I'm planning to build a water cooling system using the asus maximus viii gene motherboard wich has the dip5 including fan xpert 3. so my question is can i select gpu as source for a fan so that the fanspeed is based on the temp of the gpu? And is a 360 19fpi rad push and pull 2200rpm enough for 6700k and 980ti? Or is sth like the Accelero Xtreme IV from arctic better?
