Phobya 140mm rubber shroud for fan-radiator mounts

This 140mm rubber shroud sits between fan and radiator to improve airflow distribution across the fin surface and reduce vibration transfer. It suits builders assembling custom watercooling loops or upgrading air coolers who want quieter operation and better thermal efficiency from existing hardware. The 7mm thickness provides a firm seal that directs air through the fins rather than around them.

Vibration damping and airflow sealing at 7mm

Hard rubber construction decouples the fan from the radiator, preventing case resonance from fast-spinning fans. The material compresses slightly to close gaps between the fan frame and radiator, ensuring all airflow passes through the cooling fins. Stacking multiple shrouds with longer screws is possible for additional separation and sealing.

Sustained load behaviour

Under continuous load the shroud maintains consistent static pressure across the radiator surface, avoiding the dead-spot that forms behind the fan motor when mounted directly. Vibration isolation remains effective during prolonged high-speed operation, keeping structure-borne noise low while the radiator dissipates heat steadily.

Perguntas sobre este artigo

How do I fit the 7 mm rubber shroud between a 140 mm fan and radiator, and what step do people often miss?

Place the shroud flat between the fan and radiator, then use longer screws that pass through the fan, the 7 mm shroud, and into the radiator; the step often missed is sourcing screws long enough for the extra thickness.

Will the rubber material degrade or need replacing after a period of use?

The hard rubber is designed to stay elastic for the life of the cooling loop; no scheduled replacement is required unless physical damage or permanent compression occurs.

At what point does stacking multiple shrouds stop improving airflow efficiency?

Each added 7 mm shroud increases the air gap, so efficiency gains diminish once the gap exceeds the fan’s optimal static-pressure range; practical limits appear after two or three stacked units.
