The Phanteks XT Pro series supports up to 10 fan locations, including options for both 120mm and 140mm fans. These fans are typically placed in the top, front, midplate, and rear of the case. However, specific details about the fan connections, such as whether they are connected via PWM, are not provided in the available data. Generally, fans in PC cases can be connected using PWM or DC voltage control, but this depends on the specific fan models and the motherboard's capabilities. For precise information on PWM connectivity, consulting the case's manual or contacting Phanteks directly would be advisable.
