Excessive fan noise from seats ?

Have you guys noticed whenever the ventilated seat fans speed is set to maximum (3 leds on)... it is on the noisy side? I have tried it on the passenger side as well and the noise from the fans are the same.
With the radio off...you can really hear the fans.
Is that the design or just my car?
thanks.

I would think that is the way it should be.

Unless the fans are more powerful than the 220 version...but still, I would think one should not be able to hear it from the seats. Unless the radio is on, it is sort of annoying and the noise level goes up or down according to the speed I set (1-3 leds).

At first I thought the noise was from the engine compartment...which I was concerned at first.
At least I know you guys are hearing it as well...so it is nature of the beast.
I will try adjusting the side bolsters like the other member mentioned to see if it helps.
