"Yes, the fan is probably turning at a low speed"
Could be. But because fans use electricity and manufacturers want to get a good efficiency rating, it is now common for fan controllers to keep the fan powered off completely if possible and then run only at the speed actually required. In come cases, e.g. power supply fans, it is possible to physically see the fans and observe that, indeed, they do not turn under low load.
