In Figure 4, you see the front of the cooler. The four heatpipes are close to each other at the base, and spread at the top of the heatsink.
In Figure 5, you see the cooler from the side. Since both the fins and the heatpipes are in direct contact with the base, the heat is transferred not only using the heatpipes, but also directly.
In Figure 6, you see the rear side of the cooler. The fan uses a three-pin connector, meaning that the fan doesn’t have PWM speed control. Remember, however, that this CPU cooler comes with a Fan Mate 2 speed controller, so you can set the fan speed manually.
