    And some more info....You cant measure the DC voltage or current out to the LNB without loosing signals, attaching a DVM or current meter without a very special interface with shut down the system, and you may get a false reading.

    You may get a DC voltage reading at the end of the coax, or at the LNB input on the receiver, but this is an UN-loaded condition, and will give incorrect readings, all it will tell you is that there is not (or is) a DC short somewhere in the system.

    I use a highly modified receiver to do this, this measure's the active system voltage and DC current draw of the LNB(s).

    Absolutely right Terryl. I'd invite doubters to pull the cover and feel the heat sinks on the processor and turbo module.
    Hot! Once you inject the correct voltage into the lnb, a vast decrease in temp on the heat sinks.
    FTA lnb's are fairly power frugal. DN's, hogs!
    The T5 has a header (pair of pins) to allow you to use a small fan inside. I use a repurposed 386 processor fan.
    Geeky ones like me. For my LB8000 I traced the display and found the pin for illumination. Used a small solid state relay to power an internal fan which switched on when the receiver is on.

    My audio receiver has a switched AC plug, I use that to power a 120 to 12 volt 5 amp power supply, this runs all the fans (8 total for now) in the stereo cabinet, I build my own cabinets, so this one was designed with air flow, to the HDTV and all the audio, Blue ray and other receivers.

    Takes cold air in from the bottom and blows it out the top, all fans are rated under 19 dBA with a very high air flow, can't hear them at all when the stereo or TV is on.

    Glad we're on the right page. Same thing I have. I was lucky to find a couple of 4 inch fans with temp. sensors. Pretty slick.
    Low volumes on my HT rig, whisper quiet. Crank it up to piss off the neighbors (oh wait...i live on 80 acres) and they ramp up nicely.
    Cool lets electronics live.
