This fan moves incredible amount of air and it will keep your internal CPU components cool. However since it is a 3 pin connector, your mother broader header must provide enough power to fully power up this fan, in this case 45W. You can always control the speed of this fan with a fan controller. The fan controller channel needs to be 45W or higher in power rating. WARNING : DUE TO THE EXTREME HIGH SPEED OF THIS COOLING FAN, PLEASE EXERCISE EXTREME CAUTION WHEN YOU POWER UP THE FAN, AND MAKE SURE THAT ABSOLUTELY NOTHING (SUCH AS YOUR FINGERS IF YOU ARE HOLDING THE FAN) CAN GET CAUGHT BETWEEN THE FAN BLADES WHEN THEY ARE ROTATING. THANK YOU VERY MUCH.
