【Great PC Case Accessory for 3D Printing】Self-developed PC case fan riser block, raises the airflow path to reduce wind shear noise and increase air intake. Now available on MakerWorld! Please like and collect it, thanks for your support 🙏
A modified spacer block📌 specifically designed for desktop PC case cooling fans, to increase the distance between the fan and the case metal panel, eliminating airflow wind shear whistling and intake vortex issues caused by fans being too close to the side panel.
✅🔇Greatly suppresses wind shear noise: Features an independent air intake cavity to disperse edge turbulence, significantly reducing fan noise at the same speed, a must-have for silent PC case modifications.
✅💯Enhanced ventilation efficiency: Widening the negative pressure intake space, reducing intake resistance, effectively increasing fan CFM airflow, allowing hot exhaust air to be expelled faster from the case, resulting in better CPU / GPU cooling.
✅🔩Standard hole pitch compatibility: Compatible with standard 120mm PC case fan screw holes, with precisely drilled holes for direct installation without grinding, ensuring a secure and resonance-free assembly.
✅🖨️3D printing friendly: No overhangs, no supports needed, easily printable with both PLA/PETG, with high tolerance for wall thickness and infill parameters.
✅📏Multi-height specifications: 25mm riser height, can be scaled and combined as needed for various PC case airflow solutions.
✅🔇Circular arc inner wall guiding: Internal rounded airflow channels eliminate right-angle dead-end turbulence, smoothening the intake airflow, reducing wind shear noise caused by airflow tearing at the source, significantly lowering noise at the same speed.
Applicable for: Separate liquid cooling intake, front intake cramped PC cases, silent PCs, high-density multi-fan build modifications🛠️
