The first time I bought my pc, it doesn't make so much noise until recently I feel that the noise from the computer bothers my sleep if I don't turn off at night. I found out that the noise comes from my power supply, but I'm not sure whether the fan or other parts inside the PS box that's making the noise.

So I'm just wondering how I can fix it. Should I pull out the PS and check if the noise is from the fan or I can just leave the PS there and fix the fan or something?

Thanks. http://www.PCGuide.com/ubb/smile.gif

Is the computer still under warranty?

If it is get the company that sold you the computer to replace the power supply, if not then a new power supply is in order, the expense of replacing the fan is problably more than that of replacing the whole power supply.

I agree with mjc, The risk of opening up a PS is far greater than the cost of replacing it. If you are not having any problems i.e loss of data, lockups ect I would try blasting the fan with compressed air to dislodge any large dust balls or paper debris.

Good luck

Hello BoBo,

In case you still want to proceed with an attempted repair........
If the rest of your power supply is fine and you dont have the money for a new PS
Get a $7 regular computer case fan (the kind that has the little white plug on it just like the one that goes into your hard drive) Standard fan or get a high speed fan if you can find one...........(No soldering required with this repair, and less chance of creating yourself a problem)

1. Completely unplug your computer
2. Completely remove the Power Supply
3. Remove the screws in your power supply case and remove the cover (Take Your Time, and disturb as little as you can manage)
4. Remove the 4 fan screws, and cut the wires to the existing power supply fan, and remove the existing fan
5. Tape the bare wires ("Make Sure" they are "Not" going to touch "Anything" after you reassemble it)
6. Clean out the dust (use air "keep your hands outa there" as much as you posibly can)
7. Install the new fan, and route the power supply wires for the fan out the hole with the rest of the wires, and connect it back to one of the power connectors coming out of the power supply.....(hope that made sense)
8. Reassemble the case and install back in your comp

If you smell a "Very Mild Burning Smell" right after you turn it on, most likely its only a little bit of dust you disturbed while you were inside, and didnt completely get cleaned out.....But be careful and monitor it for proper operation or any sign of problems for at least a day or two after you do this (That is if you choose to do it)


This is not a recommendation, Only an explaination of "one posible way" of making a cheap repair..............

Good Luck! and be careful if you choose to proceed "Be Very Careful!"

Edit:
I strongly agree with some of the above statements.....before you preceed, make sure you cant get a waranty repair, and by all means if you can afford the new power supply, get one and forget about doing this.......

I have however been successful in doing this myself a few times, so it is entirely posible to do if you choose to try..........

You should investigate the source of the noise more thoroughly
before you do anything else.

Air currents inside the case can carry the sound caused by a
failing CPU cooling fan out through the PS exhaust.

Remove the case cover or side and then power up to check for sure.

Yes, I've opened the case and listened to the noise. I don't think my PS is still under warranty. So I'll probably get myself a new PS then.

Anyway, thanks to you all for your suggestions and time. http://www.PCGuide.com/ubb/smile.gif
