Hi there folks,
 
I have observed higher temperatures on my 3080 Ti FTW3 Ultra while playing games, around 75c compared to my Aorus 3080 which never went beyond 65c (air cooled). I have set the preset of 'aggressive' on Precision X1.
Although I understand that 75c is a perfectly safe temp for a GPU on load, the noise is too loud and also I would prefer to have my GPU around the 65c mark for my satisfaction.
 
I was planning to go for the hybrid kit, had a few questions before I make that move -
1) Does the hybrid kit make a substantial difference in GPU temps ?
2) Are the thermal pads of good quality that come with the kit ? I have a bunch of thermalright odyssey of various sizes, so was thinking if I can use those instead of the ones that come with the kit. What sizes are those ?
3) Should I replace the thermal paste with Thermal Grizzly Kryonaut or Gelid GC Extreme in place of the one that comes pre-applied with the kit ?
4) Also, I am planning to add thermal pads between the backplate and the PCB. Do we know what are the sizes for those ?
 
Sorry to bother with so many questions. Your help is greatly appreciated.
 
Thank You.

Works well, depending on your case it'll drop temps to 55-65 range depending on your fan profile.

Inreplaces the fans with QL120 for aesthetics and it really hurts my performance. So my temperature is around 65C when pulling around 400W± of load.

The thermal putty is okay, if you want ,take what it comes with and use that on the backplate and use your better thermal pads on the memory modules directly.

Install isn't too bad either.

I'd recommend it.

Thanks Sorry to revive an old thread, but someone on reddit mentioned that he/she is getting 45c on 100% load at 1440p while playing Horizon Zero Dawn. Wondering if that's possible even if we have the best of the best 4 fans in push pull at 100% speed on a 3080ti FTW3 Ultra modded to a hybrid with the kit. I am sitting at 65c on full load in HZD at 1440p on my Ti; sometimes I wonder if the pump/fans are working efficiently/do I have a faulty product or are they bushtting me.

It depends on how much power is being drawn. 300W? Yeah sure. 400-425W? It'll probably be more in 55-60C. 

So you are saying he might be undervolting (due to lower power draw) ? He said everything is stock settings.

Some games don't require that much power draw. I believe when I played Horizon Zero Dawn for a bit, the power draw was low like when I play Assassin's Creed Valhalla.
 
When I play Assassins Creed Valhalla I average 98 FPS, my GPU usage is like 97-99% used so the GPU is definitely being pushed. But the game only draws 300W. 
 
When I play Resident Evil Village, it draws 400W and will go up to 425-450W spikes. That game makes my GPU run a lot hotter. 
 
So what I mean, it depends how much power HZD draws from the card since not all games will draw 100% TDP. 
 
Do you have a benchmark from him I can see? Timespy? Port Royal? 

Nopes. I havent asked for that. But Im pretty sure, for me, when I was playing HZD, temps were in high 60s; so I am presuming the game was pulling 425-450W.

Nah, it's just your setup is kinda rubbish.  I can run my 3080 FTW3 Hybrid at 49C at a solid sustained 445w in Furmark indefinitely, but that's with 3400rpm 120x38mm push pull server fans that are stupid loud.  At normal volume levels and fat 1800-2000rpm maybe 55C.  My 3080 Ti FTW3 Ultra games at about ~425W sustained at 68-70C in 4K VRR, 99% sustained use.  But I have 7 fans pointed at the card and I'm not afraid to crank them up.
 
Also, please do not conflate "undervolt" with setting a "power limit".  Undervolting is extremely dangerous as it can result in a large range of power draws resulting in the accidental overheating of the GPU.  If you can't control a GPU's temps with good fans, reduce the power limit.

Wow thats impressive on an air cooled card.
 
My Lian Li pc 011 case has 3 fans as intake at the bottom, CPU 360mm radiator at the side with fans set to intake and GPU 240mm radiator at the top as exhausts in push configuration. Could you please let me know what part of this setup is rubbish ?

