I got a VIM1 and put it into that after market aluminum case from (i think sweden) its a passive case with a chip pad you mount the board to, it runs way to hot for my liking so i wanted sit a fan on the case which is working ive already seen the temps go down.
Right now i have it plugged into pin 1 and 21 but the fan has 3 lines i was wanting to hook it to 4,5, 6 or 5, 6, 7,
The lines on the fan are ground, 5v and i believe the rpm sensing so if i hook the sensing line to the I/O pins on the board will it hurt anything?
What is HUB_DP1? and what is HUB_DM2?
