I don't think so. The only time I've seen it is when there's a mismatch, but even then I believe it doesn't give specifics.
You can, however, get the part number of the fan.
X460G2-24t-G4.2 # show fan detail
Slot-1 FanTray information:

This one happens to be a Front->Back airflow model. What model(s) are you trying to look at? I'll see if I can find the part numbers, if that will help.
