So if you want to cool a large number of components or are planning very ambitious OC experiments, the Mo-Ra is an adequate, top-class heat exchanger.
The manufacturer Watercool now offers the radiator in its third revision, which has been improved again. There are various models to choose from, which differ according to the features (LC/LT/PRO), the usable fans (120/140/180 mm) and the color or material (black/white/stainless steel). The Mo-Ra3 therefore offers a wide range to find your individual dream model.
This is still a radiator for external use, which is mounted directly on the housing or is free-standing. Internal installation is normally impossible due to the enormous dimensions. However, the enormous use of materials is also the main reason for the extreme cooling performance, as an equally extreme surface is available to release heat.
Overall, the Mo-Ra3 offers an incredible fin surface through which copper pipe flows four times in parallel in 72 rows of pipes. The fin geometry has been optimized for use with slowly rotating fans, so the Mo-Ra3 is recommended for silent use. The integration into the water circuit takes place via a total of six G1/4 inch threads.
This is the black version of the 420 LT. The slats here are unpainted, which goes very well with the black steel of the housing. The radiator is designed for use with 140 mm fans, nine of which are mounted in a three-by-three arrangement. The LT model differs from the cheaper variants in that it has an upgraded housing with stainless steel applications and fan mounting material for one side. This means that a total of nine fans with a height of 25 mm can be installed and - if necessary, despite the low speed - ensure extreme airflow.
In addition to the radiator, the scope of delivery includes 36 fan screws, spacers for mounting on the housing, four sealing plugs to seal the openings that are not required and installation instructions. The Mo-Ra3 is manufactured in Europe and largely in Germany itself.
