What customers say
Customers overwhelmingly praise the KBDfans module foam as an essential acoustic upgrade for compatible keyboards. The core theme is superior sound refinement. Reviewers consistently report that this foam dramatically reduces case resonance, eliminating unwanted hollowness for a deeper, more muted typing sound profile. Installation is exceptionally easy due to the precision pre-cut design, allowing the foam to drop seamlessly into place. This convenience, combined with the significant improvement in acoustics—often described as a satisfying thock—makes it an excellent value. For users within the KBDfans ecosystem, this small component delivers a disproportionately large enhancement to the overall typing experience, confirming its status as a high-quality, necessary addition.
Know before you buy
The kit includes a variety of 1, 3, and 4-hole foam pieces that you can place individually under specific switches. This allows you to customize the dampening profile based on your specific PCB layout and the keys you want to prioritize for sound refinement.
The foam is 3.5mm thick, which is standard for most mechanical keyboard builds. However, you should ensure there is enough clearance between your PCB and the bottom of the case to accommodate the foam without causing pressure or interference.
The 3M adhesive is designed for a secure, long-term hold once applied to the PCB. While it can be removed, doing so may leave residue or potentially damage the foam, so it is best to plan your placement carefully before sticking it down.
PORON is a high-performance urethane foam known for its excellent compression set resistance and vibration dampening properties. It effectively absorbs high-frequency noise and stabilizes the typing feel, resulting in a cleaner, more consistent sound profile.
No, the modular nature of this kit means you can use as many or as few pieces as you like. Many enthusiasts choose to apply foam only to specific areas, such as the spacebar or modifiers, to achieve a balanced sound signature.
