So I guess this one is not that bad. However, I am sure it will still go up if I run more time.  My case is S340, H100i v2 in front pulling air in, 120mm X2 fan one on top one on the rear. 

His sides and front are off of the case, so not real temps shown.

Alright, temps seems fine after all when using the OC bios on the 3080 FTW Ultra.
 
This is stock speed with OC bios, fans maybe at 60% load and temps 69°C, I'm happy :) Not sure if overclocking further is worth it?

Using port royal to test temps is not ideal as it is a short benchmark and typically does not push thermals as high as something like time spy or firestrike. Heaven also pushes temps higher than port royal. I have been using heaven to test different fan speeds and configs to see if I can lower temperatures. I managed to lower temps by about 2c by sitting a fan in the bottom of my case blowing up towards my ftw3. I don’t have a bottom intake so it is simply Moving the air already within the case. Tomorrow my noctua nth2 and thermal pads should be arriving and I will test how repasting and adding thermal pads between the back of the pcb and backplate affects temperature.

To clarify I am running heaven with my ftw3 at 75% fan speed and +950 mem +112 core with max voltage and power target. I have been doing 2 back to back heaven benchmark runs with hwinfo being opened just before I start each benchmark so I can see both max temperature and average temp for each individual run. I also typically let heaven run afterwards without the benchmark for about 10 minutes and track what max temp it reaches. After adding the 120mm fan to the bottom of my case, the max temp I reach in heaven with these settings is 68c, down from 70c without the bottom case fan. I am trying to remove as many variables as possible, but ambient room temperature cannot be controlled perfectly as I’m in a fairly small room. With this in mind ambient temps should be between 70-72 Fahrenheit. Ideally replacing the thermal paste and adding the pads to the backplate will reduce temps by 3-5c. That would most likely allow me to use a less aggressive fan curve while maintaining similar temps to what I have now. I’ll keep you guys updated on what I find.

Yeah. Well. TUF is good. Not sure FTW3 can do better tbh I guess we'll have to wait for his review too. The Strix probably will though.

Yup if I could find a tuf that would be my #1 choice. I have a msi gaming Trio on backorder from provantage but who knows when it will ship, they took my order on 9/18, the trio can do tuf like thermals when you match the rpms. But like many here we are on evga queue system, I would wait for the trio to actually ship but I don't have a gpu on my system and can't use it because is a 3700x cpu (I built it back in August) was hoping to get a 3080 Sept 17 and we'll now it's been 2 months and can't use my computer so I'll grab whatever comes first and it's looking maybe like the evga card but I'm concerned it will be toasty.

People make such a big deal out of case flow because it's the low hanging fruit, but unless you're an absolute idiot it's really not THAT large of a factor. I have a HAF-X, aka the best case for GPU temperature ever made. I did an experiment for you to prove my point. Running 8K Superposition with auto-fan on my XC3 Ultra, my ending temperatures were as follows.
 
With the case completely open: 77'C
With the case closed normally: 78'C
Blocking my side intake fan with paper: 79'C
Blocking both my side intake fan and bottom intake fan with paper: 80-81'C
 
You're not getting a 15 degree swing because of your case unless its a literal bunker. These cards are toasty.

 
MOST people don't have that case you have..
 
Or even the case I have, the Cooler Master  - Master Case 5 Pro, another great case for cooling and airflow.
 
Then if they are water cooling most seem to have the radiator blowing hot air into the case and in a case with poor airflow in general. And not enough fans in the case exhausting the hot air.

No kidding.. that's the entire point of blocking the fans. To show it doesn't matter.
 
And if anyone has any doubts left, here is JayzTwoCents testing a FE edition in comparison to eVGA. Same case, same room, literally 15 minutes after eachother. https://youtu.be/mJ4ha0zsWHw?t=576
 
eVGA is unfortunately the problem.

 
Actually no...
 
The FE cooler exhausts air out of the case.. Like the Older blower fan cards did/do.
 
Saw the video when he 1st made it.
 
And with my case, I just have 2 fans intake and one exhaust fan, air cooling the CPU NH-D15. All the fans that I really need in the case with my setup.
 
My 3080 FTW3 Ultra temps are in the low 60's normally when gaming.

C'mon man, why is it that every post I see you make I feel the need to correct how badly you are being WOOSHED. Read.

What are you talking about.....????
 
My case is what it is.
 
The setup is what it is....
 
The temps I get with my 3080 FTW3 Ultra are what they are....

Come on man. Read what he wrote.
He was comparing AIB cards and showing that the case airflow alone can't -- or is extremely unlikely -- to account for 15c difference in temperature between AIB cards.
He is correct.
Assuming (I can't be bothered to check) that AIB cards are consistently 10 to 15c cooler than EVGA's card, I agree that there is something specific to the EVGA cards which is significantly degrading its cooling performance.

 
Too many variables to say one way or the other.
 
Now they could put the whole machine into a plastic bag, no airflow.....
 
What to know what bad air airflow is?
 
Here is an old PC case... One small intake fan.... The PSU fan would be the only exhaust...

I disagree.  I agree with him when he says that the same wide amount of variables similarly affect the other AIB cards.  If all AIB cards have a similarly wide range of variables (they do), then the average temperature is still statistically significant.
 
You can't argue that it just happens that all TUF owners have excellent case airflow and all FTW3 owners have poor case airflow.  That sounds ridiculous.
 
I agree that there are too many variables to state EXACTLY WHY the FTW3 performs worse than the TUF (again assuming that is true ... I can't be bothered to check), but once you make the determination that it is true, you can then narrow down the "why".  Personally, I am suspicious about the difference in thermal paste between the two; but I could be way off base.

 
I really don't care either.

Then don't argue just for the sake of arguing.

Not arguing, was just stating facts.
 
Even here in this thread there are others, other than me with 3080 FTW3 Ultras that aren't getting HIGH temps...
 
Some however are, one is getting his card RMAed.
 
Now those with XCs, well they are what they are..

I plan on reseating the heatsink with my own thermal paste just for the sake of checking, but probably not before the weekend. I've never had that personally make a difference with GPUs though.

 
I need to do my old 1080 FTW2, I think the paste has dried by now, running a little warm, need to take it apart and replace it.

This os my first time here so hi everyone!

My 3080 XC3 have just arrived and I’ve seen some issues that I’ll share with you since I hope you can help me:

1. I’ve tried to create a fan curve in Afterburner keeping the GPU at 40% until it reaches 40°C. The weird thing is that when I press apply the minimum percentage that the GPU gives is 52% and not 40; is this normal?

2. I’ve noticed a high GPU usage while in Google Chrome randomly, something that I’d bet never happened with my 2080 Ti, is this happening with yours too? I have a 1440p monitor.

I hope someone can help me with these doubts. Thanks in advance!

 
Have to tried using EVGA PX1?
 
IN PX1 using the aggressive fan curve it sets the fans at 40% then they ramp up as needed from there.
 
I don't use Afterburner so I dunno.

Nope I'll try and see how it goes. Thank you!
 
Here is my result by the way, should I be worried by temps??
 

 
 

 
Run it again after you install PX1 and set it.

Thanks for the tip man, run the test again with X1 and temperatures lowered almost 10 degress. Something must be wrong with MSI Afterburner I guess...
 
No worries with these temps right?
