• PSU's fan makes alot of noise
    13 replies, posted
Today, I came home , stArted my pc but it made a lot of noise. I opened the psu and removed dust. I opened the casing of the psu to clean it and I did't touch anything except the fans. I put everything back and it still makes a. Zzzzzz noise. Not a rattle sound, more like a huge bee. Anything? Specs mobo fsb1066 conroe graphics card hd4650 2 gigs of ram 1tb hdd intel core 2 duo 2.4ghx how much watt should a new psu atleast be in order to run my pc? Sorry for the silly typos, I'm typing this on my iPod touch and I'm not really used at it yet
Make sure the power lead is pushed all the way in. When they get loose, they buzz/crackle.
Either what Carl said or it's a broken capacitor? Also, if you really do want a new PSU, you can get 400 watts, that should be fine.

Anyways to re assure OP, 400 watts is enough because the 4650 draws power from the motherboard. Make sure you buy one that is at least 80% efficient so you don't get ripped off by buying a garbage psu. It'll say it on the box somewhere.
Thanks for the answers. I was kind of scared that something'd go wrong if I would try to boot the pc. Well, I just did and somehow, the noise stops somewhere just before you see the desktop. It's really weird, I'm not really in for buying a new PSU (money) and I don't want to have this current one to break while I'm in the middle of my homework or something. I've looked this problem up a little on the internet and many people say that there's usually something wrong with the fan, and replacing a psu fan isn't the easiest and best thing to do. The power lead is pushed in correctly, so nothing wrong with that. Also, if I'd been looking for a new psu, would it matter alot which one? I mean, do you closely have to look at the specifications of the psu to see whether it's compitable with your motherboard? So would something like [url=http://www.newegg.com/Product/Product.aspx?Item=N82E16817171046]this[/url] do? Also does it matter if the watt of the psu is a lot higher than needed? And last, I somehow cannot see how much watt my current psu has. It does not list anything about watt on the label and searching the model on the internet brings up many strange things. I took a picture of the label, the the small numbers and letters are vague, but I don't think that matters that much. [IMG]http://i46.tinypic.com/23ma7uv.jpg[/IMG]
PS-400A suggests 400W
Just because you cleaned the fan that doesn't mean it's not the fan Try physically stopping the fan for a second when it's running (also you probably shouldn't do that too often). If the sound stops, then I just saved you [Cost of a new power supply minus cost of a standard 80mm fan] Also I've got a feeling your psu is more 300W than 400W, despite the name

But how are you supposed to replace a psu fan? I've opened the psu and saw two wires from the fan to somewhere in the psu, but not like a little plug or something, it was soldered. Not really something I'd like to do. If it continues, I'll just buy a new psu (unless replacing a fan is actually a whole lot easier, safer and cheaper than I think it is). I don't want something to happen to the computer while I'm in the middle of something important.
1) Buy a new fan 2) Unscrew old fan 3) Cut fan wire by the end so you get the piece as long as possible 4) Cut fan wire on the new one or make a female fan plug for the psu (which will take some time) 5) Connect red with red and black with black then use a tingun to make them securely connected 5b) If you have no experience with the tin gun or whatever, expose at least an inch of wire on each side and twist them well 6) Secure wires with electrical tape (I wouldn't really use normal tape) 7) Reassamble Just check the fan voltage and other things first. It's very, VERY unlikely to have a different voltage/whatever. If it's made for molex or has the 2/3/4 pin mobo fan connector it's fine. Also if there's a third wire, you can ignore it. That's the rpm counter. It's not needed for fan operation.
Cutting wires a power supply and then taping them is only going to end in tears and/or a fire. Don't be a cheap skate, just save up and buy a new power supply.
I have a few suggestions. 1) When working on a power supply unplug it then try to turn on the computer to empty the capacitors, this will ensure you wont be killed. 2) More wattage then you need is a good thing as having some headroom with electrical devices is always a good idea.

Unless you're absolutely completely incompetent and can't see loose wire and are unable to operate electrical tape, then yes. Otherwise it's just silly.

I never touched anything inside the psu with my hands btw. I just took a look on whether there was something wrong that I could see and removed some dust (there was quite a lot dust in it) I notice that when I run it, the noise begins (quite bad, my parents could hear the sound this morning when I turned it on), but after a few minutes, the sound gets lower and lower and finally it doesn't make any sound. The fan is still active though. Does anybody have any suggestion to fix this annoying sound? Without buying a whole new psu or replacing the fan. I made a screenshot of speedfan where it shows some voltages. I don't understand much of it but maybe someone does recognizes something strange?
