I agree w/ what's been said so far. Either engine fan or possible boost/intercooler leak. If the intercooler it sounds like a "wooshing" or sucking and only happens when under acceleration/load. If the eng fan, the water temp should have come up to a "X" point on gauge, fan kicks on and temp should've come down. Sometimes the fan will stay on till you crest the hill, others it will cycle depending on length of hill. Like what others have said too, the eng fan sounds like a jet under the hood.
For farts and giggles, next time your in city traffic and at red light w/ semis around, listen to hear if you hear sounds similar to your when they take off from a dead stop on warm/hot days. Chances are their eng fans will kick in briefly as the sound will be greatly louder than normal diesel sound.
