PSU Fan dying?

post #1 of 11
Thread Starter 
Tonight I hear a noise coming out from my comp, so I went to check. I saw the PSU fan keep spin and stop, spin and stop. My PSU has a 120mm fan blowing out on top. I thought there may be some dust trap inside, so use air duster to blow it. It doesn't work, so I took off the fan grill and use air duster blow some more and I put back the grill. Now the fan work, but sometime it has little noise. But the noise is not as loud as before.

I wanna know if is the fan dying or it has some dust trapped inside? I run my comp 24/7, so is it safe to keep it run 24/7 now. I worry thefan died when I'm not around. I'm using the 900 case and the side fan is blowing to the PSU.Wll this help cooling the PSU? What happen to the PSU if the fan died.

Thank you so much.

[Edit] What Happen if the PSU fan completely dead and I did not notice? Will it burn up and start fire?

yea you have dust...what i would do is if you have an air compressor....that and blow some 140psi air up in there...maybe less to be safe to blow that dust out of there cause thats mostly why fans die. (like my moms PSU...it burned up..smelled like burnt circuits.) then take a hair dryer to it like you would to shrink wrap so as not to get it too hot but to make sure no large amounts of moisture stays inside the fan housing

How long have you had the psu? Is it still within warranty? If the fan dies completely, your psu will most likely die a gruesome death if you don't notice the fan soon enough. If it is still within warranty I would start a convo with CM, tell them what you said here: the fan was stopping and starting and you cleaned it as well as you could, but that you are still nervous about the fan failing and see what they say.

I got it on last December, so I think I still cover by the warrenty. I already contact CM, now I'm waiting for reply. It is weird that last night it make a huge noise and the noise gone, so I went to sleep with the comp on. I check this morning and the fan move a little slower than usual, but the noise is gone.

BTW thanks for reply. +rep

The fan is supposed to spin faster or slower depending on temperatures inside the psu, so it could have just been cooler in your room this morning. Just keep an eye on it, the noise stopped which is a good sign.

It can dangerous if you do dumb stuff like poke a cap with a screwdriver . I tend not to recommend opening up the psu just for the fact you give up your warranty when you break the sticker.
