That doesn't move any air across the heat sink or solid state devices that need the air. The air that comes out of those vents starts at the fans in the rear. BillK3WJV

They are running on a 19-volt supply at a slow but effective cooling speed and are very quiet (drawing air upward). During normal CW rag chewing the main fans do not come on -- a vast improvement for a few bucks. When you go portable, just leave 'em home. 73, Roy K6XK ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to k3...@yahoo.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
