Not to get into the air-cooled vs water cooled debate, I can reply to this question. The answer is: it depends.
The hottest bike I ever owned was a water cooled BMW K100RS. When the cooling fan came on (especially when stopped) it was designed to direct the heat from the engine directly onto the rider, especially the rider's left leg (as I recall). That bike would cook its rider on a hot day. I never experienced that kind of heat with my air cooled BMW airheads (R75/5, R100RS) or my suzuki DR650 (oil and air-cooled.)
At one point, I think Honda tried to address this issue on the water cooled Goldwing by having the cooling fan reverse when stopped- to try to suck the heat off the engine forwards, but I think they gave up quickly on that when their new bikes began overheating.
Some bikes are notoriously hot and others don't seem to be.
