Thermaltake ISGC-100 CPU Cooler Review
Introduction (Cont'd)

Removing the fan we can see how the heatsink looks like, being smaller than the ones used on 120mm fan coolers obviously. The fan covers the entire heatsink. The heatpipes curves projects out a lot, which can cause some installation trouble if the heatpipes interfere with motherboard components.
Figure 6: Heatsink without fan.
The 92-mm fan has a classical frame, but the blades are white with an exclusive design. As you can see in Figure 7, its power connector is a four-pin miniature type, with PWM control pin, i.e., the motherboard controls the fan rotation speed.

Figure 8: Fan blades detail.The base is made of copper, with a very smooth finishing. In Figure 9, you can see a screw reflected on the base. You can also see how three heatpipes can look as five.
