Is your colling fan attached to pins where you controll when the fan turns on? 

Is it on all the time? 

I have one of those cases with a fan attached and the fan power is attached
pins 3 and 5.

It works great for cooling the pi, but the fan is cheap and its loud. I think I
will attached a pulldown to it and setup a script to turn on the fan only if it
needs to be cooled.
