My PC consumes well over 200W of power when running hard, My graphics subsystem another 80-100W or so when stressed. almost all of this dissipation is confined to a few very small areas, this is a heat problem. My i7 CPU with a big heatsink and fan on it stabilises at 57C when working hard (~35 degrees C above ambient temp) My K3 with Sub consumes under 15W in receive, the front panel temp stabilises at around 14 Degrees above ambient temp after being on a while. this is not a heat problem, no matter how you look at it. If it makes you happy, cool the case externally. the side panels are in good thermal contact with the internal screen between the Front panel area and the rest of the radio so this will also lower the temp in the front panel area. Cut slots or holes in there and you will have a new set of issues to deal with, namely EMC issues with digital trash from the front panel DSP / CPU areas getting back into the receiver. -- 73 Brendan EI6IZ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
