This is a normal fan control. The temperature sensors are a bit off and it's a little difficult to actually change the fan speed, and the sound these things make every time you press the screen is awful. I ended up ripping off the little speaker with pliers. If you set the fan to the lowest speed, an alarm will be triggered after 15-30 seconds and the controller will definitely increase the speed of this fan to the maximum. The maximum fan speeds also change daily. It also likes to rotate when screwed into the slot, so make sure it's tight. Also, it looks cool and works, but I will never buy another one.
