This adapter cable allows you to connect 3-pin and 4-pin PWM PC fans to full 4-pin locking tab fan headers (most 4-pin fan headers feature a 3-pin locking tab)
Some 4-pin fan headers found most commonly in enterprise workstations and servers feature a full 4-pin locking tab which prevents physical compatibility with the majority of 4-pin PC fans which are designed for backwards compatibility with 3-pin fan headers
