[1000mp] fan noise on mark v

[WX5L]

I have had my Mark V for about a year now and do find myself wearing my
headphones more often expecially on weaker signals due to the fan noise.
There is a slight purring fan noise from the power supply but the level is
so low it doesn't bother me.

 I guess because of the 200 watt output rating and large heat sink they
needed a higher volume of air movement. I guess it goes hand in hand.
