Watercool introduced huge MO-RA IV radiators for liquid cooling systems

The German company Watercool, specializing in the production of liquid cooling systems and their components, presented a series of MO-RA IV radiators. They are designed for custom LSS circuits for heavy-duty gaming PCs, workstations and server systems.

The new items will be produced in white and black versions. The series includes three models: MO-RA IV 200 with a volume of 0.81 l and weighing 6 kg, MO-RA IV 400 with a volume of 1.35 l and weighing 8.7 kg, and MO-RA IV 600 with a volume of 3.04 l and weighing 15.9 kg. The younger model is priced at $250, the middle one at $327, and the older one at $600.

All MO-RA IV radiators are 75mm thick and support 200mm fans. The MO-RA IV 200 supports the installation of two 200 mm fans, the MO-RA IV 400 supports up to four such fans, and the MO-RA IV 600 offers the installation of nine 200 mm spinners. In addition to the enormous cooling capacity, the new products have a modular design. This means they can be placed almost anywhere—attached to a computer case (you’ll need a very large case), placed free-standing on stands, or even hung on a wall.

The 200mm fan frames and grilles included with the radiators have a simple mounting system that does not require the use of screws. Each fan frame also features a cable management system, making the finished assembly look tidy without cables hanging around the heatsink. This will be especially true in the case of the MO-RA IV 600 model, which supports the installation of nine fans, each of which is equipped with its own cable.

All MO-RA IV models offer support for passive and active control. The passive control controller delegates the task of controlling the fans and pumps of the liquid cooling system to the motherboard. The controller for active control adds more functions, monitors the filling of the cooling circuit, reads digital temperature readings, and also signals if something in the cooling circuit is not working as expected. In addition, both types of controllers support ARGB lighting.

MO-RA IV radiators are not intended for use in conventional computer cases. It will probably be very difficult for them to find a commercially available consumer computer case of suitable size. Most likely, these heatsinks will be used in custom PC cases, large workstations, or server-grade PCs that can run 24/7, 365 days a year.
