Hi all,
 
I got my hybrid kit and so far almost happy with it , I don't think I hear any "loud" pump noise , I can only hear the pump working when I put my ear next to it (they do have to make some kind of noise since they are turned on ) so to me that might be normal noise. My issue seems to be one of the tubes is vibrating really hard non stop, the other tube for example vibrates but very light and hardly noticeable.  This is making my case rattle , when I put my hand on the side of my case I can feel the vibration.   So my question is are the tubes supposed to vibrate at all?  what about the intensity? 
 
Thanks in advance for any clarification , I need to know if I have to RMA this unit (i hope not)  if both tubes were vibrating like the one that is hardly doing it , very light I would be ok I think. 

It sounds like there may be some twisting or other constriction in that line.  You can always feel it to some extent as the fluid is forced through the hose, but it should minimal.

Hey all,
 
I've just had by 980Ti Hybrid in now for a couple of days and I'm getting the exact same pump noise as in the video above.
 
The noise is horrible and very audible in a quite room when not gaming. So much so I want to RMA it I think but just like vegnar I want to know if this is common across all Hybrids or an actual fault.
 
Don't want to return it for another card that just makes the same noise!

Bottom line: if you're not happy with the noise, then RMA. If you can live with the noise and temps are ~50C and below, you're fine.

Not exactly that straight forward. I don't want the hassle of 2 RMA's if they all make that noise, as in that case I'll return it and get something else

They don't all make that noise, a small minority do. I can tell you I have 2 and neither makes any noise.

That's good news, I think that's kinda what this thread is about, just getting to the bottom of the noise issue and if it is in fact normal.
 
I'll give the RMA a go now then :)

Yeah its mounted as a rear exhaust with hoses at the bottom. TBH though i've tired it in every orientation and direction and the pump buzzing doesn't stop

Yeah bro, unfortunately an RMA is your best option.

Your comment does not exaclty help at all here but I won't turn this into a flame thread. Instead you could help us by telling us if your pump makes any noise or if it's silent.

As someone else stated is not that simple , I myself dont mind some noise but I prefer a nice smooth air sound than a buzzing noise. Again I purchased this kit because they claim to be cooler (and they are ) and very quiet

I already did...

I'm not trying to be a pain here, but we've established that these cards run cool and quiet. If a particular one doesn't either the owner fixes it, lives with it, or RMA's it. This goes back to the OP's post.

Well I got my new Hybrid 2 days ago and it's silent
 
Interestingly this one boosts higher than the other one too.  Striaght out of the box it goes up to 1366Mhz and if I increase voltage to 1.22 it boosts to 1402Mhz but I hit the 110% power limit often so I might be flashing a new bios soon to stop that happening.
 
Anyway glad I did the RMA. If anyone else is reading this because your pump buzzes then get the card replaced!
 
Also I have to say dealing with EVGA was so easy, first time I had to deal with their tech support and RMA team but it was a breeze
Always good to know support is there if I need it from a company, will make me want to by from EVGA again.

Very interesting to know that.
 
Now EVGA need to put Corsair AIO on their cards. 
 

Any of the round bodied Corsair AIO's are the same make (Asetek) as the hybrid pump, so they already do this.

hello, sorry for my very bad english , i like a silent pc, but my evga hybrid pump was very noisy, buzzy. i made some reasearch and the pump only have 2 wire and too control the pump via motherboard i need rpm check, because if you plug the pump directly to the MB fan header the pump will run at max, i renove the plastic cover of the pump and see only 2 wires but a solder point for the rpm, just solder a wire on it and i can control the pump via mb. and i make the pump running always at 1500rpm and now is dead silent, the fan are directly connect to 12v psu, they run always at max 1200rpm and very silent, my temp have decrease about 10 dg, and run at 1500 mhz at 40/41 dg playing battlefield 4 at max
 

For anyone who is curious, EVGA has confirmed that the above modification will void the warranty. It is not clear if they mean the card's warranty or the hyrbid cooler's warranty. Regardless, proceed with caution and prepare to accept the consequences.

I have a 980 Ti Hybrid and also just the 980 Ti Hybrid cooler. Both make the same exact little hum noise when powered on. This is normal, in my opinion. My H105 and my friend's H100i make the same noise too.

GTX 970 hybrid user here. Can confirm that the pump is extremely noisy. Already ordered a replacement from Amazon. The second one is slightly better than the first, but the noise is still not acceptable. 
 
I have removed the fan on the radiator and am sure that the noise comes from the pump. Besides, the tubes vibrate a lot and may result in resonance with case. 
 
I think the problem here is that the pump always works at full speed. It seems that the selling point of this card is low temperature due to water cooling rather than quietness. To be honest, this card can be quieter than air-cooling cards when under load, but it is a lot louder than air-cooling cards when idling since air-cooling cards can completely stop the fans when idling.

Hi all,
just thought i'd share my recent experience. I have a 970 Gtx Hybrid, runs idle at 22°c, loaded at 38°c. There was no audible noise worth mentioning from the pump or the fan. Fan speeds are at constant ~1100rpm-1200rpm. Awesome.
 
Everything was running smoothly until I woke the computer from sleep on day 2, the temps at idle was at 45° and a quick 2 min in game and the temps were up to 90°c+, fans at max and etc. Rebooting/unplugging does nothing.
Likely suspicion was that the pump is not running for some reason. Left it there for 20 min or so whilst I was writing up my RMA, the temps suddenly dropped and its back to normal (??)
What I've found is that, to tell if the pump is running, gently hold braided tubing, if there is a slight vibration on both tubes (fluid is moving), the pump is working as should. Mine is even and it feels like a soft hum. Uneven vibrations is likely due to possible blockages (restrictions in the flow) or impeller issues causing uneven water pressure at each rotation.
 
If you don't feel anything, the pump is likely dead leading to high temps. I'll keep a watch on mine for the meantime. 

I can confirm soldering a 3 pin fan cable allows manual control over the waterpumps speed. By default the pump is running at max ~1800rpm hence having a loud buzzing noise as you would expect. After soldering the 3pin fan cable I am able to drop the rpm to ~1250rpm. At this rpm the pump buzz isn't present at all, even when running at 1400rpm the annoying buzz is gone. I have stress tested the card on furmark, running at ~1250rpm resulted in the temps ~68c with a silent wings 3 rad fan running at its lowest rpm, increasing the pump speed to default (max) the temperatures were very similar ~70c with rad fan running at its lowest rpm.
 
I found the constant buzzing extremely annoying and can't comprehend why evga wouldn't allow manual or even automatic control over the pumps rpm and rad fan. With this modification my silent PC is complete. I'm running the EVGA hybrid 1080 cooler on my new Titan XP card and in order to make it fit, you need to slightly modify the baseplate, this voids my warranty already. You can't expect a water pump to be silent running at its maximum rpms, there is no need to rma because it won't change a thing if the pump is operational. As mentioned before this will void your warranty but if you want true silent performance this is definitely the way to go.
