- Raijintek Morpheus II – Best for Enthusiasts and Overclockers
Design and Build Quality
The Raijintek Morpheus II creates a strong visual impact through its extensive heatsink structure. The cooling system uses an extensive heatsink system together with standard PC case fans instead of using small GPU fans which most stock coolers utilize.
Some of the key design elements include:
12 copper heat pipes
129 aluminum cooling fins
Mirror-polished copper base
Support for two 120mm fans
24 RAM heatsinks and one large VRM heatsink included
The cooler design delivers exceptional heat dissipation performance. The large heatsink extends its thermal distribution across multiple surfaces while the dual-fan system creates efficient airflow patterns.
The cooler lacks built-in fans because manufacturers designed it that way. The design appears strange to some people but it serves a deliberate function. Users can select their preferred 120mm fans based on their needs for quiet operation or strong airflow or visual design.
Cooling Performance
The Morpheus II achieves its best performance through its cooling capabilities.
The air-based GPU cooler provides impressive performance because it can handle approximately 360 watts of thermal output.
The testing results show that stock coolers and tested products have a major performance difference. The Morpheus II showed a temperature decrease from 77°C to about 57°C when installed on a graphics card during a demanding game test.
This kind of improvement can help:
Prevent GPU thermal throttling
Maintain higher boost clocks
Improve overall stability during long gaming sessions
The cooler system enables complete thermal management changes for older high-end cards such as the GTX 980 Ti and Radeon R9 290 which operate at high temperatures.
Noise Levels
The Raijintek Morpheus II provides users with its main advantage of reducing operational noise.
The system achieves its airflow capability through its ability to use two 120mm fans which operate at lower speeds across wider blade surfaces. The system produces lower noise levels because it uses larger fans compared to the traditional small high-RPM GPU fans.
The testing results demonstrate that the cooler maintains GPU temperatures between 60 and 70 degrees Celsius during heavy use when fan speeds are correctly adjusted, while the system operates at a silent level of sound which becomes nearly undetectable depending on which fans are selected.
This feature provides significant benefits to individuals who construct either silent or low-noise personal computers.
Installation Experience
Users need to demonstrate their ability to maintain focus because the Raijintek Morpheus II installation process requires work despite its easy completion.
The process usually includes:
The process starts with
The stock GPU cooler needs to be removed from
The GPU die needs to be cleaned after
The small heatsinks have to be attached to VRAM and VRM components before
The main heatsink needs to be mounted after
The installation requires two 120mm fans to be installed.
The cooler uses its extensive collection of small heatsinks and thermal adhesive pads to provide cooling solutions for memory chips and power delivery components.
The installation process becomes enjoyable for experienced PC builders who want to construct their systems through hands-on work.
Size and Compatibility
The primary aspect which warrants attention relates to the dimensions of the object.
The Morpheus II heatsink exists at dimensions of 254 × 98 × 44 mm, but its fan installation results in a three-to-four expansion slot requirement based on the installed fan thickness.
Before installing it, you should check:
Case clearance
Distance from the CPU cooler
