Corsair H115i Question from a noobie

Hi guys, I recently purchased a Corsair H115i liquid cooler for my Intel 7700K. I have the following questions which are really bothering me before I even attempt to start building my PC. Please shed some light, thanks!!

 

1. The manual didn't mention how to plug in the SATA cable that comes out of the pump. Should I plug it in? If yes, does it go to my mother board or does it go to my PSU?

 

2. There are two fan connectors coming out of the pump. One of them has 4 pins, the other one has 3 pins. What is their difference? Does it matter which fan connects to which? I want to understand the technical difference : )

3. The manual mentions two kind of very similar standoffs, the LGA 115x /1366 Standoff and the AMD BLACK STANDOFF. Please see the picture below. I am going with LGA 1151, should I choose the standoffs above? Besides color difference, the black ones (I'm assuming they are for AMD) have different threads on each side.

Please comment if you know the answers! Thanks a lot!!!!!!

1. Yes, plug it into the PSU and connect the single wire to the CPU_FAN header. The H115i manual is incorrect, see http://forum.corsair.com/forums/showthread.php?p=901674.
   
2. Only one of the fan speeds is reported and that is the fan connected to the header with 4 pins.
   
3. I am not really sure which is which, but you need to use the LGA 115x ones.

Thank you for your fast response, red-ray!

 

Regarding No.2, if only one of the fan speeds is reported, does that mean I am able to only control the speed of one fan? or are they somehow synchronized at the same speed always?

 

Again, thanks for your help!

The fan speed is controlled by the PWM signal that goes to pin-4 so both fans should run at the same speed, see https://en.wikipedia.org/wiki/Computer_fan_control
