AP181 uses industry standard 3pin fan connector, so it will work with most fan controllers, motherboards, and other devices that use voltage regulation to control fan speed.

The starting voltage for AP181 at low speed setting requires about 10.8V, which some fan controllers may not support properly. So when connecting to fan controller, it is best to flip the case’s fan speed switch to high setting to enable lower starting voltage. At 5V for example, the fan speed will be at around 500rpm, which is nearly inaudible.

When connecting to motherboard for fan speed control, if AP181 appears to have trouble starting, it may be due to motherboard detecting low temperature and supply too little voltage. To solve this problem, please change the motherboard fan speed or temperature setting from within the motherboard BIOS or flip the case’s fan speed switch to high setting.
