Replacing PSU fan?

mattylad · 29 Jun 2013 at 23:52

Hi, the fan in my PSU is extremely noisy (apart from that the PSU is perfectly fine) so I want to replace it with a quieter new one.

I know it's 120mm and from old ATX psu's I have repaired they were usually just 12v 2 wire ( no speed feedback etc) so can anyone reccomend a good silent (and cheap) replacement?

Will something like the artic F12 case fan be the same?

The job of changing it is no problem, I know about the safety side etc,

Cheers.
Matt

Oh, has anyone done anything with their PSU fans?
Like making them temperature controlled or even putting speed controllers on?

What PSU do you have and whats the spec of your system?

Hello, its an Atrix 500T.
May not be the best but it works and is not giving any problems.

The rest of the system is a Phenom 2, M4A785TD-V EVO, 8800GT, 1xhdd, 1xdvdrom.

Not exactly power hungry.

Looking to answer your question now gives me the answer I need on what fan.
http://www.overclockersclub.com/reviews/atrix_500t/ shows it to be a simple 2 wire 12v fan.

As much as a new fan would be better I cant quite afford circa 50 squid at the mo.

Nice mod Tealc, I might look into doing just that - putting a temp controller inside.
Can you suggest one - a circuit etc?
I'm thinking something like one of these.

One of these fans is what I was thinking of.

Or perhaps one of these
I have the arctic cooling freezer 7 pro on the CPU and it seems quiet enough.

Soldering work is no problem, I have pleanty or breadboard and components available -just have to find a suitable fan.

OK, I now have on my desk an Arctic cooling F12 PWM fan.

I thought I had bought an ordinary one to do the job simply.

So can I simply add this and run it with fixed voltage or do I now need to make a pwm circuit?

Oh hang on - I can put this in place of the rear case fan which is an ordinary 3 wire one and put that in the PSU.

Problem solved.

No idea at the mo - its in my coolermaster case and I cannot hear it. its a 3 wire one.

I can daisy chain the pwm ones so can put this new one at the rear of the case and use the current rear one in the psu.

When I get a round tuit. I have one of those in my watch list on ebay lol
