[Elecraft] [K3] K3 fan noise, part XXLIV

[Joe Planisky]

The topic of K3 fan noise seems to come up every now and then, and  
each time it does there's a chorus of people who say the fans in their  
K3 are absolutely silent, and an equal chorus of people who say the  
fans are clearly audible.

I'm in the latter camp. I hate fan noise and I can clearly hear the  
fans on my K3 even at the lowest speed.

I recognize that people's perception of noise depends on many things:  
other ambient noise in the environment, personal hearing acuity, how  
the equipment is placed on the desk, what kind of surface is  
immediately behind it, etc. etc.

However, I'm also wondering if Elecraft has changed brands or models  
of fans from time to time.  It's possible that some brands/models  
might be quieter than others.

The fans in my K3 are made by UTEC and have model numbers of

     AT6015L-12L2B-ND2 and <same prefix>-ND5

I would be interested in hearing from others who care to check the  
brand and model # of their fans, and whether you perceive them to be  
quiet or not.

It's probably best if we don't clutter the list with fan brands and  
models, so please reply to me directly and I'll post a summary of my  
findings in a few days.
