Hello,
I'm having trouble with my 12v radiator fan as the battery keeps depleting and need my cooling system to run continuously. Would it achieve the same result if I hooked my radiator to a regular exhaust fan like the ones used in restrooms?

 
While technically you can, we have to wonder why?
Most cheap ones move little air compared to their noise.
It would be more practical to run your 12v fans off of your computer power supply. Try a molex connector for 12 volt if your fan pulls more than a 3/4 pin fan connector can handle.
Molex also has 5volt and 7 volt available if you mod the plug so 12 volt is positive and 5 volt is negative.
