Aquaero USB 4.0 controller review

This device lets you control fans in reference with temperatures in control points, as well as it can be used to create supervision and control complex for watercooling systems (WCS), that can eve shut down PC in case of a system crash



Nowadays lots of cooling control and management devices are made. But not all of them are highly functional and can meet requirements of hard-to-please users. Among all of the controllers capable of not just fan controlling there are two most popular devices — Aqua Computer Aquaero and mCubed T-Balancer. To answer all questions needed to make the right choice, had sent me both controllers for testing. Because of their huge amount of available options I decided to make a review for each of the controller provided. And only then I′ll make a comparative review of those two. So let′s start with Aquaero review. This device lets you control fans in reference with temperatures in control points, as well as it can be used to create supervision and control complex for watercooling systems (WCS), that can eve shut down PC in case of a system crash.

This is what the manufacturer says about its product:

The name Aquaero was combined from the two words “aqua” and “aero”. Equivalently, the Aquaero is a device that is responsible for the connection of water and air. Although the main task of the Aquaero is controlling of fans used with a water-cooling systems it offers many further options. The Aquaero is absolutely autonomous working microprocessor-controlled device with USB-Fullspeed-connection. All speed parameters and sensor values can be set and visualized in a user friendly menu or through an even easier to use PC-software. Also it can show almost any information over the supplied jaLCDs. This includes the up-to-date whether, stock-market information, Heise-news, as well as information about PC


Aquaero looks like standard 5.25″ bay device:
