Watercool MO-RA IV Passive Control 200/400 (26081)

The MO-RA IV Passive Control Module is the ideal control unit for your MO-RA IV radiator. All the prerequisites have been created to achieve maximum performance even over long distances. This is achieved through an amplified and conditioned PWM and tacho signal for stable transmission.

The 5 volt rail provides 30 watts of power and the 12 volt rail provides 120 watts of power. This means that 2 D5 pumps, 18 fans and up to 3 aRGB modules can be operated without any problems.

MO-RA IV Link the rule and control interface

The connection from the PC to the MO-RA IV is established via the compact link module. The link module is mounted in the PC case and connected to the mainboard. The passive control module is installed on the back of the MO-RA IV radiator. A 1.5 meter long main connection cable then establishes communication between the mainboard or computer and the MO-RA IV unit.

The control and monitoring takes place with the software provided by the respective mainboard manufacturer. You can monitor a pump signal or a fan side on the radiator. The fan side can be selected via a toggle switch on the passive control module. Appropriate lighting has also been taken into account. Up to three aRGB modules can be connected and configured and adjusted via the mainboard software.

Comprehensive MO-RA IV Control Set

The MO-RA IV Control Module is delivered as a complete set. The set contains all components relevant for assembly. A special highlight is the hidden fan hub, which is installed on the underside of the radiator and enables hidden cabling. The same applies to the 1.5 meter long main connection cable, which is also optionally available in a 3 meter version.

Overall, only one cable, the main cable, is required for the entire control and monitoring.

The integrated 2-port USB hub (USB 2.0) enables the connection of e.g. USB-supported pumps or other USB devices.
