Additional fan on EGPU CASE
Is it possible to run synchronized with video card ? Otherwise i have to add on/off button to prevent unnecessary noise.
I would imagine if you got a pwm fan splitter cable, you could use the graphics card's fan header to control the case fan, but only if the GPU's fan header isn't proprietary. But you could still tap into the pwm pin. It's been done before and you can read about it here.
