I'm quite sure they already used and infrared thermometer and tested it. It should work if using the proper CFM and dm rating. Yes blowing forced air onto equipment will lower the ambient temperature at which the equipment operates. Many radars and complex equipment systems may continue to operate uponin losing air conditioning in an emergency with the use of fans in close proximity. Many times for days. Remember those huge equipment racks with racks of equipment modules etc. What sits at the very top of them? You guessed it, fans.
