Ever since SilverStone entered the realm of rackmount server cases with radiator compatibility, the company has consistently sought ways to improve cooling performance. Its predecessor, the RM51, boasted 2 x 180mm fans, which provided exceptional intake performance. This innovative design allowed for the incorporation of a 360mm radiator (dual 180mm) and even featured an adapter bracket that facilitated the use of a 360mm radiator (triple 120mm). However, the successor, the RM52, maintains the same 5U form factor and internal structure, ensuring compatibility remains intact. Nevertheless, it stands out from its predecessor due to a significant upgrade. SilverStone's pursuit of enhanced cooling performance led to the inclusion of an additional 360mm fan / radiator bracket in the RM52. This groundbreaking innovation now enables users to utilize not just one, but two 360mm radiators to perfectly serve systems with dual CPUs.
