The fit was much more convenient that I expected - it slid in between the two ribbon cable sockets, touching both but without forcing them in any way. I think you're right - any serious continuous load will require active cooling if the aim is to avoid throttling. Fortunately for this discussion, LMS+Squeezelite don't seem to represent a serious continuous load. And I suspect that even if throttling does kick in, Squeezelite would be unaffected and LMS only marginally, if at all. For a bit of fun I logged the CPU temperature on the 4B in my amplifier for a 24 hour period: [image: http://www.cjh.me.uk/MyPhotobucket/cache/DIYHifi/RPi%20Board/pcp_cpu_temp_18JUL_640.jpg] I can see: - the gradual cooling of the amplifier after it was shut down at the end of the previous day. - a brief spike at 2am where the cron script runs to take a backup of the SD card. - a slight rise in temperature just after 10am. I think this could be when the sun hits the amplifier for a short period, and then as the sun moves on the amplifier cools down again. - a very clear warm up just before 6pm, when the amplifier was powered up. During the evening the amplifier variously played Squeezebox music and TV sound, and there's no clear difference in temperature - it just sits at around 65 degrees, which must be dominated by the ambient temperature inside the amplifier. ------------------------------------------------------------------------ chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=110690 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
