Connect 2 PWM fans to your mainboards CPU socket.
Type PWM Fan Power Cables
Features
Connect 2 PWM fans to your mainboard’s CPU socket. Use
multiple Y cables to connect a series of up to 5 PWM fans and provide as
much extra cooling as desired.
Power drawn into your CPU cooler
is adjusted depending on its temperature. An idle CPU does not generate
as much heat, requires less active cooling, and hence slower fan speeds
will be sufficient. Further this also reduces the overall ambient noise
of your PC and it's handled automatically with little risk to your PC
components.
While PWM fan controllers are very common in today’s
PC industry and available on most mainboards, there is often only one or
two such PWM headers, reserved for the CPU and or the chipset fans.
The long cable provide enough length to reach any location in your case.
Cable Length: 12 inch
Connector: 1x 4 pin
Connector: 1x 3 pin
Plug: 1x 4 pin
*There
is suppose to be one pin missing on the second connector, motherboard
ports can only read one RPM signal so on splitters only one of the ends
has the RPM signal wire.
