Gigabyte is unusual among Taiwanese motherboard companies in that they don't actually do any OEM business at all, or so I was told by a key marketing person during the Computex computer trade show in Taipei last June. If this is true, it means that they rely solely on the retail market, which is naturally dominated by DIY enthusiasts, who are probably as fickle as any group of consumers. Perhaps as a response to this dependence, Gigabyte has diversified their range tremendously in the last few years, and it now rivals some of the biggest brands in the business.

Gigabyte's thermal solutions range takes up a major subsection on their global website, and includes many cases, air and water cooling products for both VGA and CPU, notebook coolers, and power supplies. The G-Power 2 Pro is the second CPU cooler from Gigabyte to be introduced to our torture chamber.

Our G-Power 2 Pro sample came in a huge retail box with full color graphics that promised a cache of eco-unfriendly packaging materials. The promise was fulfilled.

Big box, full of plastics and....

...a big closed-cell foam throne for the heatsink.
All the mounting hardware was in the plastic bag on the right.

The G-Power 2 Pro is another odd-angled heatpipe-based design, like the Volar we examined a few weeks ago. It's considerably bigger, however, and has many other differences. Judging by its position on the Gigabyte Air Cooling Solutions web page, the GP2P is their top model currently.

Feature & Brief Our Comment
Convex curves widen air range for both
CPU and MOSFET cooling
12cm high air bandwidth silent fan for heat dissipation 12cm fans are not unusual in high end coolers these days.
Pure copper-base, nickel-coated for durability OK, but pretty routine for high end coolers.
Back-end blue atmospheric LEDs We'd prefer none, but that's SPCR.
Heat pipe array comprising of 8mm thick heat piping They do seem thicker than usual, and this should help with heat transfer.
Fan speed adjustment by voltage bridging cable A variant of the 5V - 12V splitter with 3-pin fan outputs first offered by Zalman years ago.
