Replacing PSU fan with Noctua NF-P14 FLX 140mm fan...?

post #1 of 22
Thread Starter 
I have a Corsair TX650 PSU, the fan on it is very loud (out of balance, I can hear it vibrating in intervals) and recently it has been making a ticking noise. So I was just wondering if I could replace the fan with a Noctua NF-P14 FLX 140mm fan? I want to go with the Noctua because I have the 120mm versions and I know that they are very quiet while still moving a fair amount of air. I have a few questions tho:

1) Will the Noctua provide enough cfm to cool the PSU during load?
2) What sort of fan connection does the PSU have? (3-pin, 4-pin...?)
3) I'm not sure what it is called but does the TX650 have any kind of protection so that it doesn't hold a charge when I'm working on it? Should I leave it off and unplugged for a few days before working on it?

EDIT: I am watercooling my cpu and gpu so there isn't much heat inside the actual case (it is around 30c during games), and I have a 650D case so the PSU is pulling air in from the bottom of the case (in case that helps with determining if the noctua will work ok)

Its possible your blade just needs reseating onto its hub, they can work loose in transport, try gently but firmly pushing the fan onto where its mounted it might help a touch! otherwise, considering your watercooling, i think the noctua would make the job !

And The PSU Should Not Hold the Charge for more then like 1minute .. so after an hour or less it will be completely safe to change your fan !

Awesome, thanks. I just opened up the PSU and the fan has a 2-pin connection. Do I but a 3-pin to 2-pin converter or can I somehow re-wire the fan myself?

Since it's a simple 2Wire.... I'd simply hard-wire , solder & shrink wrap it. There is not a better way.

450


Easily done:
1st....slide your shrink on
2nd....strip - twist - solder




450


3rd and lastly....slide tubing over joint and hit it with heat [heat gun or Bic Lighter]

Nice guide Chester and video justanewguy. Do you have to solder the wires or can you just twist them together? I don't have a machine to solder
