Quietest 120mm or 140mm AIO for GPU?

Wondering what the quietest AIO cooler is. Going to use it with a Kraken G12 gpu bracket. I have a gigabyte gtx 1080ti with the 3 aftermarket fans, but they're still pretty loud
 
That's a pretty small radiator for a 1080ti; it'll have to run flat-out to keep it cool under load. Plus, that bracket will cool the core only, so you'll still have a fan on the card for VRAM and VRM cooling.

You might get better thermal performance, but it will not be quieter than the stock heatsink.

120mm is plenty. Guy on YouTube used an h50 unmodded and kept it under 50. Just wondering what's the quietest

Did guy on YouTube happen to mention what speed he was running the fans? Or what software he was stress testing it with?

Like I said, it'll cool it. It just won't do it quieter than the stock heatsink. I guarantee that three-fan heatsink has more surface area than a 140mm radiator.

Get a 240 or even a 280 AIO to throw on there, and you'll reduce the noise factor. A 120 is undersized for a card of that TDP.

If silence is your goal (as is suggested by your OP) you'd probably be better served just dialing in a less aggressive fan profile using MSI Afterburner or similar.

Want to lower the temps first and foremost. When those 3 fans ramp up they get really loud...seems like louder then the reference 1080ti i had. Might go 240mm route

(thick) 120mm rad will do if:
1) ambient is around or less than 25 C;
2) Load temp desirable to be around 50.

25 C water delta (from my experience AIO suprisingly has ~1 C delta betwean water temperature and GPU temperature, my custom GPU waterblock has 6 C delta...) will suffice for many watts of heat dissipation even with 120 mm (around ~280 watts to be exact, its explained quite well here http://www.overclockers.com/guide-deltat-water-cooling/) at 1000 RPM (which is tons quitter than any "solid state" solution). So with any "decent" (had Antec 920 and GTX 980 Ti matrix which has the same TPD as 1080 Ti) AIO will keep gpu under 50 with ease (as long as ambient is at 25 C or less). VRMs are are too quite easily kept cool by pretty much any fan on earth if they have any sort of heatsink (but yeah, you have to look if VRMs heatsing is part of main heatsing or if it a separate heatsink, nudes help a ton).

The guy on youtube with the 1080ti put on heatsinks for the VRM, but took them off after other people had success without any heatsink

Very informative. Thanks. I'm looking to put an H55 on a 1080Ti via a Kraken G12. Sounds like it should be up to the task.

The hybrid versions run 120mm and are reviewed to be very quiet- having one, it ain't dead silent, but it's quieter than one of the dual-fan 970's it replaced under load. I'm looking forward to the release of the 2080Ti variants, and then later going on sale...
