Phobya 120mm Radiator Gasket 38285

This Phobya gasket is a fine plastic foam seal cut for 120mm fans. It sits between the fan frame and a radiator or enclosure to close the gaps that let air bypass the cooling fins. One side carries self-adhesive tape for quick placement before the mounting screws are tightened.

For builders sealing 120mm fan mounts

The gasket suits anyone assembling a custom water-cooling loop who wants to stop airflow leakage at the fan-to-radiator interface. It will not help installations that use larger or smaller fan sizes, nor cases where the mounting surface is too uneven for the foam to compress fully.

Self-adhesive foam changes installation speed

The pre-cut shape and sticky backing remove the need to trim universal sheet material or apply separate glue. Compression down to under 1mm creates a tight seal once the screws are torqued, turning a small accessory into a measurable reduction in lost static pressure.

Questions about this item

What fan size must I already own for the 120mm gasket to fit?

The gasket is pre-cut for 120mm fans, so you need a 120mm fan to match the mounting holes and dimensions.

Will the 5mm thick gasket still seal if my radiator has older, slightly warped mounting flanges?

Yes, the fine plastic foam compresses below 1mm, letting it fill uneven gaps between the fan frame and older radiator surfaces.

How can I confirm the gasket is seated correctly after I stick it on and mount the fan?

With the fan screwed down, check that the grey foam is visibly compressed and no gaps remain around the perimeter; airflow should now pass only through the radiator fins.
