What would be the best way to control fan speeds in my computer? I have been looking at the NZXT Grid+ and the NZXT Sentry 3, I am wanting to set up the fan controller, and then leave it (so I don't have to keep manually changing the fan speeds). I have two 92mm fans and two 120mm fans. My motherboard will only allow me to control the speed of one of the fans, and speedfan doesn't work. Any other fan controller recommendations would be appreciated, I am wanting to spend as little money as possible.
