PC Fan Extension Cable - PC Fan Extension Cable: Connect a computer case fan to a motherboard fan header using a 4-pin male to female connector for flexible placement. - Wide compatibility: Compatible with both 4-pin PWM and 3-pin fans, providing versatile use across fan types. - 30 cm extension: Extends the reach to simplify cable routing and improve overall cable management inside the case. - Stylish protective black sleeve: Fitted with a strong protective black sleeve for added durability and a clean, professional appearance. Practical use scenarios - Reaching distant headers in compact or complex builds: Use this extension when the motherboard fan header is located far from the case fan to avoid tension and keep cables tidy. - Expanding cooling in front, top, or rear positions: Install additional fans in various case locations without stressing existing cables, while remaining compatible with both PWM and 3-pin fans. - Replacing or upgrading short, damaged, or cluttered cables: The 30 cm length provides extra slack for neat routing behind the motherboard tray or along the case interior.
