The StarTech Socket 423CPU Cooler with its 2cm fan cooling fan is a combination heatsink and fan designed to cool Pentium 4 processors. It sports an extra-large heatsink with enough cooling capacity for even the newest and fastest processors. A quiet running 6 cm brushless ball bearing DC motor coupled with a high-efficiency blade design is capable of moving 23.2 CFM (cubic feet per minute) of air. Power is supplied to the fan using a 3-lead TX3 connector that plugs into the motherboard and allows the system to monitor fan speed and operating status.
