I took the fan off the cooler (the instructions for doing so are given, it's easy, and visually examined the fan. The plastic component with the actual fan blades and hub, pulled off easily. Too easily. Examining the metal spindle/axle on the inside of that plastic hub, I saw it had a notch. I pushed it back into the motor, firmly enough for that notch to click. Resists being pulled off now. Plugged the fan back in, it worked first time.
The problem here seems to be careless assembly of the final components at the factory. The fan is not being pushed properly into the motor; thus it's not engaging properly, the motor can't turn it, and things rapidly go downhill from there. luckily it's an easy fix.
