I just think it is your clutch fan actually turning on, its getting hoter now and they are starting to engage agian, Mine sounds like a UPS truck!!! Try to just remove it by takin off the four bolts connected to the water pump pully, pull the fan off bolt the four bolts back on so you pully doesn't fall off, and see if you still hear it.

if your synchro's were gone or bad you would have a grind when shifting into a gear. I killed my 5th gear synchro racing a bike last week and it didnt make any weird noises. It just grinded every time I put it in 5th after that. Sounds like maybe a clutch/throwout bearing problem.
By the way.... I won
