darksparten Posted February 16, 2013 Share Posted February 16, 2013 http://www.youtube.com/watch?v=Roo4wg0FXzQ ^Noise^ Basically when the temps get high enough the fan tries to spin, it makes that noise for a few seconds, and then starts spinning normally. It's annoying because i alt-tab a lot and it happens everytime i get back in game. Still it's way better than my old crackly CX750 and I thank you for that. Any help?

LiptonICEI Posted February 17, 2013 Share Posted February 17, 2013 If. This is my video. Corsair did not yet responded with accuracy, but I think it is normal for the fan and then try to turn that noise. After touring all goes well, but not because difficult to start. :/ Link to comment Share on other sites More sharing options...
darksparten Posted February 17, 2013 Author Share Posted February 17, 2013 It's totally silent when idling, like browsing, with the occasional chirp or grinding(very uncommon). However when i start a game it'll make the grinding noise and then proceed to make beeping noises, it stops after a while, but after i alt-tab and go back into the game, it starts again.

darksparten Posted February 17, 2013 Author Share Posted February 17, 2013 And why is it that tech support for power supplies won't let you contact them with an issue and skips right to RMA. Link to comment Share on other sites More sharing options...
peanutz94 Posted February 17, 2013 Share Posted February 17, 2013 No,thats not normal for your PSU. It should be totally quiet except for normal fan noise. So it sounds as if the fan controller has some sort of issue or the fan. I would have it replaced. Link to comment Share on other sites More sharing options...
MacNB Posted February 17, 2013 Share Posted February 17, 2013 http://www.youtube.com/watch?v=Roo4wg0FXzQ ^Noise^ Basically when the temps get high enough the fan tries to spin, it makes that noise for a few seconds, and then starts spinning normally. It's annoying because i alt-tab a lot and it happens everytime i get back in game. Still it's way better than my old crackly CX750 and I thank you for that. Any help? I have exactly the same issue. RAMGUY asked me to return it as he wants to test it. ARMA raised. Nickjf20 had the same issue too. During low workloads/idle/browsing, the PSU is super as the fan is off...in "fanless mode". Even when the fan eventually turns on, it's still pretty quiet. It's the in-between state when it is hesitating to turn on that the buzzing/grinding noise is heard. I have had mine for less than three months and it seems to be getting worse. Also, does your PSU fan do power-on spin test ? That is, when you first do a cold power up, does it spin up ?

darksparten Posted February 18, 2013 Author Share Posted February 18, 2013 actually sometimes the noise happens even when the fan isn't trying to spin. Link to comment Share on other sites More sharing options...

LiptonICEI Posted February 19, 2013 Share Posted February 19, 2013 That video is from my PSU and is normal. Once the fan begins to rotate should not be noise (at least rotate at high RPM). It would be a problem if the fan NEVER rotate, but in my case it works correctly. Here the only strange thing is that it costs the fan start, but it only takes a few seconds (in those seconds makes the noise that we know all). Note: Every 20 minutes the fan turns on for a few seconds at high RPM and then off (even basic tasks and do not require the computer). This is normal I guess. Again, my source should work fine, because the fan rotates and in doing so no strange sounds. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 20, 2013 Corsair Employee Share Posted February 20, 2013 I have posted this many times and yes even on your thread LiptonICEI in fact it is from your thread LiptonICEI or did you have another issue? Yes the fan will not come on till the CPU reaches about 49 Deg C internally which will happen at about 40% + Loan on the PSU, and the Voltages look spot on so you should be good to go.

darksparten Posted February 20, 2013 Author Share Posted February 20, 2013 Well it's getting worse now. It'll make that noise even when the fan isn't trying to spin on top of a weird buzzing. This noise(both fan and buzzing) goes away momentarily when doing something, like when webpages load/posting replies but it comes back right after it finishes. also the noise goes away under usage(the fan starts to spin).
