Like some of you, I was a bit disappointed with the temperatures of the RTX 3080 Ti. Compared to my Asus Tuf 3080 OC Edition, the Ti temps were about 10-15 celsius higher. This is what solved the issue for me:

1. Undervolt the card to .800 @ 1715 Mhz.

2. Set a custom fan curve to about 55% fan speeds between 45 degrees celsius to 55 degrees C. Under 45 degrees, you may set the curve lower as you wish. between 55 degrees to 65 degrees, gradually set the fan curve slightly higher than 55%, but not exceeding 65% up to 70 degrees Celsius.

3. Make sure you have a case with adequate cooling. I previously had a Lian Li Lancool 205 which was not bad, but certainly not meant for cooling. Switching to the Corsair 4000D Airflow case alone shaved 10 degrees off my gpu temps.

I am now running between 49 to 54 degrees Celsius when gaming at 4K Ultra settings with Ray Tracing enabled. Games like Modern Warfare or Warzone now run in the high 40’s to low 50’s. Highest that game has hit is 53 C which is significant from the 70+ C that it was running at before. Best of all, the PC is quiet and does not heat up the room.

In result, I have had absolutely zero issues with the undervolt and I do not seek liquid cooling. I’m completely ok with Air cooling the gpu. Every single title in my library runs great at 4K max settings.

Best of luck!

at what FPS though?  I'd be curious what your 3dmark/portroyal scores look like with that undervolt.

I typically lock it to 60fps using riva tuner software. I have never dropped below 60fps, no stutters, no tearing of any kind. I will run some benches later and update this thread with the results.

Good deal, I look forward to your results, 60 fps is too low for me personally, I'm more of a 140+ FPS @ 1440p kinda guy :)

I hear ya. I may run some tests at 1440p and update with the results. I don’t expect the temps to change much. Native 3840 x 2160 @ 60Hz, Max settings with RT enabled is ok with me. Considering that my temps at 4k 60fps were high on this card before, I consider this a win. Low thermals and quiet operation at 60fps is a bigger priority for me than sweating in a room with jet engine noise.

looks like techpowerup is getting the same temps as me so im not gonna worry about it

The only problem with the hybrid kit is you can't control the pump so it's sounds like a constant mini fridge in your pc at idle.

My FTW 3 Hybrid is dead silent for pump noise. Might be just luck of the draw...

So essentially pay $1500+ to turn the card into a $700 3080 or $600 3070 Ti?

This is ridiculous. People need to stop worrying about temperatures if it means gimping your card and underclocking it to perform worse than a 3080.

If you card is running at 80C, that's not a problem, it's not going to kill your card and you don't need to turn it a 3080 to help you sleep at night.

Reality is, even capped at 1800MHz, with the voltage turned down, it still probably benchmarks at very near stock levels if it's running hot to begin with. Not a Ti version, but my 3080 was down clocking to 1760MHz with stock settings in Port Royal. Undervolting to ~800mV@1800MHz actually made my score (marginally) higher then stock.

Fan curve changes and then finding the lowest voltage that could run 1950MHz did get me ~700 points higher though.

The hybrid setup definitely made for better performance all around. It's more quiet, runs cooler, and clocks higher.

This is simply not true.

 It is though. This has been a well known issue with the hybrid kits. I have installed two on my 3080. There are online videos of getting a 3 pin fan adapter to control the pump as a mod even. If you can change the pump speed to reduce noise without this mod you have a unicorn model.

Straight out of the box without raising the power slider up or anything, the card with the normal BIOs and OC BIOs should be hitting and averaging 1860 MHz. 


 
That's without raising the power limit to the max. Downclocking it so it never goes above 1725 MHz would lower its effective clocks by 7.8%. 
 
But if the card even reaches 78-85C, why worry? It's not going to kill itself. These cards have thermal safeguards. It's not worth turning the card into a 3080.
 
I'm all for undervolting but OC, not underclock. Underclocking the card to neuter it sounds like a waste of $1500. The OP can do whatever he wants with his card though, it's his. I'm just expressing my opinion that the paranoia about temperatures is getting out of hand when someone buys a $1500 card and turns it into a $700 card because of a unreasonable fear of a card running with safe temperatures.

I don't know, I don't have that problem but maybe my case has better noise reduction than yours? I'm running a Lian Li Dynamic XL. When all my fans are running idle, like 600 RPMs and dead silent, I can hear a slight hum coming from my Corsair H150i and the Hybrid but I have to put my head close to my case. My case also sits to my right on top of my desk. 
 
But it's nowhere loud enough where I would consider purchasing an adapter. 

This is weird I have the dynamic case as well.. my friend and I both have hybrid kits and it makes a constant buzz. Steve from gamers nexus even addresses the mod to fix this on one of his videos. The pumps are to ran at 100%. Jacob has addresed that they don't have any plans to change the pump either.

Can someone confirm that msi AF latest version 463 working properly for all settings for OC,and for all 3 fans on evga 3080ti ftw3 ultra.since i can see only gpu 2 tachometers in msi settings monitoring tools for OSD

Can anyone sustain 2,100 Mhz gaming at 4K on one of these?

Yes. People who are on water and won the silicon lottery or people who are lying.

thanks.
