Sounds like someone wheezing and whistling in the corner, which is quite annoying as the Pis are in my home office so I'm hearing this all the time. As the temperature seems to hover around 50C most of the time, the fans come on a lot, sometimes for just a half second at a time. One (possibly both) of the Pis has started intermittently making that high pitched noise on and off, possibly in association with the fan being triggered frequently due to the settings not working. I've done a bit of checking, turning one off at a time, and they both appear to be doing the same thing with the fans after the same software updates today. It seems that the fans now come on when the temperature hits 50C - which if I think is maybe the default if not overridden? Since then, both of the Pis appear to have stopped controlling the fan according to the above settings. I did that today as usual and there were a few updates installed. I ssh in and run apt update/upgrade a couple of times a week. (I've everything updated to the last version)Ĭode: Select all # to regulate when the fan comes on and offĭtparam=poe_fan_temp0=60000,poe_fan_temp1=65000 ![]() Or there is an alternative way to do this since september with this thread was published -? need to ^c, as not coming back to the prompt Speedy Title overlay with custom text and colors - great for any video - dynamic text animation - in an infinite future race loop scene Surprise your. ![]() Ignored it, done a chmod +x and copied over to /boot/overlay (backed up first).Īnd sudo dmesg -w, doesn't provide anything.
