Gigabyte G-Power II Pro

For as long as I can remember, Gigabyte products have always stood out as being different. For the record, CPU coolers have a wide range of "different", as our collection for this article has proven. But the Gigabyte G-Power II Pro is a whole new animal, which doesn't happen all that often in this industry. So when I say they're different, I mean different as in the Segway or Good Year Blimp. The Gigabyte G-Power II Pro is unique in that it offers a viable cooling solution for enthusiasts and overclockers, but it goes about the delivery different than the rest by using a curved arc-shaped heatsink to help cool the system components at the same time as the processor.

While I can appreciate that Gigabyte is trying to cool two components instead of one, the G-Power II Pro doesn't have the most powerful fan integrated into it and should be paired with an exhausting case fan for best performance. Furthermore, the integrated fan will mean that hardcore overclockers will not be substituting the stock fan with another of their choice. Unfortunately, this also means that the G-Power II Pro is only going to receive stock fan testing for this article.


Gigabyte has designed the G-Power II Pro with five heat-pipe rods, which span into an aluminum heatsink base. The heat-pipes and base are both nickel-plated copper, which will add some uniformity to the overall appearance but also act as a barrier for escaping heat. The contact base of the GH-PSU23-PB is extremely smooth and flat, but it too is finished in nickel and thus reduces the thermal conductance between surfaces.

The Gigabyte G-Power II Pro uses a proprietary clip system for fastening the cooler onto the motherboard. Installation requires that the motherboard be removed from the case so that the screws can be fitted from the back. Once secured, the G-Power II Pro creates very good pressure between the contact surfaces.
