There is more to an FET spec that just current and voltage figures. Some other ones are Rds_on, gate capacitance, slew rate, temperature coefficient, etc. Slew rate alone (which is just how long it takes for the FET to switch from 0 to max or vice-versa) can make a big difference in temperature.

BTW: I have some more results from running, but want to get a little more time before posting my observations...
