Design and Functionality

Once you have Akasa Revo in your hands, you will undoubtedly be surprised how little it weighs: only 300g! Of course, since the whole thing is made only of aluminum, even the cooler base has not a gram of copper in it:

The cooler design is more than original. There is a “plump” aluminum heat-spreader in the base with two pipes connecting it to the radiator:

The radiator is cooled with a 92-mm fan sitting in a plastic frame:

The frame and the fan can be easily removed letting us take a close look at the Akasa Revo design:

This cooling system works according to a very simple principle. The scheme below gives you a better idea of what it is:

So, the CPU heats up the liquid-coolant inside the circuit. Warm coolant then travels up to the fine-finned radiator with about 1200sq.cm cooling surface. It goes through the radiator fins, which are cooled by the airflow from the fan. After that the coolant travels down, back to the heat-spreader. It literally goes down, because Akasa Revo can be most efficient only if installed as shown on the picture above. Nevertheless, the manual suggests that the cooler may also be installed in one more way, although the highest efficiency in this case is not guaranteed:

According to the manufacturer, the coolant travels at pretty high speed within the circuit thanks to a special additive that makes the liquid bubble when hot. Of course, the chemical contents of the coolant is not disclosed anywhere.

As I have already mentioned above, the radiator is cooled with a 92 x 92 x 25mm fan supporting PWM rotation speed control:

The fan rotation speed may vary from 600RPM to 2200RPM generating 17-26dBA of noise and creating 11.44~41.96CFM airflow. The fan ball bearing is claimed to serve you well for 45,000 hours.

The aluminum cooler base is very even with a pretty ok finished surface:

Frankly speaking, we cannot explain why the manufacturer decided to give up copper base for Akasa Revo cooler, as copper is known to conduct heat much better than aluminum, which could have improved the cooling efficiency quite noticeably.
