replacing fan

Recommended Posts

Do computers need specific fans to work (like with their voltage) or can you just get any fan that is the right size?

I have a Sony Vaio VGC-RC110 and i wanna replace it's fan with this http://www.frozencpu.com/fan-22.html

I'm an amateur so I don't want to order it only to find out I didn't know something beforehand so any help would be greatly appreciated.

so 125 mm is way too much? Is it common for people to use it? I think the noise level is important to me too; exactly how loud would a 125 mm fan be like? would it be as loud as a vacuum cleaner?

thaqt fan you picked out is 50db thats not quite as loud as a vacume cleaner but close, personaly i would go with the one disturbed posted.

Nope.. lol

Personally I like a quiet machine... mine's not real quiet and it irritates me sometimes.  Ideally I would like to have a whisper quiet machine, but short of putting it in another room, or an insulated, ventilated cabinet, it's pretty hard.

An example:"This Aspire Multi Fan Speed Controller helps keeping noise level down while maximum your cooling capability and give you the ability to take control of your case fans"

I am hoping this is a good explanation.

it is basically a voltage regulator that allows you to control the fan speed.

You can build you own..  I built one of my case about 4 or 5 years ago.. I will dig up the pics..  It was just a simple on/off switch but you would be amazed how much it helped..

One other thing..  If you already have a case fan in the computer make sure that you are not creating a vacume inside the case.. otherwise that will not help the cooling system.

so true, your system can actually get hotter if you let this happen.

if noise is a prblem add static proof paper inside make it think and the noise is muffled a bit

sometimes it makes it echo depending on the paper and position

or make a cabinet for it out of air vents i seen ppl do that and use air filters to keep it more quite and clean 2 make sure u use vents on both sides of the cabinet better if its made out of rubber or plastic vents so theres less static make it big so u can give about 3 inches away from the pc case to the air vents to prevent static discharge

From what I have seen.. the sounds dampining materials, the stuff you stick on the inside of your case, acts like insulation..  So if you have a heat problem or are running a little bit warm.. it is just going to be amplified by that stuff..

However,  I do think that the rubber gaskets work... I was rather impressed by the difference that it made on one of my cases.
