Modder uses 110cm chimney to passively cool CPU, cuts temps by 19C

A PC modder known as der8auer has successfully demonstrated a novel cooling method for CPUs using a 110cm 3D-printed chimney. This setup leverages the 'stack effect,' a phenomenon where temperature differences create natural convection, to passively draw air through the system. In testing with an AMD Ryzen 7 9800X3D, this fanless approach reduced CPU temperatures by 19 degrees Celsius, showcasing a radical alternative to traditional fan-based cooling. AI

    Modder der8auer builds 110cm 3D-printed chimney to passively cool Ryzen 7 9800X3D without fans, cuts temps by 19C without fans — radically simple PC mod cuts uses the 'stack effect'

    What if instead of relying on mechanical pressure generated by fans, you could just passively cool your PC using natural convection? That's what der8auer managed to pull off in his new experiment using the stack effect that targets a similar pressure differential but achieves it …
