Pretty simple, it has oodles of power to cool the pilot probably up to 60c with both fans running. If one fan stops for a break outside gliding distance to an airport its probably plowing potatoes while the pilot sweats heavily. There was an ATSB enquirie into why Navajo's could not maintain height when they should following an engine failure, was in the 70s I think, will have to dig it up, although not sure where to dig up the old BASI reports from ancient history anymore.
