Sounds like the transformer wining.  Shouldn't be making that noise.  I'd have Corsair swap it out.
 

LL140 and LL120? yes.
No, that's not possible. AFAIK.
All fans need to be the same series (all LL, all ML. all SP, etc.)

The reason I added the "AFAIK" is because the above thread only mention the RGB LED HUB:
Which is basically part of what the Node Core is.
 
Tagging @Corsair Nickto be sure.

Yes, you can mix LL120 and LL140 fans on one controller. Sorry for the ambiguity 😅
No you can't mix LL-series fans with another type of fan (like ML) on one controller (AFAIK).

I usually quote, then delete a bunch of stuff to only quote what I am directly responding to (selecting the text and pressing "quote selection" pop up works too for that).

@Nkw820 Go ahead and create a ticket on our support site like johnnyguru mentioned, and I'll work with our Technical Support team to bring in your PSU.  After you create the ticket, please PM me your ticket number so I can have it flagged for processing.  If you have any other questions about the process, let me know.

The CORSAIR H150i Elite Capellix would be a good option.  You can choose to turn off the RGB lighting, just set everything to black in the iCUE software.  It also comes with a 5 year warranty, should anything happen, we can have it replaced for you.  Let me know if you have any questions.

Your not doing anything wrong. There is only three option quiet, balanced, and extreme. You can only make custom fan curves but not pump speeds. 
 

Not nescecarily.

Looks like the SF PSU's 24-pin ATX, 8 pin EPS and PCIE cables match a couple other series, but the cables are shorter. Not sure about the other cables (SATA, Molex).

Thank you so much. Actually it's the metal cover of the top opening, not the filter itself (the 275q doesn't have a filter on top it's a metal that covers the top part for sound dampening i think). I glued all the magnets with a hot glue gun so it's ok now I don't need replacement. Thank you for listening this is actually better than getting replacement 😁

I'll pass the feedback along to our engineers to review.  If you need a replacement filter, we can have a replacement sent out.  You will just need to submit a ticket on our support site:

Try resetting the keyboard with the following method:
 
Unplug your keyboard. Hold down the FN and F4 keys and plug your keyboard back into your computer. Release the FN and F4 keys after 10 seconds. The keyboard should flash at this point. Open iCUE and update the firmware of your keyboard. Ignore any incompatibility warnings that pop up. If this doesn't work, you'll need to have the keyboard replaced through our RMA team.  You can PM me your ticket number and I'll follow up with them if they haven't already responded to you.

@Corsair NickMight be able to help you out with this. If he doesn't reply in a day or two, we can try and tag another Corsair member and try to have this issue resolved. 

Responded to your PM, and we should be able to get this sorted out.  After I get your response, I'll reach out to the senior members on our Support Team to get more details.

From what I've heard they have great customer service. They even have a guy in this forum @Corsair Nick for support I think so that's great

Again, I'm no watercooling guy, but I doubt you can fit that radiator configuration inside the case ;

@Corsair Nick Can OP fit the following configuration (custom loop) in the 1000D? Is it optimal ?
 
 

Why wouldn't you just contact Corsair? 
 
@Corsair Nick

Second this recommendation. 
 
If you are after looks then keep in mind that both iCue and CAM both relatively closed ecosystems - CAM Even more so IIRC. ICue does at least have some compatibility with Asus, plus there is more Corsair stuff to add than NZXT. Totally not relevant for performance whatsoever, but I wanted to mention it. 

Yup, we had about a 12 year gap where we didn't make them, but we're back at it.  We currently have the one model, CORSAIR A500, which launched at CES earlier this year.  It's compatible with all the latest sockets except TR4 and sTRX4.
 
 

Wow. i didnt know you made air coolers anymore.
 
I jut checked PcPartPicker, and there is like 3 Corsair air coolers.

Like others mentioned, very case by case basis, and what your habits are.  If you think it's one of those "too good of a deal to pass up" then it might not be a bad idea, but that's subjective to you.  You can gauge your memory usage in Task Manager for Windows to see how much you're using when you're doing your daily routine for work.
 
To give context, I have to use at least 32GB for my work PC since I have a ton of browser tabs, reports, and apps open all at once.  Personal PC, I run 16GB (ITX Build) since it really only gets used for gaming and web surfing.

Not entirely true about the pump depending on which CORSAIR cooler model the OP is looking at from our lineup.
Correct, we now support ASUS motherboard lighting control through CORSAIR iCUE.  Newer/current motherboards that support ArmoryCrate/Aura Sync should be all be supported in iCUE.  Older boards, it becomes a case by case.

Let's set the premise for some thermodynamics: cold air is more dense (more molecules) than hot air (less molecules).
 
Humidity makes the air less dense and creates for less friction.  For an air cooler, this is a bad scenario because there are fewer air molecules to create friction (transfer) the heat away from the fins.  Since Air Coolers are typically more reactive compared to water cooling by design, the reduced air molecule count will inhibit it's capacity.  AIO's and custom loops on the other hand can have a much larger capacity depending on radiator size. Larger radiators allow more time for the same water molecule traveling through the loop to cool, which in part allows for it to interact with more air molecules and transfer the heat before it hits the block again.
 
If you've ever had the pleasure of owning and driving an air cooled vehicle on a hot summer day, you'll understand this concept all too well.
