Tagan Power Supply

My Tagan 480-u15 (the modular one with the single fan on the bottom) seems to suck air INTO the case rather than blow it out. Is this right? Has my fan been mounted upside-down?

????..I have the one that has a fan on each side. It sucks air out, but usually the fans never run fast because I don't put enough load on it. Your's should be sucking air out?
