    • A 3-Pin fan to 4-pin IDE (Molex) power adapter is to power a computer case fan directly from the power supply unit (PSU) rather than thru the mother board.
    • Because the fan is powered directly by the power supply and not the motherboard,  the mother board has no electrical connection to the fan to 'see' if it is spinning.
    • If this adapter is connected to CPU Fan, the BIOS assumes the fan has failed and shows 'CPU Fan Error' during the POST (Power-On Self-Test). Change the 'CPU Fan Speed' setting to 'Ignore' under BIOS will tell the motherboard to stop looking for a signal from the fan.
    • Connecting the 3-pin sensor wire to the mother board will let the computer to 'see' if the fan is spinning.
    • Most 3-pin computer cooling fans share a standardized pinout specified by Intel and AMD allowing them to be interchangeable across most motherboards. However, some proprietary systems use different pin layouts that can damage components.
    • Check the polarity of the connection before use. Seller will not be held responsible for any damage to systems, parts, software used in conjunction with, data lost, corrupted resulting from the use of its products, or any other damages caused by the purchased items
