Corsair 750TX fan not working?

I put in a new Corsair 750TX into my new build a month ago, and I randomly checked the back near the PSU, and I can't feel any air blowing out; does this mean the fan is not working? I noticed there wasn't a PSU - Motherboard fan connection, that is by design I assume, or was mine missing something (I did some research and it seems like this is standard). My computer hasn't been on too long and it's not working too hard so it's not hot back there or anything, but I don't feel any air blowing out - should I? I also took a flashlight and can't see a fan moving (nor could I see one when it was off).

Am I being paranoid, or is my PSU defective?

  1. I am an owner of the same power supply. If you have an efficient system and nice cool room, your fan does not need to be spun because all the capacitors are within your temp limits.

    The fans in the Corsair power supplies are temperature controlled. The psu fan will not increase to full speed until the temperature rises sufficiently.

    A few years ago there were a lot of complaints from users who did not do their homework and did not know about the temperature controlled psu fan.
  3. Ok, thanks for the quick response!
  4. I keep plastic tie handy to check fan rotation .... insert very slowly on fan end till start to hear a noise....simple but effective :) .... wont stop fan unless ya jam it all the way in....but as always care should be exercised not to damage anything and you shouldn't try unless you examined the construction b4 assembly.
