Do I have coil whine?

[Lalorm]

Hi All,

 

So I just finished building a new PC and It's really quiet.  I've used all Nocuta fans and it's REALLY quiet... except when the PSU fan turns on.   It'll turn on for about a minute and while on there's a loud whiring sound.  I thought it could be the fan, but when the noise stops the fan is still moving and slowing down to a stop and it doesn't make a sound so it's not the bearings etc.  So is that coil whine in the PSU or something else?  I thought coil whine is constant but I could be wrong.  I have coil whine on an amplifier and this sounds different to that.  Is there something I can do about it to reduce it?  It's really annoying.

 

The PSU is a new Corsair RM1000e  

 

Regards

Not really. The noise can change or just stop. It's linked to the load changing on the CPU and/or GPU. Or your whole system, if it's your PSU. 
The intensity of a scene in a game for example can influence how the coil whine sound.

i mean... dont you think a video or audio recording would help? we're just left guessing here otherwise. 

 

*if* its the your psu, you maybe could have the fans running constantly (if it has that feature) as it might alleviate this noise... not ideal, but other than that there's nothing you can do about it, *if its the psu, be it coilwhine ,or something else".
