Does the 3705 cooling fan work on Android 9 on VIM3?

I’ve installed the heat sink and fan on my VIM3 which uses Android 9 OS from the factory and the fan is not operating when things start to get hot. Is there anyway to run a check on the fan?

Thanks for any info.

From the brief bit of time I ran the provided Android 9 image, I do not recall the automatic setting being functional. It could be controlled manually, however, from the settings panel.

Hi all, please help, bought VIM3 Pro but in Android system setting there is no colling fan option to control the FAN, what to do?

Hello, V14 is our latest hardware version number. The reason is that the inconsistency between the hardware version number and the software version causes the FAN to work abnormally. At present, the software has been adapted to the V14 version number, but the firmware is still in the testing stage and has not been uploaded. We It will be uploaded to the server in the near future, and I will push it to you in time, and you can download the update and burn it

@xiong.zhang Thanks a lot, the latest version of firmware you pointed solved the problem.
