Edit: TL;DR If you like a quiet/silent machine at idle - avoid the hybrid GPUs/kits because the pumps aren't designed for quiet idle operation. According to EVGA technical support there is no way to turn this pump down at idle, it is much louder than all other components combined at idle. The FTW3 triple fan HSF setup is silent at idle, all fans are off. The FTW3 Hybrid cooler fan is off when idle but the pump never stops. It is 100% all the time and just hums along. Took my silent idle PC to an annoying background noise at all times. The orientation of pump isn't making a difference. The location of the radiator/manipulating the hoses have no impact on the noise either. The pump is just relatively loud when the computer is idle. There is software from EVGA for CLC (closed loop coolers) but it doesn't include GPU CLCs just CPU CLCs as far as I can tell. When I loaded the software it stated there was no detected device. Unless you have limited hearing or have a really noisy environment, you won't like this pump at idle. Waste of money.

Did you Bleed any Air in the Pump out to the Top of the Radiator?

I'd say if you can hear the pump it must have air trapped in it. A pic of your rad placement please.. putting it right and give it some time for the air to settle in the rad would be key.. unless the pump is bad.

Rad higher thrn the card and with the lines at the bottom is key. If you have it that way run a benchmark or game with heavy load long enough for the pump to kick into high gear and tip the case so the water lines on the card are higher then the card so the air is flushed out to the rad.

There initially was air in the tubes but it cleared out quickly, the noise issue I'm having is just the default pump since it can't spin down.
I went down to the local shop where I bought it and they had one in one of their system's. Same noise, it is simply loud when idle (relatively). FTW3 is silent at idle, FTW3 Hybrid is very much not.

Wow. They've done a lot of db tests with hybrids and fans and the consensus was always that water was quieter, and you found 2 with same issue?

If you have a silent or 'fanless' build or something approaching that, the pump noise will be audible. As the OP points out, it will be relative. Someone running a half dozen case fans at 50%, it would be relatively *quiet. I don't know if the OP has considered this, but the pump might be causing a resonance with the case. Experimenting with some sound absorbing material might make a difference.
And there is also the other solution of running the pump off of a fan header on your motherboard. You control the speed that way using SpeedFan for example or just set it at 95%.

There is a cable extension you can buy that you attach the GPU pump header to, and then you can run it off one of the motherboard headers. Apparently setting it to less than 100% should help the noise. I will be trying it myself shortly. Cable for reference: https://www.amazon.com/JKtech-Pin-Mini-GPU-Adapter/dp/B0713P7X78/

My tower has absorption material in it already, along that same line thought I'm considering getting something to stuff in-between the pump and the shroud beyond the included pad in hopes of reducing noise. In regards to the resonance that was also an issue, I'm using a dead UPS as a paper weight to prevent it. Looking for a long term solution to that but that is separate from the pump's innate noise.

At load, definitely. The FTW3 with 3x fans at full load was like a blow dryer. Now it is much quieter at full load. But I don't have my computer at full load very often. More often than not the GPU is idle and every cooling device (fans) inside the computer are off or at a very low RPM that makes them inaudible. The Hybrid's pump at idle however is just as loud as it is at full load and takes my idle noise from borderline inaudible to distractingly noisy.

What case ? If the side panels are not perforated for venting - I would expect the "noise" to stay in the case I run two of those GPU, but almost never at idle I've bought scraps of self-sticking sound absorbing "rubber" mat from my local custom audio installer - when this case side had a resonance issue

I suffered with this for a year on my Corsair 780T. The cause was the RE3 Blacks, specifically one of them. I'd have to fiddle with the case a bit every day or so do dampen the low frequency hum. Finally replaced the drives...sweet blessed silence. For the Hybrid, after hearing about the possibility of buzzing, I put a 1" square 1/4 soft felt pad between the shroud and the pump cover when I first assembled it. Nary a peep so far but since I mounted the felt prior to testing, who knows.

I've got about 40 lbs of dynamat in my Ranger... about 1000 watt RMS Rockford-Fosgate...what what did you say??? I've probably got several square feet of it still around...I don't know why that didn't occur to me for damping vibrations in a PC case...thanks!

No HDDs in this PC so no vibration from those. The pump has a little pad on it already but I think I'm going to get another to see if it helps.

If you want silent - I feel your delima Mine are Folding HARD, case fans and all are Maxed -- all I hear is PPD, PPD......(points per day) Is the Top of your case Open ? that looks like an option for improved air flow and AIO rads I personally like background music to drown-out ambient noises

I considering doing this as well but I fear the long term effect it might have. Unless the pump is designed to run at different voltages (or whichever unit of power is relevant here) I fear it might damage it. I had a corsair CLC before and the pump made a racket unless it had full power from the header.
I am curious how it goes, I'd appreciate the follow up.
I did the change and you can definitely control the pump this way. I have it silent now. I am keeping a close eye on temps but everything seems fine.

What are the different percents you're running? I assume 100% and 0% work fine. You have it hooked up to a motherboard header, right?

That's right. I have a Gigabyte z270 board which seems kind of crappy in comparison to other boards for fan/pump control. But I played around and found the aquarium pump sound to be eliminated at around 70%. Going around 20% it starts making weird noises, and under that it basically shuts off. Temps under load were around 53-56C @70% (S340 elite has terrible airflow) which is about where it was before.

He got it in, works great. 0% turns it off and 50-70% still runs and does well for light gaming.

Glad to hear it worked out. Another neat trick you could consider; you can buy a similar cable (not the exact same) to plug into the unused fan header on the GPU, and run that to the radiator fans. This would allow you to control the fan speed via the Precision software. Only issue I've found is that the percentages don't match the fan RPM's really well. On my setup, setting the fan at 70% in Precision runs it at 100%. I'm not sure what that's about, probably a calibration thing.

It was working great for a while, but none of his motherboard headers detect the pump anymore. Pump still works fine but he can only set it to 100% now, shame since it's such a high vibration and noisy pump.

This is somewhat of a repost, but I'm posting it here to add to those that have mentioned the noise issue:
So I have a 1080 Ti FTW3 Hybrid. Since day one it has always been silent, even with half of my case fans turned off when temps are low enough. Today I added a fan and moved another fan to a different spot. I was extremely careful with the case and didn't drop or jolt anything on or near the 1080 ti. The settings were unchanged and the radiator fans are set up exactly as they were before I noticed the noise.
With the additional fans, I have a total of thirteen fans in my case, and even with all of them spinning, I still hear the pump hum over the top of all of them, with or without the case side panel shut or open. You can trace the vibration making the noise. I have systematically disabled fans, including the one I just put in, and it is not any of the fans making this noise. My hearing is most definitely NOT just suddenly better than it was yesterday or last week. This is a new hum, and you can straight up feel the vibration when you touch the card. It was NOT doing this before. I am afraid I'm going to have to RMA this card, much to my chagrin. I will give it a little time and wait and see if it's just pump break-in or something. I've had it for about two or three weeks, if memory serves... "Break in" was suggested by the EVGA tech I called. How long does this break in period last for these pumps?

My pump was really loud on my second boot but I shook my radiator and pump for a good 15 seconds to the point where I could hear the liquid being swished around and now it is almost completely silent. I think it helped my temperatures too as I've never idled at 24c before
