Would a fan hub will work in Dell Vostro 3888? Does it will fry the motherboard?
Hi I recently bought a second fan here and I want to upgrade the fan to, but since the Vostro 3888 only has 1 fan header and I need a hub, and I wonder the hub will fry my motherboard or not. So that's my question. Would it work? Or it just fry the motherboard and throw an blinking lights?

Dell uses proprietor fans pinout on various systems. Therefore, taping into the fan headers could trigger system error or worse, fried the motherboard.
If your system has a standard fan pinout, you can use a fan splitter cable for the new PWM fan. If the pinout is undetermined or unsure, just power the new fan with SATA power cable and it will operate at constant speed.
If the CPU fan in your system is designed to draw air from within the system and exhausting out toward the rear of the case, your new intake fan can run at constant speed to draw fresh air from the front.

If you are talking about the CPU fan header, it may throw error codes. You can try to power the second fan with unused SATA power cable.

It just throw "CPU 0 Fan Failure" error instead or something? And the hub requires 4 pin pwm (for receive signal from motherboard) and sata port (for power). So do i need to connect both of them or just sata power?

@Chino de Oro Since the pinout is undetermined and there's no information in the instruction manual, I'll go with SATA power cable. Thanks for the answer!
