Hi, This is my first post here. I plan on building a new system based on an Asus P6T mobo in an Antec P193 case but I understand very little about the details of how cooling works, particularly CPU cooling with PWM-controlled fans and all that. I'm guessing that the 4-pin connector from the CPU fan to the mobo effects the PWM control of the fan, so am I right in thinking that the mobo controls the CPU fan speed in accordance with the CPU temperature as monitored by the mobo? Also, can anyone please point me to any detailed info about how coling fans are controlled from the mobo? TIA Johno
