New PSU Fan , not spinning

[HeyNowYourAnAllStarGetYourGameO]

HI,

long story short the stock fan in the corsair 750 tx power supply was loud so I thought i would just upgrade it. I bought this fan -

https://www.amazon.co.uk/dp/B00L64NST4/ref=twister_B00M0H2LH6?_encoding=UTF8&psc=1

It works fine when plugged into the 3 pin sockets, when i soldered the 2 pin header onto it and plugged into the PSU, the fan didn't turn on, my soldering is fine as soldered the 3 pin and 2 pin back on to their original components and they worked fine. Is this fan compatible with the PSU? would it work if I bought a 3 pin to 2 pin adapter instead?

All help greatly appreciated

note: i am aware warranty is voided and my soldering and what i soldered to what seems fine

Thanks,
Calum

which wires did you use? are you sure you got the +and - correct. using the wrong wires wont work for sure

you need an adapter like this one in order to make it work

hope you manage to fix it

edit: just a note, these fans arent very quiet... actually pretty loud.
grab something from noctua i doubt you look at the leds on the bottom of your case.

Are you sure that adapter is what i need, because what I can tell from the picture all it does it exactly what I soldered. It just cuts off the third wire.

I believe so, the wire on the outer side with a line running through it as negtive, and the middle as positive

UPDATE: fixed , had a faulty resistor on the inside of the fan, soldered new one.
