat would rise out of the psu and get taken out of the case by the case fans and when the fan was on, the heat still rose out making it run cooler.
    Im also water cooled so it didnt make my components run hotter

    So try flipping the power supply around in your case

    I don't think it has hybrid feature. I flipped it around and it runs the same speeds. I guess it's just a loud psu although I've never heard ones this loud even on old models. Also I blow it out as much as I can but I cant get dust that accumulates on the undersides of the fan blades, the only way to get to that with a qtip or something would be to void the warranty and remove the metal grate. I'm not sure how many years I get warranty for the power supply, I believe it has been just over 2 years now maybe coming up on 3.

    XFX Pro series power supplies come with a 5 year warranty. I'd recommend RMAing the power supply since you are covered via warranty.
