The H4 halogen bulb will create a lot of heat, so expect it to be hot when touching your headlight.
Bikes get hot. Liquid cooling is aided by some air cooling as well, but a lot depends on your speed too. 30 miles at 120kph or 30 miles crawling through traffic?
Are you sure the fan was running the whole 30 miles ?
