Hey all,

The fan in my power supply is noisy as hell. I'd like to try and replace it with a new fan. The power supply itself seems to work fine, its a 300w atx unit from pc power and cooling. It seems to have a standard 80mm fan in there. But i'm not sure how i could go about replacing it. There appear to be 2 wires directly connected to the power supply that connects to the fan.

Anyone know where i can pick up a QUIET fan to replace it with? would i just cut and splice the wires? or can they be removed from the actual motor? i'd rather not spend $80 on a new PS just to get a quiet fan.

thanks for any help.

Can solder the wires off the board, or you can cut the wires close to the old fan ...to leave some extra play... and then solder and seal the wires of the new one to that. I like using male/female plugs with fans because it's a lot more simpler to change them next time.

The fan is an average 80mm fan so you can shop around for a silent one, or can make it look freaky with one of those LED fans.

any problem with just twisting the wires together? I dont even own a soldering iron. Pc power and cooling sells an 80mm fan thats supposed to be quiet that i was going to order and use. It has a connector on it to connect it to the power supply, like you would connect a HD. I'm guessing i can just clip off that connector?

i dont really care about anything fancy, i just want some quiet :)

thanks,

Ian

Twisting the wires together should work if you make sure they can't get loose easily. And yes it is better to remove that connector and connect the fan directly with the wires inside the PSU.

My PC eats so much money that I'm in 'desperate' need of it to buy PC3500 RAM, help Svol with his OC project!

Don't just twist the wires together because twists often work loose, and since they have to be covered with insulation anyway you may as well use small wire nuts.

if the wire is long enough, you can just run in outside the power supply and plug it in normaly if your not comfortable splicing the wires. before you take the psu appart, unplug it (obvious but it needs to be said!) and let it sit unplugged over night. this will let the caps discharge.

yeah you can twist them all you want :) just make sure you tape it up before it touch something and short out. or use that shrinking thing people like
