Seems like that would be cheaper than stocking alternate part numbers.The fan is inside the power supply right next to the high-voltage capacitors. You shouldn't be near that without proper training.
Last rack switch I bought, no fan was integrated into the power supply. Instead, a blower module elsewhere forced air past the various components including the power supply. Efficient power supplies (which you really should be using in 24/7 data centers) don't even generate all that much heat.
