Turning up case fan causing heat?!

I have a very odd problem. I didn't notice this until I got my fan controller, of course, since I couldn't control the fan.

When my PC is at idle, with the case fan off, my CPU is at 38C and my GPU at 43C. When I turn my Tornado up to max, rather than cooling my PC, my CPU goes up to 40-42 and my GPU around 45 and sometimes higher. During games, the effect of the fan is negligible at best. It's a very loud, powerful fan, so I'd like to know, is there something wrong that I can't identify, or should I just take the thing out to give more room for the other components? The fan is definitely blowing air OUT, so I don't have it backwards. The room temperature at present is about 21C(70F) so the air being sucked in the front vents isn't heating it up.

It is in a bit of a confined space, so my only theory is that the air being blown out the vent by the Tornado is somehow getting back in through the regular case fan. For reference, the Sonata 2 case has a plastic vent inside that places the Tornado fan over the CPU fan, and it shoots the air out a different place than the regular case fan (which is still installed, of course, and on all the time.)

Any ideas/suggestions?
 
I have the case fan blowing air out the back, and the Tornado does the same when it's turned on. I don't have any fans blowing in, but air is sucked in the front through vents. I can feel the air going in faster when the Tornado is turned up.

edit: I feel silly, because I didn't know CPU fans blew air on the fan instead of pulling air away. That explains my original problem, so I'll turn the Tornado around and hope that improves the situation.
 
put ur case into some place where have a spacious space that good for the heat spread~
edit : good job ~
