Compatibility and use

Officially compatible with all NH-L9i and NH-L9a variants, bridging a 5–45 mm gap between a 37 mm NH-L9 cooler and a perforated side or top panel. TK Lab also tested a single 10 mm layer in S5M006.

Construction and materials

Modular EVA foam spacers: 10 mm ×2, 7, 6, 5, 4, and 3 mm, combinable from 5 to 45 mm in 1 mm increments. Includes 16 plastic tubes and four steel bolts.

Installation

Stack spacers to the measured fan-to-panel gap, then locate them with the supplied bolts and trimmed plastic tubes. S5M006 uses a 10 mm effective height.
