Paul. There was a mod doing the rounds which involved adding an extra fan on the back plane. The reason was that there are two heat producing modules, the PA unit and the power supply side by side. It was well known that the main heat sink across the back and the single fan cooling the PA unit still resulted in overheating. My one has been converted with a separate bolt on panel with the extra fan colling the power eupply module.
