Hi,

I’m actually going to build my first PC.

ASUS Maximus VII Hero
I7-4790k
Corsair H110 for Cooling

My questions is about how to connect the Corsair H110 as well as the 2 Fan’s to be handled in PWM by the same Connection to the Motherboards CPU Header.

I bought already a specific Evercool ED-DF001 PWM Splitter cable and thought about connecting the Pump to the 4PIN PWM Connector and the 2 FAN’s, to 2 of the 4, 3 PIN connectors and all together connected to the CPU Connector on the Motherboard. The Idea is that the Pump Speed aswell as the Fans are increasing/decreasing there speed in relation with the CPU temperature.

When I look however to the 3 PIN connections of the Splitter, than I see that they have 2 pins, on free place and again 1 Pin. (1Pin ; 1Pin ; Free ; 1Pin)
This would mean that if I connect my 3 PIN fan’s (1Pin ; 1Pin ; 1Pin) to this connector, only 2 of the 3 PIN’s of the fan’s would get connected (Pin 1+2 or Pin 1+3, depending how they will be inserted).

I’m a bit confused and I hope that you can help me or give me some more information/advise to better setup the way the Computer will be cooled.

The Case is a Corsair Obsidian 750D that comes already with 3 140mm 3Pin Fans.
On top of these 3 Fan’s, I will have the 2 Fans of the Corsair H110 Water cooler and a Corsair Vengeance RAM Cooler.
The Motherboard has 6 Fan connectors and I thought connect them like this.

CPU1 (Water cooler+2Fan’s)
CPU2 (Corsair Vengeance Fan)
Case Fan 1 (Case Fan 1 from front)
Case Fan 2 (Case Fan 2 from Front)
Case Fan 3 (Case Fan from Back)
Case Fan 4 (reserve for an AF120 Fan on the bottom once the filters arrived)
 
Solution
You do NOT want to connect the pump to any header that will fluctuate voltage or pulse width (speed). The pump has to run at a constant speed at all times to avoid burning up and to provide best performance. The fans, however, can be connected to a controlled source if you want.. generally the CPU FAN header(s) if they are 4 pin. The rad fans will operate just like the air cooler fan would, speeding up with demand. But always keep the pump on a non-controlled +12V circuit. On my C60, I connected the pump to the PWR FAN header on my MB because that header is not controllable.
