F-Drive R12

Hi, we just finished an installation in a community center where we installed 31 Pro One-Cell Small and 55 Arclamps. The F-Drive is equipped with 8 cc150 cards and 3  Arclamp-150 cards. This gear acts as the main lights for the auditorium, when anybody enters the room and hits the switch the light turns on. So the F-drive has to stay on all the time. Even with no load (lights off, which means about 90% of the time) the fans are running on full speed and are very noisy. (I`m not talking about the meanwell psu units whitch we replaced because of they`re terrible noise). The question is: is there any way to get the fans temperature or load controlled?
