Enermax AquaFusion 240 Review: A Colourful All-in-One-Cooler

The Installation

The assembly of the AquaFusion was somewhat problematic. But one after the other.

The included SquA RGB fans can be easily attached to the radiator. Due to a light rubber coating, scratches and vibrations during operation can be avoided.

After the installation of the radiator with the mounted fans we continued with the compact CPU block. In our case two holders for Intel systems were already mounted in advance, which could easily be removed. Now comes the difficult part: the backplate of the cooler. According to the instructions it is not secured properly before screwing on the CPU block. The result is that the backplate can slip or fly out. As a simple solution, the case must ideally lie completely on the backplate – accessible by a book or similar between it and the floor.

After the successful assembly, all components are firmly and securely seated in the intended place.


With the SquA RGB fans and the illuminated CPU block, the AquaFusion provides comprehensive RGB lighting.

The lighting of the CPU block is particularly noteworthy: the 3D layer design is revealed here.

Especially in combination with the case Enermax StarryFort SF30 you get a very cool look. All LED elements of the case and the cooler can be controlled together via the LED controller of the case.

If the AiO water cooling is not to be used with the housing, the LEDs are controlled via the supplied switch. Various colour effects are also available here. In addition, a colour can be permanently displayed or completely deactivated.

Cooling Capacity and Volume

Let’s get to one of the most important parts: How does the AquaFusion 240 perform in practice? It competes against the Alphacool Eisbaer LT240, which uses alternative fans.

We test both cooling systems with 500 and 900 RPM. In addition the Enermax is operated with maximum RPM. Since the pump makes quiet noises at both AiO’s at full voltage, the voltage was reduced to 7 V by an adapter. To simulate the temperature under full load, Prime95 was used.

The room temperature for each test was approx. 24 ° C. At maximum speed, the cooling performance is impressive, but so is the volume. At 900 RPM the volume decreases significantly and should be quiet enough for most people. Compared to the Alphacool cooler, the cooling performance is at almost the same level.

At 500 RPM, the AquaFusion fans are barely audible. Compared to the Alphacool, however, the cooling performance is clearly worse.

In summary, it can be said that the cooling performance of the Enermax AiO is very good, unless the fans turn too slowly. Here the cooling performance decreases strongly compared to the competition. The sweet spot of cooling and volume should be between 700 and 1000 RPM, depending on the user.
