In Figure 7, you can see the three-pin fan connector, with three pins, i.e., without PWM speed control pin. But this fan has a speed control potentiometer that allows you to manually control the speed. The only problem in this system is the fact you need to open your case to change the rotation, because this potentiometer wire is short. It is a pity this fan has no automatic speed control.

Removing the fan we can see the solid heatsink with aluminum fins and a classic aspect.

A unique fan is the trademark of ISGC series, with recesses on blade tips and a clean white look.

The heatpipes do not touch directly to the CPU, but the copper base has a mirror-like polishing, as you can see in Figure 10.
