The CNPS9900DF (Cont’d)
The rear of the cooler is shown in Figure 7. You can also see the fan connectors; the front fan has a three-pin connector, while the middle one has a four-pin connector. This means that only the middle fan is PWM-compatible.
Figure 8 illustrates the bottom of the cooler. Notice that one heatpipe goes to the front heatsink (with both tips inserted into the base), while two heatpipes are inside the rear heatsink.
Figure 9 shows the base of the cooler, perfectly mirrored.
