Hello everyone.
Can this water cooling system from Asus CPC ACC ROG RYUJIN III 360 ARGB EXTREME be mounted on an LGA 2066 socket? Many thanks in advance for your help...
No, the ASUS ROG Ryujin III 360 ARGB Extreme is not officially compatible with socket LGA 2066. This information is confirmed by both ASUS documentation and the community.
Possible alternatives
Opt for a motherboard using LGA 1700 sockets (more recent such as Alder Lake, Raptor Lake), if you absolutely must use this Ryujin III cooler.
Choose another AIO cooler with LGA 2066 support, like the old Ryujin 360 or other models (e.g. those explicitly mentioning this socket).
If you want to adapt, some users mention the possibility of manually adjusting the mounting (screws, washers, mechanical compatibility, etc.), but this is not recommended without official instructions.
