Finally installed
! Temps and quietness are great (for me), only thing I don't like is the flow and the mess the wires brought but luckily, that can be sorted out, wires will be routed and I'm thinkin of that little grundfos pump.
Also, the fan 'controller' (12V/7V/5V) will be made and installed as soon as I find some more time.
Haaaaaappppyyyyyyyy
