This really is a very good idea. Solid state's worst enemy is heat!! I have
several 12 vdc fans from old computer dead power supplies that work great.
The main idea is to increase the air circulation over the heat sink fins. I
shape a cut-up coat hanger to form a bracket to support the fan in the back
of the rig (OmniD, Corsair, Omni 5 & 6, etc.) and I use the 12vdc aux
output on the back of the rig, for the fans power source.
