The Lian Li GA II 360 in a NZXT H9 is a common SA build pairing, and the DDR5 clearance question has a clean answer once you check height and thickness rather than eyeballing photos. The NZXT H9 is a dual-chamber showcase case with wide GPU clearance and solid radiator support.

Quick Answer

Yes. The Lian Li GA II 360 clears DDR5 RAM in a NZXT H9 in nearly every build, because the radiator and fans mount in the roof and sit above the memory, not across it. The only thing to confirm is that your roof has room for the radiator plus fan thickness, typically 27mm plus 25mm. Standard and most tall DDR5 kits fit without trouble.

What actually limits Lian Li GA II 360 RAM clearance

AIOs make this easy because the cold plate and pump sit on the CPU while the radiator lives in the roof or front. a 360mm AIO with a compact pump and standard radiator. So your DDR5 height is rarely the issue; the radiator-plus-fan stack thickness against the case roof is. In a NZXT H9, confirm the roof clearance figure covers a 27mm radiator plus 25mm fans, about 52-58mm total. Tall RGB DDR5 fits comfortably under a roof-mounted AIO.

Roof and airflow notes for the NZXT H9

The NZXT H9 matters as much as the cooler. a dual-chamber showcase case with wide GPU clearance and solid radiator support. For a quiet SA-summer build, mount the radiator in the roof as intake or top exhaust depending on your front airflow, and leave a slot of breathing room above the DIMMs. A typical pairing here is a 32GB DDR5 kit and a 750W or higher PSU, and good case airflow also keeps a 6000MT/s kit stable during long gaming or rendering sessions.

FAQ

Will the Lian Li GA II 360 fit DDR5 RAM in a NZXT H9?

Yes. The radiator and fans mount in the roof above the memory, so DDR5 height almost never conflicts. Just confirm the case roof clears the 27mm radiator plus 25mm fan stack.

Can I use tall RGB DDR5 with this AIO?

Yes. Because the radiator sits over the CPU socket area rather than across the DIMM slots, even tall RGB kits clear comfortably in a NZXT H9.

What roof clearance does the NZXT H9 need for this cooler?

Allow roughly 52-58mm of roof space for the radiator and fans together. The NZXT H9 provides this in its standard layout, leaving the DIMM area open.

TIP

doubt, choose low-profile DDR5. It removes clearance worry entirely and costs little performance on a tuned 6000MT s kit.
