I have connected Amd cpu fan with usb cable, it's 12V fan that now runs at 5V, it stands above cpu, i have made a hole on the upper side of Khadas Vim case.
Although the fan doesn't ran at full speed, it makes a big difference when running Linux, i can finally have more apps or tabs opened in it.
For now, only thing i have noticed that it's hard to play yt videos, temperatures do rise up and Vim is struggling to play videos, but this is hw acceleration problem.
They didn't rise as quickly as before, but eventually the cpu will get much hot when using yt, i have exited when it reached 60°C.
Most of the time the cpu was between 35-50°C, and that's ok, i'll live with it before official fan becomes available.
And Balbes, you don't know about any backup app, i know i am boring, but i want to be sure!
