What options for adding a fan at the pro version ? What you do for this for cooling ,do you put a fan and always have a steady speed or with any control you manage to increase the speed as temperature rise up ?

I just run a small PC fan powered by a power pack from an old router. Works well and keeps the radio cool.

F4JFG What dimensions is this fan ? Should have 2 wires or 3 .If I need to put any external speed control ,i look for noctua
