I have two 1080 Ti SC2. I also have two hybrid coolers from EVGA, which I installed myself. Both are experiencing a serious problem where they make a roaring noise whose volume rises and falls in a repeating pattern. It's hard to describe — but it's super annoying when it's your personal PC! The noise from one of the two progressively worsened to such an extent that I needed to remove the hybrid cooler; now the second unit seems to be experiencing the same problem.
Is it possible to perform some kind of maintenance on the closed loop cooler (CLC) to fix the problem? Alternatively, does anyone have a contact at Asetek that can sell the CLC itself to replace the part? EVGA does not sell any parts for the units, unfortunately. That undermines my confidence in EVGA's commitment to the units. If the pumps are the weak link in the system's reliability, why not keep replacement parts in stock for them?
When I shake the radiators, I can hear the liquid sloshing about inside. Is that normal?
And before anyone asks, installation was according to the instructions — the radiator was always above the graphics cards. Initially I had one radiator mounted horizontally, and the other vertically at the case's top-back outlet (tubes at the bottom). Curiously, several weeks back ago I moved the vertically mounted radiator to join the other radiator at the top of the case, so they were both mounted horizontally. The noise then completely disappeared for a week or so, only to come back more loudly than ever.
Finally, I've been running both GPU 24/7, typically at 70% power load. Whether running them continuously contributed to the problem, I have no idea.

Are your hybrid(s) still under Warranty ?

Thanks Sajin and Cool GTX. I didn't know about the Kraken products.
Perhaps this thread is better placed in the EVGA CLC/HYBRID Coolers forum? If so can a mod please move it?

I would also wonder about air. For the radiator is the cables at the top or the bottom? Best way to have it is above the card and the tubes coming off the bottom of the radiator instead of the top. That way if any air exists in the setup it will rest at the top of the radiator while the tubes are filled with liquid. You can even if you want to hold the radiator outside the case to help insure that any air goes to the top of the radiator. Just watch out for fans and be careful when you turn off the system and mount the radiator to keep the radiator so air Is trapped at the high point instead of entering the tubes.

Check for the cooler of the two hoses or Contact EVGA CS -- to confirm your GPU would also be like this Worth Noting on the FTW3 Hybrid mounting - the suction (pump Intake) hose can be the only hose at the bottom of radiator

Hi Damon, Sorry for not responding sooner. Pesky timezones... CET!  I saw that Shawn (Asetek I'm Hit) might've already adressed this. To address a couple of your initial points: - Some slushing is to be expected - however it shouldn't be too much
- Do you have a recording of the sound they make? I'd be interested to hear what sound they're making.
But I totally get your frustration over any non-expected sounds. I hate that scenario myself. Shawn is in the US, so your timezones might align, and we'll do our very best to find a solution :)

Hi Dennis and Shawn, Thank you very much for your prompt attention. I was away from my computer today and unable to respond until just now. I have created an audio recording: https://damonlynch.net/sh...80ti-noise-problem.mp3 Some notes to go with the recording: - I removed the case's side panel and placed the microphone right beside the GPU itself, close to the tubes without touching them.
- There are 2x 1080 Ti in the system, but only one has the hybrid cooler as I had to remove the other hybrid cooler one due to excessive noise, whose noise like this recording but with a louder roaring sound. The radiator is mounted vertically above the GPU with both tubes at the bottom (i.e. the radiator is in the back-top of the case). But if the radiator was mounted horizontally at the top of the case it would make no difference.
- During this test, both GPUs are idle; the GPU with the regular EVGA double fan setup has its fans powered off due to being idle.
- Another way to test would have been to place the mic on the other side of the room. It would have still picked up the roaring sound. I can do that if it would help.
- The sound to listen out for is the roaring sound, which comes and goes at approximately 15 second intervals (roughly). You can hear it from a few seconds in. Outside of this recording, the roaring sound might disappear for a minute and then reappear more regularly than the 15 sec repeating pattern during another minute.
- Of all the GPU sounds, the roaring sound carries most clearly outside of the case. For instance, the sound of the liquid moving in the tubing is not audible outside of the case.
- I have confirmed the noise is not from the Noctua CPU fan or the Fractal Design case fans. Those fans are really pretty quiet.
- The roaring noise pattern starts immediately as soon as the PC is powered on, before getting past the BIOS.
If you have any questions please let me know. Damon Edit: I added the link to the recording

Overnight the surviving GPU hybrid cooler died. The pump noise became constant and very loud, and the GPU temperature was in the low 90s. I don't know how long the temps were that high for, because it happened at night. Hopefully the GPU has not had its lifespan affected too much. The noise woke me up while I was asleep in another room

Hi Shawn and / or Dennis,
Is there any update to report regarding this issue with the two hybrid coolers I've had?
Thanks.
