not totally true.
there is a very easy way to change fix to variable speed. BTDT.
1U and 2U HP/Dell servers use variable speed fans, you hear them at full speed
when you power the server on.
The problem is that the noise of an "idle" 1U or 2U server is far greater than
the noise of a 5U server for three main reasons.
1. The small servers have less airflow space, so if you want to move (say) 1
cubic meter of air per hour you have less space, so you must increase the speed
of the air
2. The fans are smaller, so the blades must turn faster to move the same amount
of air
3, Small servers have smaller dissipating area/volume, so to exchange the same
amount of heat you must increase the airflow speed.
