Can I Just Put a PC Fan into my PSU and not my MoBo

[gidgiddonihah]

So i have this Dell e510 and.... I got two 80mm fans for free (yay lol). The problem is: there are no more slots for fans... So right now i just have them plugged into the PSU and so they are running as fast as they can.

Is this bad? Will i burn out my fans? (Im building a computer in a few months so it wont be long untill i can get pull them out)

Also my fans are positioned so there is a box of fans (PSU, standard DEll 120mm, 80mm, and the GPU fan-XFX 9600 GT 512mb of vRAM). Both the fans are attached to the rear grill so they could pull the hot air out of my stupid case. But i was careless and am now lazy: I put one in way and the other in another way... And now i dont want to fix it. Will i still be able to cool every thing right?

Thank you ahead!

Connecting them to the psu is fine.
If I'm reading that right , you have one as an exhaust and one as an intake, that's not good, both should be installed as exhausts.
