Ok, thanks for this guide.. I guess I might do this later on, I currently use the Corsair TX650 v2 wich has the 0 RPM fan if under 30% load thing. But once Im done with my build I will see how much noise the PSU fan makes and if to much, will replace it!

Wonderful guide, my only gripe is the volume of your voice with the distance away from the camera, quite quiet but none the less a great guide.

Nice guide, I'm going to try this with my Corsair GS800, because the fan control mechanism isn't working correctly and because of that, the fan doesn't spin fast but produces horribly loud coil-whining.

Just RMA it and get the 2013 Edition if it's still under warranty?, it's a known fault of the models before the 2013 edition.

I've been thinking about doing that, but RMA is a bit time consuming (and I need my pc almost every day) and fixing it yourself is also a bit more fun. My local retailer also usually returns you the exact same product that you bought under warranty, so chances are the new psu has the same error.

While I love taking stuff apart, this is one thing I won't do. First thing I was taught was don't open PSUs or CRT monitors

This is an awesome tutorial. :D I just found it. 

I recently (like 2 months ago) tried to dye my Noctua fan. It failed miserably. Rit Dye doesn't work anymore imo. Though I used the powder and not the liquid dye, I used double the recommended amount and left it in the water twice as long but it still barely changed color (it's slightly darker). I was going for black.

Anyway, in doing this, I burned the cable insulation half way down the wires, and I broke the 3-pin header. So now it's only half the wires with copper sticking out, but the fan still works

I will try putting this fan in my PSU if possible. It's an NF-F14 though, so I doubt it will fit. We will see if I can figure something out (zip ties). :P

Depending on the model of PSU you have, you could have a 140mm fan in there ;)

It's a 120mm fan (Thanks @Whaler_99). 

Zip Ties it is.

I have a question:

I have a Antec Neo Eco 400M (low-mid range PSU) and I'm going to buy a Akasa Apache to replace its fan.

Can I pass the 4-pin fan cable out of the psu, connect it to the motherboard, and leave the psu fan header with nothing connected? Will the psu work as normal, or try to prevent system start because it doesn't detect a fan connected?

i did this on an old spire psu and it worked. but then be sure to set a fan curve based on combined load

I figured that I would share my success story real quick. So I decided to get a NF-A14 PWM for Corsair TX V2 850W, run the fan connector to my motherboard and it worked great! This way I can monitor the fan speed and adjust it using the rudimentary fan curve in my BIOS.

Would I be able to use, instead of soldering, luster terminals to connect the wires to eachother?

Yes.

Nice :)

 

I did the same thing on my latest desktop build: route the entire fan header to the motherboard for absolute control :)

Did you actually need to cut the cable on the NFF-12? From the looks of it you could've just matched the pins while using the 4 pin connector from the other fan. Like cutting a fan extender in half for instance?

The recepticle on the PSU's PCB has edges preventing a wrong connector being attached ;)

I'll have you know that my ghetto CX430M still hasn't failed. :P Now it's in my sister's computer that I gave to her.

How to change Computer Power Supply FAN PSU FAN

https://youtu.be/G8th7FQmgfs


Its hard to focus when you have a noisy computer running next to you.

Behold the solution is available to you now
Change to Noctua NF-A12x15 FLX 3PIN FAN.

Silverstone SFX_L PSU are notoriously known for Imbalanced Rotors, when running in low rpm and vertical position they make galloping noise.

I tried 3 different fans before I bite the NOCTUA Bullet.
Silverstone SST-FN123 12015 - Made Grinding Noise
Corsair 12025 FAN - Too big to fit in Power Supply
OEM FAN - Made Annoying galloping Noise
