Any Way to Test PSU Fan? (feat. Corsair CX650M)

[NarimaanV]

Hi,

       So weird topic I know, but is there any way to test the fan of a non-software controlled PSU like a Corsair CX650M? By test I mean ideally make the fan run at high RPM for a minute or two? The other day I thought I heard my PSU making this weird sound like a mis-aligned or dodgy fan. There's 2 days left before MicroCenter will exchange it for me (would rather not disassemble the whole thing if it's fine...) and I'm trying to see if there's anyway to confirm the fan has an issue or if something else in the case was just making an odd sound. I've tried stress testing with Realbench but since it's a 650W power supply and I'm running a 7700K (not overclocked yet) and a GTX 1080, I don't think it's putting a whole lotta stress on the PSU to make the fan need to run much . Any thoughts or idea would be greatly appreciated (or even being called crazy and that something else was obviously making the sound and my PSU is fine) .

 

P.S. I already checked the chassis, CPU cooler, and GPU fans (stopped each with my finger for a second when I heard the sound, nothing made it stop).

you could bridge the PSU pins to turn it on, iirc that starts the fan

Cxm series? Yeah you got a bad fan. I filed an rma through corsair for mine, the reps were nice enough too. When they told me to mail it to them and didn't give me a prepaid label I wrote back I'm in college and don't have money for that. After that they got a prepaid label. Total turn around time was about 3 weeks but I just bought a 650w supernova instead. 

 

Corsair support is excellent, and you have like a 5 year warranty.

So that did get the fan to spin, not sure if it was full speed but it was running. Left it for a little bit like that and didn't make a sound again. Tried stress testing for an hour again and still no sound. So as of now I guess it was just something else?

Well that's good to hear that their customer service is good. For now it seems to be fine so I probably won't return it to MicroCenter. And yeah I've heard good things about the Supernova series. Will probably be the next PSU I install if I upgrade in the future .
