Reversing fan direction

[Warthog]

How can I reverse the direction of this slot fan "system blower", which is really and exaust. Is there some way to reverse the wires?

Thanks.

Yes, switch the + and -, it will switch polarity and run the fan in reverse

Thanks, I thought it might be that easy after I read your +/- advice, but it didn't work. The two pins pop right out of the plastic case. I tried every combo, but couldn't get it to run backwards. It would run slower, but not backwards.

I think I am going to have to cut holes and put fans in the top and side of my case. Does a normal jigsaw work, or what would I need?
Thanks again.

That makes sense, cause I'm pretty sure blowers dont work in reverse

if the fan comes out, try turning it upside down maybe?

dc blowers like that are electronically controlled like muffin fans (your typical computer fan). The polarity cannot be reversed unless you want to mess with integrated circuits

Blowers are really only designed to work in one direction anyways...
