    Making a PSU Completely silent

    I have a 250W PSU. Good quality and temperature controlled.

    However, I want to make it completely silent.

    I really don't want any fans in it at all.

    Any ideas?

    Rather than no fans at all, get some silent fans in there and undervolt them. It will be as good as silent and will keep a bit of airflow going.

    I'm not a fan of changing fans in PSUs. The ratings they give out on PSUs are often tied closely to temperature, and they aren't going to use fans that give them all that much headroom. Putting a quieter and lower CFM fan in isn't something I recommend (not that I haven't done it without success.)
    PHP Code:
    $s = new signature();
    $s->sarcasm()->intellect()->font('Courier New')->display();

    Modified psus are a good way to void your house insurance in the event of a fire....

    To be honest, I think modifying a piece of equipment that can be potentially very dangerous is not a good idea. Especially if you're trying to reduce the cooling. Either stick with the PSU or save up and buy a silent passively cooled model.

    On a slight detour, I've just ordered a 60mm SilenX fan to shove on the back of my Shuttle PSU (200W Achme) with a fan adaptor - hopefully it'll make it somewhat quieter .

    Tons of people use their existing fan but move a wire from it and solder it onto the circuit board somewhere else to give 5V. Should be fine if its a low heat system. Many of them even have all the heat from their systems being blown out through the PSU

    Should be fine
