Description

Turn your Corsair TITAN AIO into something more than just a cooler — make it a statement piece.
This snap-on mod adds a digital air freshener to your pump cap: inspired by the classic "Wunderbaum," now upgraded with a full-color screen, rotating images, real-time temperature, and brightness controls — all powered by a Raspberry Pi Pico.

Whether you're building a sim rig, love retro vibes, or just want something that makes your PC setup feel truly yours — this mod brings personality, motion, and a smile to your build.
