Hi,
When I bought my first RPi4 (I own two, for the time being…), I bought it together the full kit, including the fan shim. When I assembled it, it ran a few days without any problem, the only thing I’ve noticed was that the fan was a bit noisy (it was running full speed).
Then I decided to install the script as described in the getting started, and everything was running, the LED changed colors, etc.
About three or something days ago I noticed that the LED was fixed red, and the fan was stopped. I reinstalled the software, changed the settings (temp ON and OFF), rebooted the entire thing but nothing seems to work. What I’ve noticed was that when I touch the shim, the fan seems to “want” to start, it spins one time and then stops for some moments, then it moves again and stops and so on…
The current setting is 55ºC for ON and 45ºC for OFF, and the board was running a bit hot at 74ºC… I’ve turned off the RPi and later I’m going to test it again. I have default Raspian Buster running, everything is updated and the service indicated that it was active and running.
Maybe the solderless fitting needs a bit of solder?
Thanks!
