I can never tell the fan clutch condition by pushing the fan blades, unless it is very bad. I test my cars (300D and 300SD) by increasing the engine rpm when it is cold and hot (~95 degree, necessary) and listen to the fan noise. I posted detail steps in the past. Search this forum to see if you can find them.
PS: The fan clutch works a little more complicated (or smarter) than you think. I am not smart enough to tell if it is bad by pushing fan.
