Not uncommon, older vehicles used belt driven fans without any variable speed using more fuel/hp - steadier engine temps, newer belt driven fans had thermostatic or clutch type fans that were driven by fluid clutch, hotter the air going across fan, more air it would pull, still not ideal but less hp. Newer vehicles utilize electric, hydraulic and belt driven fans using various methods of use only when needed. Example - electric fans turn on/off - on 220 and off at 185 (again example temps). Driving down the highway, most fans do little if any work as air moving through the radiator is sufficient enough to keep the engine cool. In traffic and/or lower air volume situations, temps will rise and you may notice it on the gauge. However if your engine temp is too low, your thermostat is most likely defective / stuck open and could result in longer warm up periods, internal engine deposits/condensation, excessive fuel usage (colder engines require more fuel), driver discomfort in colder climates, or overheat if stuck in a position whereby not enough coolant can pass under higher speeds etc. Most newer vehicles monitor engine temps and will pop your "service engine soon" or other warning indicator lamp on if they detect engine temp too cool and hopefully - too hot.

What is minimum speed on freeway?
There isn't a minimum speed per se, but if you are impeding traffic you can be ticketed. It isn't safe to drive slow on the freeway, other cars may not judge your speed correctly, it's more difficult to merge, and it makes other drivers very upset, which makes them more dangerous and aggressive. So if you can't drive the speed limit on the freeway, stay on surface streets or take the bus.
