Hey guys, so I have an Antec 900 case "http://www.newegg.com/Product/Product.aspx?Item=N82E16811129021" and I have a Corsair RM 750w Power Supply "http://www.newegg.com/Product/Product.aspx?Item=N82E16817139055". My Antec 900 case does not have vents at the bottom of the case. I'm not sure if my power supply fan should be facing up or down? What is recommended? Do most people face it down or up?
 
Solution
Usually the fan would face down but in the Antec 900 you have to have the fan facing up.

Okay, this is my power supply. In this picture, the fan is facing down. "http://www.avadirect.com/images/items/PSU-CSR-CP9020055WW_G1.jpg" So if I put the fan facing up, those words are going to be upside down which I think would not be right.

most top mount psu's face fan down and act as a supplementary exhaust. Bottom mounted psu's with grills in the bottom of the case can be mounted either direction, either drawing hotter air from around the gpu and exhausting that outside the case, or drawing colder air from outside and exhausting outside. With no grill/mesh on the bottom of the case you will have to mount it fan upwards. This is perfectly normal and acceptable.
