280 mm radiator gasket for DIY liquid cooling

This black foam gasket fits a 280 mm dual radiator and uses 1 mm 3M performance foam with self-adhesive backing. It is designed for builders who want a low-profile seal between radiator and fans or case. The 15 mm hole spacing matches standard fan mounts. The gasket is supplied new and ready to apply.

Adhesive foam seal reduces vibration and air loss

The 3M foam layer dampens fan vibration and stops air from escaping around the radiator edges. This raises static pressure through the fins without adding bulk that could interfere with screw length. The single-sided adhesive keeps installation simple and the black finish stays discreet inside the loop.

Suits custom-loop builders sealing 280 mm radiators

Installers who need a thin, vibration-damping gasket for a 280 mm radiator will benefit. Builders using thicker radiators, different hole patterns or non-adhesive mounting should look at other sealing options.

Questions about this item

Will the adhesive backing on the 1mm foam gasket need to be replaced if I reinstall the fans?

The gasket uses a self-adhesive 3M foam backing; removing the fans will likely require a fresh strip of tape for a secure reseal.

At what point does the 15mm hole spacing limit compatibility with my 280mm radiator?

The gasket is cut for 15mm fan-hole centres, which matches the standard 280mm radiator mounting pattern; non-standard hole spacing would be the limiting factor.

Does the 1mm thickness add noticeable heat or noise once the system runs all day?

The thin foam layer is designed to reduce fan vibration and prevent air loss, so it lowers noise without adding measurable thermal resistance.
