cooling fan

Howdy y'all, starting a build, and I'm concerned about heat from my amp given the location I've got planned out for it. It'll effectively be sitting in a cabinet, and I'm planning to cut a hole out in the top and using two PC fans as exhaust fans to try to keep it cool. My question comes down...

This is my headunit... along with my white accents.... You can also see the switch above my lighter... thats for my cooling fan on my amp.
