3D-printed chimney cools Ryzen 7 9800X3D passively, drops temps 19°C
Modder der8auer built a 110cm 3D-printed chimney to passively cool a Ryzen 7 9800X3D, using the stack effect to replace fans. The mod reduced CPU temperatures by 19°C without any active cooling. This experiment demonstrates a radical, fanless approach to PC cooling that leverages natural convection.
Meridian48 take
While impressive, this DIY mod is unlikely to replace conventional cooling in mainstream PCs, but it highlights the potential for passive cooling in specific low-power or silent builds.
