Im more than rusty with this, but tonight im bulding a gaming pc for the brother and i came to a mind block.

The fans I use are 3 and 4 pin noctuas and i need to connect them to the psu>at max speed all the time (no space on the motherboard left)

If im not mistaking i need to connect the fan cable to the provided adaptor by noctua>>



and connect that to the molex (which is a 3x molex on one cable) >>



And that goes to the power supply. Is that all good guys??


If everything is ok up to this moment guys,my next problem is that my new power suply (a seasonic prime 850w titanium) only gave me 1 of these 3x molex to psu cables and i have more fans!!
I have a unused cable set from a old 2012 corsair hx1050 that has the same cable.Is it ok for me to grab it and use it on the seasonic psu or is it not recommended to do this?

Im itching, but i will wait as i dont want to fry a 3k pc.




Or maybe I have to connect them like this on the existing cable?

Yeah you should be fine. You could spread them across all three or do 2-3 on one and the rest on another. I wouldn't put all 4-5 on one though
Thanks mate XD

A small embarrassing question.I have two 4pin fans that sadly will need to go to the psu too.Since they didnt provide a adaptor i will have to buy one. I was looking at this thing:

https://www.amazon.co.uk/Phobya-Y-adaptor-4Pin-Molex-3Pin/dp/B005EGL4S2

Its a 12v one and can howd my two 140mm 4pin fans.What i dont know is, if I connect the 2 fans to this, will they divide the power and not achive the 12v each? Maybe buy 2 cables to be sure?

Apologies :\

Yeah you should be fine, they should both get the power needed
