Now before we dive into a big photo shoot, a quick overview and the manufacturer specifications. This is an all in one kit. Hybrid means you cool the GPU with the liquid cooling block and the fan cools the rest of the card like memory and VRM area.
The skinny from Arctic Cooling:
The Accelero Hybrid 7970 offers an air and liquid combined solution for the world's first 28nm GPUs, especially compatible with AMD 7900/7800 series. Different from traditional VGA Liquid Cooling Solutions (LCS) that are restricted to a specific graphics card, this cooler is compatible with a vast range of AMD graphics cards. If you are a computer enthusiast or gamer, you will definitely love its quiet operation and superior cooling performance on your graphics card.
It features the F12 (a 120 mm PWM fan), a powerful heat exchanger, and MX-4 thermal compound to transfer heat efficiently away from the GPU – with 200% cooling performance of the stock cooler.
Enhanced RAM and VR Cooling
It also comes with an Active Cooling Unit and thermal adhesive specifically designed to enhance the cooling of RAM and VR. Its aerodynamic design further maximizes the airflow efficiency on all surrounding components.
The PWM fans are both controlled by the graphics card and work according to the GPU load which minimizes the noise level. The PWM setting can be modified according to the different performance and noise priorities.

So the basic building block for what we'll do today is illustrated here. We'll first disassemble the reference cooler from our reference Radeon HD 7970, and then prep and fit the Hybrid cooler.
After we've assembled the kit we'll mount the graphics card into a PC. You can alternatively configure a couple of spots/placements for the radiator, as shown above. Whatever you prefer, the temperature of the R7970 GPU will go down dramatically as well as the noise levels. We'll show you that later on in the article.
We review the Arctic Accelero Hybrid 7970 Liquid Cooling System. A great performing Hybrid cooling solution.
Arctic Accelero Xtreme 2900 VGA cooler review
The Accelero Xtreme features with 5 heatpipes, 107 fins and 3 power managed fans. The design has been improved for optimized air flow design obviously to cool effectively, which according to Arctic is up to 240 Watt heat dissipation; that's quite a lot. They claim to can dramatically bring down the heat from GPU at least 20ºC lower than the stock cooler. Well .. let's slap a Radeon 2900 XT on it and see how well it does the job then.
