I believe my power supply is ok to add 2 fans.  The only pins I have available are a 4 pin (molex?) and a two 3x2 pin ones.   I'm not sure what those are called.   Where will I be able to connect my fans.  Thank you.

 

PS.  After posting this, I noticed i have a 3 pin SYS_FAN on my mother board I think I can plug into.  Should this be the air intake or the exhaust.  Thanks so much!

What MoBo do you have, the specs can be checked to see what it has.  Fan direction is done by the direction in which you mount it, you can tell by the blade configuration which way it turns.


If you don't stand for the flag then you will fall for anything!

You can buy molex-to-case fan adapter wires.

Thanks so much.   One of my fans will connected to the MoBo and the other to my power supply via the Molex connector.

Generally...a fan at the lower front of the case...pulls air in.

 

All others are blowing out on my cases.

 

Cool air is heavier, so that makes sense to me.
