Loud power supply fan

So how the heck do I make my power supply fan quieter? If I touch the metal screen protecting the fan in the back, the noise stops for a second. And I'm NOT going to keep my finger on the power supply all the time.

 

It sounds like your metal screen is vibrating. See if you can tighten any screws on anything.

Also, you could check if your fan is even a variable speed fan. If so, it should have 4 wires to the motherboard instead of 3.

 

For some reason it's pretty quiet now. Maybe it's my magic touch of my finger.

It's not a variable speed fan either. I was thinking of maybe taking the power supply apart and seeing if I could balance the fan blades. I've got to replace my Dad's power supply on his computer, maybe I'll try it with that. I'm sure his PS has a fuse inside. They're usually soldered in.

 

I got a nice pair of tin snips and cut the fan screen out, makes whole machine run cooler, fans don't like blowing against a screen, it puts pressure against the back bearings on the rotor.......also some shops don't like hunting down a xp power supply, so they will say you don't need a new one, I actually got a shop nerd to admit this, YOUR BEST BET IS TO GET IT OUT OF THERE AND REPLACE WITH NEWEST YOU CAN FIND.
a over heated power supply can fry your whole system if it shorts out

 

My fan in my PS is running pretty good. I told you it was my magic touch of my finger. After I swapped out my Dad's PS, I took his old one apart. There weren't a fuse soldered in anywhere. So that's going in the trashed electronics box that's going to BestBuy. I remember a few years ago on a couple of power supplies they had fuses in them. I guess the manufacturers want you to buy a new PS instead of changing a fuse.

 

this is why the water is poison , throw out pollute and buy a new on.

 

There was a noise problem on my PC in the beginning. Either it came that way, or the computer shop did something when they were upgrading to 8GB RAM, replacing the CD-ROM with a DVD burner, or putting in the mobile-rack. Anyhow, my tech guy got into the PC, took out some screws, applied some silicone flexible sealant/glue somewhere, then more under the screw heads, put it back together, and no more vibrating. I'll never get into the PC myself, but I buy Gorilla Silicone Sealant, 2.8oz. Clear, and use it a lot. It dries into a flexible rubbery mass. Last used it on the table fan grating to stop them from chattering together.
