Hi, I recently swapped out my EVGA 650W for a 850W PSU. The 850 fan seems to be running loud and I am assuming at full speed on idle. Actually it's the loudest part within my new build, though I have 1 rear, 1 top and 4 push/pull fan config on the go.
 
It's not annoyingly loud but noticeable. My previous 650W ran quietly.
 
I know I have the eco mode option but I prefer regular airflow at lower RPMs. Is there anyway I can reduce the fan speed or set a curve? Or could this be a faulty PSU?

    The fan should not be audible even under load. Have you done the paper clip test or perhaps used the detection tool included with the unit to isolate the PSU from the rest of the system?

    Can you provide more details about the 2 tests. I haven't tried these.
     
    The detection tool you speak of, is this the black connector with no cables attached which came with the PSU? If yes, please provide the necessary steps to run this test.
     
    BTW, the fan noise, in last 4/5 days since installation, has become a little less audible though still louder than my case and rad fans which are set on 'silent mode'.

    Paper clip test: http://cdn.overclock.net/a/ad/500x1000px-LL-ad9e1227_atx-connector-20-24pin.jpeg 
    This will power the fan inside the unit. 
     
    Start by having the PSU plugged to a working wall socket, connect the paper clip or detection tool to the end of the 24-pin cable and then flip the switch to on and be sure "Eco Mode" is set to off
     
    The detection tool is basically the same thing it just makes it easier to troubleshoot the unit.

    Should I disconnect all other cables (VGA, SATA, PERIF, CPU, etc) before running this test?
