What radiators and fans can fit in the H7 (2026)? – NZXT Support Center

The H7 (2026) incudes support for the following fan and radiator configurations:

Location	Fans	Radiators
Top (requires steel mesh top panel)	Up to 3 x 120 mm fans Up to 3 x 140 mm fans	120 mm base, up to 360 mm 140 mm base, up to 420 mm ^[1] Maximum Combined Thickness: 61 mm
Front-right	Up to 3 x 140 mm	140 mm base, up to 420 mm Maximum Combined Thickness: 30 + 30 mm ^[2]
Bottom	Up to 3x 140 mm	No Official Compatibility
Rear	1 x 140 mm	140 mm

^{[1] - When using 140 mm radiators, ensure that memory modules and the top of edge of the motherboard do not exceed 52 mm. Taller heatsinks and memory modules may experience clearance issues.}

^{[2] - Radiators should be installed from the right-side of the case behind the Right Side Mesh Panel (part 11 in user's manual). Fans should be installed using long radiator screws included with the AIO liquid cooler from the main chamber of the case. Fans thicker than 30 mm may experience clearance issues with longer graphics cards or the angled fan mount bracket (part 17)}

Why is there no official compatibility for bottom radiators?

The bottom of the H7 cases includes inset 140 mm fan mounts which do not include clearance for end tanks on radiators. In addition, it is highly not recommended to use bottom-mount radiators with AIO liquid coolers as this could negatively impact the lifespan and performance of the cooler.
