Note how greatly they had to bend the heat-pipes at the cooler base to end up with the shape like that:

And this is what it looks like at the other side of the base:

Why didn’t they make the central heat-pipe 8mm in diameter too? I can’t answer this question. Only the cooler designers can, but it is most likely resulting from their intention to avoid making the cooler base any bigger. Although I believe that additional 2mm will hardly increase the cooler base size that dramatically, while an 8mm central heat-pipe instead of the 6mm one would have had a great positive effect on the efficiency of the new Gigabyte G-Power II Pro cooler. Nevertheless, it is up to the engineers to decide. Here I would only like to add that each heat-pipe sits in the corresponding groove in the cooler base. This way they ensured bigger contact area between the heatpipes and the cooler base. The plate on top of them is made of aluminum and serves as support surface for different cooler retentions.

The cooler base, just like the one of the recently reviewed Gigabyte Volar is covered with protective paper sticker warming you that it needs to be removed before installation:

However, the base finish quality is ideal unlike the just mentioned Volar solution:

Mirror-shine polish of the copper base and its impeccably even surface checked with the thermal grease imprint on the glass surface can be a great example to follow even for such leaders of the cooling solutions market as Thermalright.

The fan sitting in a plastic casing uses a slide bearing (EBR) with 30,000 hours mean time before failure (about 3.5 years). The fan is 120 x 120 x 25mm big:

Nine aggressively bent fan blades rotate at ~700 or ~1,500 RPM. The fan rotation speed adjustment is performed via the corresponding 5V and 12V connectors:

The manufacturer claims that this cooler generates 16 and 23 dBA of noise respectively. Moreover, the fan features three blue LEDs looking very good for modding fans and some mainstream users who are not yet tires of Christmas lights and fireworks :) The faster the fan rotates, the brighter light up the diodes.
