    fans normally spin, but I took the computer apart to fix a raid issue and my friend noticed that my psu fans weren't spinning. The casing isn't getting hot and I put a fan up to blow through it and the air that came out wasn't very warm either. Are the fans dead or do the power supply fans only come on when it gets hot? I never really paid any attention before.

    Power supply is an Ultra X-Finity I believe. I'm not at home so I'm not for sure.

    Thanks

    Nevermind, I'm a dumbass. It is thermally controlled and it apparently just isn't getting hot enough to spin the fans. I just fail at reading tonight.

    Well it's good that it's running normally.

    I was going to say how my psu has a fan off setting for moderate use when I want it quiet.

    It's a big 140mm fan, so it's quiet anyway. But it's a nice feature nonetheless.

    Yea it's definitely nice. I have a 120mm mounted to the top of the case directly behind it and apparently it pulls enough air through the PSU to keep it from having to spin the fans on its own until I start gaming pretty hard.

    It is a Centurion 5 that I cut a 120mm top vent into but I'm getting a Stacker 810 this weekend and I'm planning on putting a couple 120's in the top of that

    What are you running that you need so much airflow?

    You overclocking or something?

    I have about 10 harddrives and an 8800gts 640 that I like to keep as cool as possible.

    I may start overclocking soon, I just haven't gotten to that point yet. Mainly I wanted the extra space that the stacker offered. But I love keeping things cool and sound doesn't bother me much.

    make sure that's normal.
    some thermal controlled PSU fans are limited to 'reduced' or 'increased' fan speed, not 'stop'.

    Yea, I'm going to test it sometime this week by closing up the case and playing Crysis for a bit to see if I can get it to kick on. If I can't at that point I'll be more concerned.
