PSU fan replacement

[NewHopeTech]

I have an EVGA 750 B2 power supply and the fan is by far the loudest thing in my computer. According to the EVGA website it uses a 140mm fan so I am thinking about switching it out with the Noctua NF-P14s redux 90 but I was wondering if that fan is powerful enough for a power supply. Is it?

It's a lot harder than what you think. Usually they're custom designed fans. Linus stated going through a power supplies internals is very dangerous and could possibly kill you. I have a 500B and I don't hear any noise from it. Just RMA it or something.

I doubt it is louder than its supposed to be. When compared to my computer which only has NF-F12s with LNAs it is loud.

it is a pain in the ass to replace a fan on a psu. plus you need to know how to safely discharge the capacitors if you dont it could easily result in death. dont mess with a psu unless your skilled and have experience with it.

Ideally the more pressure oriented the fan the better inside a PSU, something like the NF-A14 are a better option. Most also use a two pin system so you will require an adapter like this below:

note the regular safety stuff when opening a PSU, to unplug it and cycle the power a few times by pressing the case's power button and letting it sit for at least 30-60 mins before opening. When open be aware of the contacts of the capacitors and to not short them while working.

I actually have a spare NF-14 lying around, I'll use that. Thank you and I'll look into proper care and how to safely discharge the capacitors before thinking about opening the psu.
