I just bought a new psu today to power a graphics card I have also just purchased. My old psu had a fan in the back and this new one if orientated in the same manner as the old psu has a fan facing upward. My case is solid at the top(no openings for fans) so I may have made a bad purchase if the psu's fan is suppose to send air out or bring air in. I know that sounds dumb and I am farely new to pc building but perhaps the psu fan draws air upward to be sent out by the fan below the psu? Thanks for any of your help!
