Frequency Plots
50% Fan Speed
The max values >1KHz frequencies should be ignored since they probably are from external factors. The higher average noise output is in the 200-500 Hz range.
75% Fan Speed
Increased levels in the 250-500 Hz range. According to several studies, too much noise in this frequency range leads to muffled or boxy sound. Thankfully, this is not music but fans spinning.
100% Fan Speed
With the fans spinning at full speed, the noise is increased in the low midrange from 250 to 500 Hz.
Signal Recordings – 50/75/100% Fan Speed
I have recorded the signals shown above, but please keep in mind that I’ve enabled Automatic Gain Control (AGC) to do so to make it easier for you to reproduce them. The provided recordings are only offered for aural identification purposes.

Is 800fx much better than 800dx? There is something like 60$ diference between those two cases I wonder is 800fx really worth spending more.
Nope it isn’t. Some lighting stuff as I remember and other small improvements.
