Here are pics of my ghetto fan install. I salvaged a fan out of my old pc power supply. I tapped the power jumper that goes from the power supply board to the dvb s2 8psk tune card. The yellow and black are +12vdc. I don't know if the powe supply has enough extra amperage to run the fan and the rest of the receiver? So far so good the fan pulls 0.17A. Here are pics. The fan is blowing air into the unit blowing almost on top of the CPU heat sink. The air then finds it way out the rest of the vent holes. Fan is quiet.
