I updated my fan control script to keep a log of the amount of time that the fan is 'on', and then went a bit nerdy (nerdier?), and worked out the duty cycle for several different set temperatures. So on a hot summer's day, inside a hot amplifier, my RPi4 4GB running LMS and Squeezelite sits naturally at about 67 to 68 degrees. My little fan running off 3.3V can pull it down to about 52 degrees
[image: http://www.cjh.me.uk/MyPhotobucket/cache/DIYHifi/Fan%20Duty_480.jpg] So on the basis that 68 degrees is still some way short of the 80 degrees that causes throttling, and is therefore considered safe (?) by the manufacturers, that's where I've set my fan control. This means that it's not being triggered under normal conditions, but if the load on the Pi increases then it kicks in. ------------------------------------------------------------------------ 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
