Watercool launches massive “MO-RA IV” PC cooling radiators, featuring up to 9 fans and 120 81m-long pipes

Watercool has announced the launch of the MO-RA IV radiator series, a line of high-performance radiators designed for overclocked systems, workstations, and servers. The Germany-based company claims that the MO-RA IV's design is perfect for customization and generating raw cooling power. There are three variants for the radiators listed on the website with prices starting from €229.95, and they're dubbed 200, 400 and 600.

The MO-RA IV features optimized corrugated fins for improved airflow across various fan speeds and increased structural integrity. The radiators utilize a large surface area, with the MO-RA IV 200 model offering 1.7 square meters of aluminum for heat dissipation. That goes up to 3.2 sq. meters for the MO-RA 400 and 7.1 sq. meters for the flagship 600 version. 

The MO-RA IV has a modular design, allowing for various configurations. Users can use the optional stands for floor placement or wall mount the radiator using the bracket (sold separately). The system is further expandable with the MO-RA TANK, a flow-optimized reservoir that can be integrated with pumps to create a complete external cooling station.

The MO-RA IV incorporates several user-friendly features. The redesigned fan frame utilizes a screw-free Quick Mount system for easy installation, while the fan grille features a click-in mechanism for a secure fit. The radiator has both passive and active control options through purchasable extensions. The passive control module allows for basic regulation via the motherboard, while the active control extension, powered by a microcontroller, offers more advanced features like alarm functions, liquid level monitoring, and digital temperature sensor readings. Both control options are compatible with aRGB customization for lighting.

The MO-RA IV is constructed with copper tubes and aluminum fins, encased in powder-coated steel. The thing weighs approximately 6 kg (for MO-RA IV 200). The radiator is pressure tested to 5 bar and comes in black or white finishes. It includes mounting screws for fan installation and a fan frame with an integrated splitter. 

On the company website, the MO-RA IV 200 Black/White is listed for €229.95, while the MO-RA IV 400 Black/White has a €299.95 price tag. The MO-RA IV 600 with 9 fans and 120 pipes costs €549.95. The radiator is expected to be available from 19th August, 2024. It's still possible to pre-order them via Watercool's website.
