Mine sounds like that:
 
That's because these pumps run full speed, EVGA should build into their software a pump control app.
 
I am half tempted to unplug the pump from my video card and hook it to one of my fan headers on the mobo and see how that works
 
 
 

How do I troubleshoot Hybrid or CLC Pump Noise?  FAQ ID # 59719
 
(excerpt)
 
Answer / SolutionSometimes there are instances where a liquid cooler can make a gurgling or other unusual sounds. This is typically caused by air stuck in the cooler that needs to be circulated through the built-in traps on the radiator. Any air bubbles tend to go away quickly on their own as the coolant flows through the cooler. In some cases, it may be necessary to physically manipulate the radiator to free any stubborn air bubbles.
This can be done in two different ways.
1) Unmount the radiator if it is installed in a PC case then gently shake it to loosen any air bubbles.
2) Lay the radiator or system on its side and let it run for until the sound goes away. It can take about 15 minutes before the sounds go away.
These methods are also recommended if drastically high temperatures suddenly occur.

The pump is in the card. So if their was noise caused by trapped air in the pump one couldnt free it by playing around with the rad. Unless they wana free trapped air from the rad (where ya want it) and move more air to the card/pump.

Tilt the case while on load (gaming/benching) so the pump ramps up in speed. Tilt the case so the liquid connections on the card are facing up.. tilt it to the left and right a few times so any trapped air hopefully moves to the exit line to the rad..

Any trapped air will hopefully stay put at the top of the rad. Hopefully you installed the rad the preferred method with the rad higher then the card and with the liquid connections at the bottom.

Noise on a pump is 2 things.. usually air in the lines or just a bad designed loud pump.

Always when filling and bleeding a water cooling system the pump is loud at first and quiets once all the air bubbles are gone.

I tilted the case on it side I run benchmark for 30 min, when I was doing that I Unmounted the rad and shake it, and tilt it to the directions and nothing changed.
 
should I let it benching when I go to sleep/ work ? will that might help with issue ?

How is your mounted ?
 
I fixed your link in OP
 
 

Radiator above the gpu tubes down like in the picture that came with the gpu
 
thanks

You could let it run 3 or 4 hrs while your home & see it it helps any
  
Even @100 volume I could barely hear the "noise"

after 6 hours the buzz still here with no different at all
 
if you mean my recording, maybe it's not showing correctly what I have right now, but I can assure you that is unbearable 
 
I contact evga support for RMA yesterday but did't receive an answer,, did they work on weekends?

I'd keep it slightly inclined so the rad is taller so the air stays there.

 
Do a forum search for pump noise or buzzing, you will see it's not just bubbles but the nature of the pump.
 
Some people have better hearing than others

I had a similar challenge with my old 1080ti SC2 hybrid. Since you are not able to adjust pump speed in the software, I bought one of the cables below to hook the pump directly on to a fan header on my motherboard; I set it to 60%. That said, not sure if the newer hybrids use the same connector...you’ll have to take off the plastic cover and look.

While this isn’t your exact card...it illustrates the general process.

Only need to remove the shroud.

I have/had this same issue. Pump sounds like a fridge condenser. I've reduced it by about 50% subjectively by sideways tilting the case for a few minutes, returning it upright, and then gently but firmly tapping the front case legs on my table, several times, to shake the card. It has removed some but *not* all of the higher pitched refridgerator buzzing, and now has a subdued (but still audible) pump noise. 
I do not want to play card roulette with RMAs trying to find one that is dead silent. I guess I can live with this, for now. 
 
I have my card mounted vertically with the vrm fan facing outwards, and radiator hoses on the bottom, radiator higher than the card. I however, do not have temperature issues, as with a BeQuiet fan controlled by the card it never reaches above 62C overclocked.
 
I came from a 1080 Ti FTW3 Hybrid that was silent in comparison.
 
Must be a cheaper pump unit from Asetek. Along with a chirping VRM fan when it starts and stops, not entirely impressed this time, EVGA. 
 
Just my 2 cents.

I got a 2080Ti XC Hybrid. I've used the last 2 generation of Hybrid coolers which have had some mild pump noise but nothing like this. This sounds like I'm running a mini-fridge on my desk!
 
I called EVGA and followed all the routine troubleshooting steps of rad position, shaking the pump, etc but the noise persisted. This is definitely an issue that is intrinsic to the pump. The rep I spoke to even told me that I could RMA but there's no guarantees it'll fix it. They claim this "mild hum" is normal. I think that's utter nonsense, for a $1500 card, there should be no compromises. I thought about returning this one and getting the MSI hybrid but that had HORRIBLE coil whine so stuck with the EVGA one for now. 
 
Eventually I did do the voltage mod thing, where I took the pump header and connected it to the AIO header on my mobo - I've set it to 60%, that's where I can still hear the noise but it's very minimal, anything higher it was still audible. I ran tests with the pump at 60% vs 100% and after a 1 hour heaven benchmark run there was only a 1 degree Celsius difference. So for not i', going to use the pump undervolted and see how it goes... It's sad that no company can come out with a decent hybrid card at this price point and EVGA insists on ignoring the issue and calling this a "normal mild hum"

you shouldn't have to go through the trouble of ripping the shroud off just to hook the pump up directly to the mobo. I really hope that Kingpin isn't going to be using the same pump. I still have no idea why they don't think this is a problem. I'm waiting for my RMA replacement and hope it's not as bad but from what I have read it seems like it most likely will be as loud and obnoxious as the current one. I'm half tempted to ask them to send the air version instead.

same here I sent my card for them, It should deliver tomorrow.
I asked for the air version if possible , I can't RMA my card again, the shipping cost me about 70$.
So I wan't to be safe with the air card. 

Received my replacement. It was a brand new unit. Same loud whining noise from the pump, like something you would hear from a refrigerator. Temps and Performance are stellar but the noise is maddening. I upgraded from a 1080 ti Hybrid which was whisper quiet.
