GRK Multi Fan Mount Ver.2 (Red Black Purple) [Shibata] R31S342BK R31S342RD R31S342PU

The DR Aluminum Cooling Fan Mount has received a minor update!
This new version supports cooling fans with a 24mm mounting hole pitch, including the SHIBATA DR Aluminum Cooling Fan and similar models.

While maintaining the core structure of the previous (R31S336) GRK Multi Fan Mount, the new design features an additional relief cut around the nut seat, allowing easier tightening using a socket wrench (*see note below).
This improvement significantly enhances workability and precision during angle adjustments and installation.

※ Depending on the socket’s shape or thickness, it may not fit perfectly in some cases.
