Lots.  HP does not seem to take acoustic noise level in to consideration 
in its designs.

I have an old HP5245L.  The fan is quite noisy.  When I upgraded to the 
more modern HP5345A counter I was disappointed to find that its fan is 
even louder.  The HP5335A also has a rather noticeable fan.

But they are not all bad.  If I recall correctly the HP5334A does not 
have a fan and some of the other small HP models do not.  But if noise 
is a consideration, you need to check the specific model to be sure.

I have several pieces of HP (and other brands) of test equipment.  A lot 
of it only gets turned on when I actually want to use it.  It is just 
too noisy to leave on otherwise.
