One of the 3 fans in my computer is really loud.I'm thinking of replacing them but i need to isolate the fan that is loud and also i don't know what specifications i need to meet for it to work could someone help?
Well if its not attached to the motherboard in any place, for example the heat sync, or the cpu, then you can remove the fan, any other place, you shouldnt replace it because the mother board sets the fan at a certain rpm, and which would sound loud with any fan. I know this because i replaced the fan on my sony computer, and on a generic motherboard, and it was quiet, but when i put it on my sony computer, it was loud, so if you want to replace your fan, i suggest liquid cooling, it is completely quiet, and keeps your cpu much cooler than a fan. Best of luck.
Open up the case (of course). If you can reach the fans with your finger or a soft washcloth, you can touch them in the MIDDLE, not along the blades, and see which ones make noise and which do not.

What needs to happen is you need to take all of the screws off of the back. Then there should be 4 screws on the bottom of the base but you need to take off the covers to them first before you can remove the screws.
Once all of these screws are taken out, you'll need to sepearate the back cover from the front, there will be latches that you need to move with a flathead screwdriver and you'll need to do this a few at a time so you can start removing the back cover easier.
You'll eventually remove the back cover to expose the insides of the computer. Now go ahead and plug in the Sony AC Adapter and turn on the computer and from that point once the fan gets loud you'll know which one you'll have to replace.
