this is good advice "half Power"

also, I use a 24 volt dc large size fan (about 5 inches) 
run at 12vdc it runs quiet, and moves enough air to keep things cool.

maybe at half speed, the fan will last twice as long???

heat will kill a radio fast.

A GE mastr II base station makes a nice repeater, I have picked one up 
(LIKE NEW) for $250 with a 100 watt PA.

these are GREAT repeaters for the Money!!!

A kenwood TKR-850 make a nice small repeater, but more money!!
I have bought them as cheap as $650 and as much as $1000.00
