CX430M noise

[Ali777]

Hello,

 

I have a CX430m power supply and it makes a horrible noise

it is like this video

 

 

I noticed that when I put the PC on its side the sound goes away !

What do you think is wrong here ?

[Matty2hatty]

It's coil whine.

[sushisharkjl]

Normal.

Maybe get a better PSU though?

[Ali777]

The sound is too loud to be normal , and I don't think coil whine sound like this

I have tried VX550 and VX650 before, they were not this bad

 

what is weird that the sound disappear when I put the PC on its side

That's not even close to coil whine... that sounds more like a bad fan

If it goes away after you put your PC on it's side only thing I can think of is bad bearing.

It's a fan.

Try pushing it inwards with something like a pencil with a rubber or something. Use some force until it pops further in. That's what corsair said when I had a problem like you.

If that doesn't help, try lubricating it or replace it yourself, RMA it or buy a new PSU.

I will try it and see if it works

I ended up replacing the fan with Noctua NF-F12 PWM. Now its super quiet, the only noise from my PC is the Hyper 212 Evo fan which I may replace it soon with Noctua NF-F12.

 

Thanks to @MG2R for his video https://linustechtips.com/main/topic/6392-knex-server/

 

I connected the fan directly to the PSU and monitor it throw the motherboard
