noisy psu fan

[adalgisa]

The fan of the FSP psu that I put in a couple of years ago has gotten noisy. The sensor shows CPU, mobo, HD temps are ok; and the psu fan is still running. Do I need to do something about it?

Maybe give the PSU a few shots of compressed air to clear out any dust that may be causing the fan to labor. Otherwise, keep a close eye on it. It's not really feasible to replace fans in PSUs...

I would suggest dusting it out a bit, it can only help. A PSU can be rather harmful to the rest of a computer if it fails so getting a quality product and keeping it maintained important.

I have replaced fans in PSUs before, you just have to be careful and know what you are doing. First of all, before opening a PSU you need to unplug it and let it sit for at least a day for all the capacitors to lose their charge. Opening you PSU will void any warranty on the product. In my experience the wires powering the fan will be soldered in, not connected with a 3 or 4 pin connector etc. So you will have to have a fan that fits, soldering iron, solder wick, solder, and a screwdriver to do it.

Let me rephrase... It's really not feasible for the average user to replace fans in PSUs. And be careful... those capacitors can hold enough charge (even several days later) to shock the beetlejuice outta ya.

Yes you need to very careful if you decide to do this, be very careful not to touch the capacitors. Just wanted to let you know this option was available to you.

If you do decide to replace the fan instead of the whole PSU, let the PSU sit unplugged from the wall outlet for at least 24 hours to let the residual electricity trickle out of the capacitors. The longer you let the PSU sit the better.

I've replaced many PSU fans and I always let the PSU sit for a few days before I open it up. Then I only touch the fan if possible.

Compressed air sounds like a better option than potential electro-shock treatment! If that doesn't make a difference, I'll replace the whole psu. --Thanks for the advice.

I think the noise from the PSU is because of the dust or lack of lube. So I advise to oil the PSU fan, I have ever used peanut oil. But I think the final solution is to change a PSU with 12cm or 14cm fan, that can be much quieter.
