I am building a new machine. I believe I screwed up in my case selection. Fractal includes 3 fans with an integrated controller. Unfortunately the fans are all 3 wire and their "controller" is a simple 3 voltage fixed divider. Switch for low/medium/high.
Looking at the documentation for fan wiring, it appears that the pins functions starting at pin 1 are gnd, power, speed sense, and PWM control.
How will the controller on a P8Z77-V Deluxe board handle these fans. Can they actually be controlled in respnse to some measurement of temperatures inside the case or do they need access to the PWM signal? Do I need to replace these fans with a 4 wire version for proper control?
If the motherboard controller can control the voltage on pin 2 in relation to the speed that might work, but I really am not sure.
