Hi! If anyone needs it i am going to add an Aquacomputer quadro to my Dell M4800.
What is it?
It's a small fan controller, the smallest i could find.
I'll try to desolder unnecessary components and fit it somewhere inside the laptop.
Why?
Because Linux have lots of problems with Dell's fans and i would like to control them more fluently.
I'll grab the low voltage usb line from the expresscard slot and add to it an hopefully good step up converter to get 5v out of it. i'll use it for the data line of the controller.
then i'll power it from the slim sata connector of the DVD. I bought a cheap caddy not to damage the connector on the motherboard itself.
Hope everything will work and i'll be able to cool my laptop better and with less noise
