Hi @Johnny, I’m sorry to hear that your LarkBox fan stopped working…I guess the fan may have to be replaced.
Mine has the same fan behavior as yours; starting/stopping too often.
I am expecting to have the same problem as yours sooner or later because I keep the fan running all the time…please refer to my post at “Larkbox fan noise and temperatures.”
Since I don’t think I can get a replacement fan from CHUWI when my fan dies, my future plan is to cut open a big hole and put a 5cm fan on top. I need to be careful with the Wi-Fi antenna, though.
We can get 5-Volt power from the USB port using a USB cable (need a little modification). If 5-Volt is not enough, I will use a 9-Volt trickle charger to run the fan. ★9-Volt feed to the 5cm fan is quieter than the original fan noise
