Where to plug in Corsair H70 on Gigabyte AORUS Gaming 7

[platonicpotato]

Question 1
Hi, soon i'll be building my new pc (my motherboard is a Gigabyte AORUS Gaming 7) but ive been wondering if i should plug in my Corsair H70 pump header to the CPU_FAN slot or the "CPU_OPT" header, which in the manual is defined as....
"CPU_OPT (Water Cooling CPU Fan Header)
The fan header is 4-pin and possesses a foolproof insertion design. Most fan headers possess a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation (the black connector wire is the ground wire). The speed control function requires the use of a fan with fan speed control design."

Or do I have to insert it somewhere different? i'm really not sure whats best to do. I want the pump to run at 100% all the time.

Question 2
When i finally have my rig built, i want to set up an XMP profile so that my memory would run at the advertised speed of 3200mhz. However, i have no clue how it works or what i have to do to make it run safely at 3200mhz. I've been told that all i have to do is set the XMP profile to profile 1 and i'm set, is that true?

Question 3
I want to run the fans i have hooked up to my radiator at 100% all the time also. What do I have to do in order to do that? where do I have to go in the BIOS to set the speeds?

Here is the rig im building

1| CPU_FAN. The fans of the cooler can attach to the daisy chain cable.

2| Get into BIOS, under the memory settings option, just enable X.M.P. Please make sure your BIOS is up to date as well.

3| You could go into BIOS and set CPU Fan speed to maximum instead of AUTO/or following a particular fan curve but for the sake of relevance it's best not to tamper with it at the moment and slowly learn how your new system handles.

1: plug the pump into the fan header directly underneath the 24pin ATX power connector, this is the header for the CPU fan/pump. This header ramps based off of the CPU package temperature meaning it will turn up if needed and down if not. if you plug into any of the other fan headers it will not ramp with the CPU and lead to worse cooling. Also locking it at 100% will drastically reduce the lifespan of your pump.

2: When you finish installing your OS and getting the basics set up restart and go into the BIOS. then go to Memory settings and select enable XMP. I don't know the specific tabs on this motherboard but GIGABYTE boards have very very intuitive BIOS setups so you shouldnt have a problem. simply change the setting to XMP then save and restart

3: Use the bottom right most fan header to plug in a splitter or single plug for your radiator fans this is another CPU fan header and will make them ramp properly. Again you not only do not need them at 100% all the time you don't want them at 100% as it will be loud and wear down your components far faster while giving absolutely no benefit to cooling.

Thenks for your answers guys. I have 1 more question. I will not be updating bios unless i encounter problems but when i have everything set up, which drivers do i download? i'm asking this question because in the drivers tab on the site that i'll link below, if i choose windows 8.1, which is the OS i'm running, it will not include CHIPSET drivers but it does if i choose windows 10. Does that mean i don't need chipset drivers if i have windows 8.1? I'll be using the SSD im using now which means i wont be reinstalling my OS or anything like that. I'll just be using what im using now.

You will need to update your BIOS to ensure compatibility and functionality in general so don't avoid it. After that the primary concern will be Video Drivers and then whatever windows tries to install
