Phobya 140mm Radiator Gasket

This grey gasket is cut for 140mm fans and sits between the fan frame and a radiator or enclosure. It is made from fine plastic foam with self-adhesive tape on one side for quick attachment. The seal closes the small gaps that let air bypass the radiator fins. Builders who want tighter airflow in a custom water-cooling loop will use it.

Sealing capacity and limits

The foam compresses to under 2mm when the mounting screws are tightened, filling the uneven surfaces between components. It stops the leakage that occurs when a fan frame does not sit perfectly flush. It cannot compensate for large misalignments or damaged mounting holes. Builders who need a thicker spacer or a rigid frame should look elsewhere.

Interface and practical constraints

The gasket matches the 140mm fan bolt pattern and is pre-cut to that spacing. It works with any radiator or panel that shares the same hole centres. It adds no electrical or thermal interface of its own. Builders using smaller or larger fan sizes cannot use this part.

Questions about this item

Will this 140mm gasket seal properly against my existing radiator's mounting holes?

The gasket is pre-cut for 140mm fans and uses self-adhesive tape for fixation, aligning with standard radiator mounting patterns to eliminate airflow leaks.

How can I verify the gasket is compressing correctly after I install the fan?

Tighten the mounting screws until the gasket compresses below its original 5mm height; the fan frame should sit flush with no visible gaps around the perimeter.

Does the package include mounting screws or only the grey foam gasket?

Only the self-adhesive grey foam gasket (part 38336) is supplied; fan or radiator mounting screws must be sourced separately.
