Question about FAN on TrackSpot

The fan on one of our TrackSpots is starting to go. I have come to the conclusion that in order to ensure the longest possible life from our bulbs, good air flow is a must.

Could someone please tell me the specs of the OEM Fans in the trackspots?
What voltage, CFM, RPM, and size ( I assume 80mm ). We have about 40 Intelligent fixtures mounted in our club ( stripclub ) The music is loud so having these things be quiet is not a necessity. I am researching what other fans I could possibly install to help move more hot air out of these fixtures.

I find it hard to believe that I am the first to think about this. Has anyone tweaked with different fans to get improved airflow?
