Reversing the Flow Direction

Magnitude 115x, 1700, and 20XX Water Blocks can be assembled in multiple orientations to achieve the same thermal and hydraulic performance when flow direction or branding needs to be reversed. For AM4 versions, rotating the Insert relative to the CPU socket is not recommended due to its asymmetrical design. The following orientations deliver optimal performance.

Diagrams show various IN/OUT port configurations for the water block, illustrating different assembly orientations.

Note: To prevent incorrect assemblies, the screw hole pattern is not square. The Top, Frame, Insert, Jet Plate, and Coldplate can only be rotated by 180°; otherwise, screws cannot be installed. The Accent, O-Ring, and LED Strip can be installed in any orientation. The Insert can be rotated by following the steps below.
