WaterCool MO-RA3 420 LT black

Our MO-RA3 (Monster Radiator) is considered the best solution for almost any application. It is not only perfectly suited for maximum silent systems. Also massively overclocked gaming systems can be easily cooled by this radiator. Even 24/7 operations of servers or workstations are no problem with this solution. It is even frequently used in industrial appliances, thanks to its powerful and robust design and construction.

Nothing beats surface

To cool big heat loads like that, you require big amounts of material. In one MO-RA3, we use over 36 meters (118 ft) of copper pipes, connected to more than 3 square meter (33 sq ft) of aluminum fins. The fin geometry is optimized for fans with low rotations per minute.
We organized the copper pipes in four parallel rows to minimize the flow restriction. The coolant flows through 80 parallel pipes which transfer the heat to the cooling fins. The massive overall surface guarantees high cooling performance!

User friendly and flexible

Our MO-RA3 is also very popular with beginner watercooling enthusiasts. External mounting doesn’t require specialized computer cases. Equipped with the dedicated feet (sold separately), you can place the MO-RA3 wherever it matches your setup. Even putting it on your walls is possible thanks to the wall mounting kit (sold separately). Combined with quick disconnect fittings, the whole system is mobile and flexible.
The port terminals are flow optimized, as well. They offer full flexibility with three G1/4’’ ports for inlet and outlet each. Several additional threads offer mounting positions for optional accessories like HEATKILLER® Tube adapters or fan grills.

Separate mounting kits for thicker fans are available. You can populate one side of a MO-RA3 LT with fans. You can choose freely which side you want to use. The preinstalled mounting brackets can be switched from one side to the other.
You can populate both sides of a MO-RA3 PRO with fans. The PRO version can host double the number of the fans than the LT version. A powerful push/pull configuration is also possible with the PRO models.
