Unlikely. The same fan model is installed on my other main-board
(Gigabyte with it8728) and its possible there to bring down the fan to
0 rpm with pwm set to 0.

Set to [0-4] => fan spins up to maximum rpm (~2250rpm)
Set to > 5 => fan spins at desired rpm (~600rpm upward)

No problem for me. This box runs all the time with no suspend mode
anyway :-)
