I recommend hardware _without_ need for fan as Freedombox.

A fan is a moving part - often the only one - likely wearing out much 
earlier than the rest of the device.  In my experience, fans do not fail 
but becomes more and more noisy over time - especially tiny fans.

One way you can try limit the use of the fan (other than underclocking 
the device) is to lower ethernet speed to 100Mbit or maybe even 10Mbit.  
Depending on your usage pattern, there is no real gain from higher speed 
but I suspect (with no hard data to support it, though) that its effect 
on heat is noticable.
