HI all,
I have just built a new Skylake system based on an Asus z170-A motherboard. I have a Fractal Designs Kelvin T12 water cooler mounted on the rear of the case (a Fractal Designs Define R5 with two front mounted 140mm fans connected to a fan controller on the case which takes power from a sata cable).
The 140mm case fans could be connected to the motherboard so that they can be controlled by software, or I could leave them connected to the case controller which uses a switch to adjust the power (3 settings - slow, medium, fast).
The water cooler has two 120mm fans, one each side of the radiator. both set up to push air out the back of the case.
The Kelvin T12 is supplied with a Y-cable so that both radiator fans can be connected to a single fan header.
At the moment I have the system set up with the water pump connected to a dedicated water pump header on the motherboard and I am using the y-cable to connect the two fans to the main CPU_FAN header.
However, that motherboard has two CPU fan headers available - CPU_FAN and CPU_OPT.
My queries:
1 Are there any drawbacks to having two fans connected to the single CPU_FAN header (i.e. could two fans overload it?).
2 What advantages are there (if any) for making use of the CPU_OPT header.
3 If it were your system would you leave the case fans connected to the case controller (manual control via a switch on the case) or connect them to the motherboard for automated software control?
Thanks all!
