This is a Python library and web service for accessing Aquaero fan controllers by Aqua Computer GmbH & Co. KG.

pyquaero is a community open source project. It is not endorsed by or affiliated with Aqua Computer.

NOTE: At the moment, pyquaero only supports Aquaero 5 and 6 with the now outdated firmware version 1036. Later firmware versions may work, but are untested.


The pyquaero main developer is running this software for several years now, without any negative side effects. However, it is a highly experimental software, and it is based on reverse engineering only.

  • This software might damage your Aquaero device in a way that it must be repaired or replaced.
  • The use of this software could lead to failure of cooling fans or aqua pumps, which might cause permanent damage to heat sensitive components of your computer.
  • Using this software might void your warranty.

Neither the pyquaero developers nor Aqua Computer can be held liable for any damage caused by this software. We strongly recommend to use only the official software!


pip install pyquaero

USB Setup

Accessing the USB port might need root permission. However it is not recommended to use pyquaero with root rights. Depending on the operating system, some extra steps might be necessary to give users permission to access the USB port.

Fedora, RedHat, CentOS

Execute this sequence to set up an aquaero group, change the Aquaero USB permissions and add the user $user to this group:

cat > /etc/udev/rules.d/40-aquaero.rules << __EOF__
groupadd -r aquaero
usermod -aG aquaero $user

The $user is now allowed to access the Aquaero USB device.

Later Firmwares

pyquaero only supports the now outdated firmware version 1036.

The reason is that I, as the developer of pyquaero, only own a single Aquaero, which is actually in use.

As there is no official documentation, pyquaero bases on reverse engineering of the data transferred via USB. Updating the firmware of my Aquaero could mean that pyquaero stops working, and I could be unable to make it work again. As I need my Aquaero, I cannot afford to risk that. For that reason, pyquaero is stuck to firmware version 1036.

If you need support of the latest firmware, I would be happy about a donation so I can buy a second Aquaero for experiments only. However I cannot guarantee that there will be a release that supports the latest firmware, if technical reasons prevent it.