My 3080 FTW3 is a Hybrid and the 3080 Ti FTW3 is the air cooler.  Waiting on a 3080 Ti FTW3 Hybrid that hopefully has better memory.  The hybrid is top exhaust push pull, but with 3 unrestricted strong bottom/front case intake fans and a push pull front intaking 280mm AIO.  So I had insane fans on the Hybrid and very good supporting case fans.  Plus all the extra rear/top venting taped closed to force air through the top rad.  There was a fierce airflow coming out the top at max fans, so much that it blew the dust filter off and you could feel it at the ceiling.  The 3080 Ti replaced the 3080 for now, with the same supporting bottom case fans and front AIO.
 
Your parts are nice, problem is how they are configured or setup which is causing you high temps.  Sorry to be harsh.  The Lian Li is nice but a bit heavy on the glass.  I got a Lancool mesh but also considered the 011 Air. Nice cases.
 
- Most people are citing GPU temps against an ambient temp of 20C and adequate air flow around the PC.  If you have the PC stuffed in a corner under a desk in a 25C room it's going to run hot.  My machine is in free air, on the floor and I've got a 1000CFM vent fan in another room so I'm constantly pulling in cool outside air which gets to the PC intake.
 
- There is a large variation in fan performance on the stock rads.  Some people have taken off the stock 2500RPM fan which are pretty decent if leaky and loud, then put on a wimpy 1500rpm low pressure fan and wonder why their temps are bad.  Push pull can get you 5-9C improvement in temps.  So say if someone had LL120's on the rad, then swapped to the stock plus ML120 Pro 2400 Rpm push pull and ran them around 2000 Rpm, they could expect to drop over 10C in temps.  Noctua A12 are the best combo of low noise and radiator flow.  2150rpm Gentle Typhoons and Vardars are also good.  Can help to seal the fans to the rad with gaffing tape.
 
- Fan flow direction vs. rad exhaust temp vs. gaming res/framerate should also be considered.  CPU AIO intake can be OK if there are other good unobstructed intake fans AND the CPU is running at lower power/framerate with 4K gaming.  For higher framerate 1080/1440p or games where the CPU is working hard and really heating up that intake air, in a 011 it may be desirable to exhaust the CPU AIO on the side and just make sure your bottom fans are good and strong.  Three unobstructed bottom intake fans should flow considerably better than 5 fans on rads plus a rear exhaust.

Undervolting makes a huge difference! I’m running mine at 0.900V at 1905Mhz and seeing 7C less temp on the GPU and 200 less fan RPM with a hair better in performance. It’s definitely worth trying before buying the hybrid kit in my opinion.

Run that on Furmark or New World for a half hour and get back to me.  Thanks!

Back in the day (2011 or so) I developed one of the popular brackets that made it possible to mount asetek liquid coolers on GPU's.  Given the flow rate of these pumps and the radiator space provided I'd either go for air cooling if you'd rather save some $$ or just go with the hybrid kit if you want to save a bit of space.  Dual rads are hard to fit into cases and fail after 2-3 years consistently.  Air coolers never fail, in general are much easier to move between cases.

If you get an opportunity to buy a Hybrid, I would pay the $30 for the 5 year warranty. Worse comes to worse, you'll get a 4080, 4080 Ti or 4090 Hybrid or equivalent if they don't have stock or can't fix your GPU.

Hi KingEngineRevUp - I saw your setup via the MODS RIGS on your profile. The difference is that my 3080Ti hybrid is top mounted as exhausts and CPU side mounted as exhausts. Are you using a push pull configuration on the hybrid ? What kind of temps are you seeing on full load?

What?

Do you need further explanation?  Lots of people recommending undervolt as a cure for hot temps, which can lead to an overheating PC when the user encounters an unexpected heavy sustained load.  I bet half of all undervolted gpu's would get blown out if you ran Furmark on them for an hour.

I have the 3080Ti FTW3 aircooled upgraded to hybrid kit
 
definitely worth it, temps went from 79c on timespy extreme STOCK to 61c on a modest OC with 450w
 
with max airflow mode(no front panel/dust filter) it drops to mid 50s.
 
 
 
 
 
The 3080Ti FTW3's stock cooler is honestly pretty horrible for something this big. Very disappointing to see the current FTW3 generation over the 10/20 series ones
