The clutch fan on the motorhome shut off as we approached Lake Meredith NRA. It has been on since May 2^nd.  The reduced noise level is quite pleasing.  The fan seems to run when we are above 3,000 feet to support the inner cooler, A/C, transmission cooler and engine.  It could have taken a short break around Seattle, based on elevation; but, with traffic and temperatures when we arrived it didn’t.  When it does shut down you can hear the rattle of the diesel, the whine of the transmission and tires and the wind noise.  Doesn’t seem like that much noise should be something to look forward to.  But, it is a relief to only hear the fan run when the radiator needs cooling.
