TX750M fan twitching, noise, on idle

Hi

 

My psu is brand new, and I noticed that when the pc was in idle, like just browsing websites or nothing at all. I noticed that the fan tried to start spinning and when that happens a annoying noise is made.

 

I verified that the fan works by running furmark or heavy games. It's just when it's idle.

 

I recorded a video where you can see this happening. Notice the noise when it tries to spin up. It may not sound much but it sounds in whole apartment.

Should I return it?

Yes, you should RMA. I had a very similar problem with my TX750M, and others have reported the same. I bet you'll find you PSU has to get quite warm before the fan runs properly and cools it down. So instead of a constant temp and a gradually increasing, quiet fan, you get a build up of heat, and then a fast fan for a few minutes before the cycle repeats itself.

 

Whenever you see a fan rocking back and forth or start-stopping like that, either the fan or the controller is faulty, because it's not getting enough power to run properly.

Thanks a lot for the help.

Hello

I just got the same power supply on an RMA and it is doing the exact same thing. I am concerned that when I RMA it, I will get another one with the same problem. Is this a common problem with this psu or are these isolated incidents? Has anyone got a this psu without this kind of issue?

Explain that the problem is still occurring and request a different model psu.

It seems like most units from that series have this problem.

Alternatively you could always just sell that unit and buy something else, that's what I did.

Just an update. I went to my retailer and they couldn't reproduce the problem because they can't get the exact environment as I have at home.

 

I showed them the video and agreed that it shouldn't be doing that. But they still didn't let me RMA it.

 

Can we get a Corsair person answer? Should I RMA to you directly? Is this video enough proof?

 

Is there maybe a way to force it to be always on? Because the fan doesn't make any noise when it's spinning, so I rather have it do it all the time instead of making this very irritating noise.
