120 mm Radiator Gasket

This Phobya gasket fits 120 mm fans and sits between the fan frame and a radiator or enclosure. The fine plastic foam compresses from 10 mm down to less than 4 mm under mounting pressure, sealing the small gaps that let air bypass the radiator. Part number 38335 identifies the grey version supplied new.

Self-adhesive mounting

One face carries a self-adhesive strip so the gasket can be fixed to the radiator or chassis before the fan is screwed down. The foam then fills the uneven joint between the two surfaces, reducing turbulent leakage and letting the fan push more air through the fins. No tools beyond the standard fan screws are required.

Pre-cut fit for 120 mm fans

The gasket arrives already cut to the 120 mm bolt pattern, so alignment is immediate and no trimming is needed. By eliminating bypass airflow the accessory raises the effective static pressure across the radiator, improving loop temperatures without changing fans or pump speed.

Does the 38335 gasket include adhesive for mounting?
