Know before you buy
This radiator is specifically designed to accommodate 200mm x 200mm fans. The integrated tool-less mounting system is optimized for this size to ensure quick and secure installation.
Because this is a high-performance external radiator with a significant internal volume of approximately 0.81 liters, you should ensure your pump has enough head pressure to circulate coolant through the external loop effectively. Most standard D5 or DDC pumps are sufficient, provided they are part of a well-planned custom loop.
The unit features an integrated fan splitter that consolidates your fan connections into a single point. This eliminates the need for messy individual fan cables, allowing for a clean, streamlined look outside your PC chassis.
Yes, the MO-RA IV 200 features a modular design that supports optional passive or active extensions. This allows you to increase your total cooling surface area as your hardware requirements grow.
Absolutely. The MO-RA IV 200 is built with a solid brass terminal and has been pressure-tested up to 5 bar, making it exceptionally durable and reliable for high-pressure cooling environments.
The radiator utilizes a high-efficiency combination of copper pipes for the fluid path and aluminum fins for heat dissipation. The terminal is constructed from solid brass to ensure mechanical resilience and long-term stability.
