Review on 4-Pin PWM Fan Power Supply Cable 1 to 5 Splitter Hub for ATX Computer Case, Internal Motherboard Fan Extension, 5 Way Splitter Cord Wire for 4-Pin and 3-Pin Cooling Fans, 13 inch, Black by Adam Hardy

Failed to use. After installing this and plugging in a standard case fan and then a new fan that I bought, I got system error 90b on reboot. By elimination I traced it back to this splinter. Also note that the new fan ran at full (loud) speed on startup when connected to the splitter. On the other hand, when I connect a new fan directly to the motherboard, it runs slower and much quieter at startup without any system error. So I had to deactivate this product and cannot use it.
