Case fan limit

post #1 of 4
Thread Starter 
Hi all!

In a previous post I noted about putting 2 140mm fans on my side panel. They are working flawlessly and I have both of them setup as intake units.

I also noticed that in the packaging for these 2 fans there is 3-pin to 4-pin connector which I assume means I can connect the fans to the 3-pin end and the other end directly to my power supply.

My question is if I am indeed able to use that connection (3pin to 4pin) and have the fans being powered directly from my psu instead of connecting them on the mobo, can I then use the 2 spare 3pin connections on my mobo to add 2 more small 80mm fans?

And what variable will limit me in terms of power consumption and voltage usage if I were to add those 2 80mm fans?

Please adivse.

Thank you!

yes. mots fans come with the 3pin to molex connector, so you can hook the fan upto the psu incase you do not have a spare 3 pin on the mobo. alot of mobos only have 2-3 3 pins on them.
in shot yes you good to go to get more fans.

When your passing cat gets sucked up or your case starts to hover then you know it's too many If you're out of 3 pin connections on your motherboard you can buy adaptors from 4 pin molex to 3 pin fan header, though they run at 100%
