GPU too hot?

It's normal to reach 79 celcius while rendering with the gpu?
How can I know if my gpus are working? I only have two 980 ti. Both reach the same temperature with the fans working. That's a good sign to know if my gpus are working?
Thanks!

Also my render stop at 80%. It had happened before. It's normal too?
My GTX 980 Ti runs at about 72 degrees when rendering an Iray image. It has run over 80 degrees running the Steam VR performance test. Mine is an EVGA card and I use EVGA PrecisionX 16 to create a custom fan profile to run the fan a little higher than the default speed when the temperature gets up that high.
If your render is stopping, have you checked your Render Settings to be sure the Max Samples, Max Time, and Rendering Converged Ratio are high enough? These settings are under Progressive Rendering. I haven't heard of a 79 degree GPU terminating rendering. 79 is still below the temperature at which things get throttled down (83, I think).
The cooler, the better, but 79° still is inside chip specifications, or to be more precise specifications for GTX980Ti list a max. temperature of 92°:

But as this configuration heats up the whole case and system components, you might think about checking your case for better airflow with additional fan options, better airflow (e.g. air goes inside case from one side and out the other way) or a better 3rd party cooling solution for the GPUs. Some GTX 9xx graphics cards are known for thermal problems if mounted too close together as well (one card blocking airflow for the other one), depends on your board if you have other options to install.
I have two Zotac AMP Extreme 980TIs and the first one runs up to 83C due to its position in the case while the second runs about 20 degrees cooler but both run at full speed.
The design temp for the 980ti is 79C. If you don't use custom fan programs, the driver will ramp clock speed up until either the design temp or the TDP limit is reached.
In my specific expereicne my 780 would run right up to 80C at 50% fan speed and sit there. My 980ti will ramp up to 79C at about 70% fan speed, but it has also ramped the clock up to 1320 (from a supposed boost clock of 1190).

If your gpu is at 79C, it's working. It should normally run in the high 30s when normal desktop apps are running.
If your render stops at 80%, one of two things is likely: either you reached your max samples setting, or you reached your max time setting. The defaults for Iray in Studio are 5000 samples and 7200 seconds.
Another possibility is that your "rendering converged ratio" got set to 80%. The location of these settings is shwon in the attached image.
You need to get liquid cooling. They are compatible to high end fans. I can have my machine at an extremely heavy load and it don't get any higher than 36C
Only if you trust water cooling which I do not presently
there are 2 different system. One that you fill yourself and an enclosed system.
Thanks for all the answers!
Samples are set at 10000 and the time max is 20000. Those are default. So... I have a problem?
And if you can get one of the hats that takes an extra can or two you're set. Don't skimp on the straws.
It is hard to know whether that is enough. It depends entirely on the scene and your rendering GPU(s)/CPU. What Mec4D can render in 10 minutes on her 4 TitanX Hybrids would take somebody with only a low end CPU many hours, I'd guess. Do you know whether your render is ending before 20000 seconds (5.55 hours). (Oh, and those aren't default values; they are larger than default, so you've already taken the first step.)
I've had my system for 5 yrs now without a hair of trouble. The only thing I have to do with it is clean the radiator and fan. My wife has a custom built system that we have to fill and have professionally cleaned once a yr. Neither system have given us any troubles.thats the whole point to enclosed systems. They are welded shut and don't leak. You would have to take a hammer to it to break it open. To each its own.
A couple of points.
Water cooling is SUPER if you want a QUIET machine. I use water cooling for my CPU, but I use the stock heat sinks/fans on my GPUs. Will water cooling make your components colder than air cooling? No, because that's not how thermodynamics works!
Whether you are using water or air, you are doing the very same thing: You are moving heat energy away from the hot components to the air inside the case and then to the exterior of the case. Heat is energy, cold is not energy. Therefore, you are not moving cold to the components, you are moving heat away from the components. This works the same way that a car's engine works. And yes, some cars are air-cooled.
Use what works for you. Me, I can't use a computer with loud fans blowing. I get fatigured over time, and that makes me much less effective.
In my experience, a closed-loop (pre-built and pre-filled) water cooler will last you between 18 and 24 months if you run it full bore 24 hours, 7 days per week. Yes, I know this; trust me. Eventually, the coolant inside will become nasty and will emulsify/break down. But for a hundred bucks, it's worth it not having to design, build, and maintain one myself. Just getting the right parts is a major hassle. But water is quiet, so I want water on my CPU. Don't need it so much on my GPUs because the major graphic card makers usually have pretty good built-in fan management.
I say get your money's worth out of it, then junk it and get a new one.
I noticed that if i change the render resolution that settings changes too. How can I do to make it immovable?
If you reach 80C you starting losing the speed on your clock and your cards will render slower than it should, no matter it is rendering or games , for air cooling cards the only solution here is side fan , I have in the begining air cooled cards and the same problem as yours , after I installed the side fan the temp dropped to 67C and everything was fine again , now I use closed water cooling with independent radiator for each GPU and everything run at 37C . I am not sure yet if I want central Water cooling as it will give me no more as I have now .
If you PC case allow you to install side panel fan go for it , also if you don't have already buy backplates for your cards it will lower the temp also around 3-5 C by cooling better the VRAM that is outside of the card that can get very hot and actually is not cooled by anything but the air in your case heating up the rest of the components on top of that .
The secret in cooling right PC case is in creating the right pressure , so fans running like crazy may cool less than slower fans , also you will never get lower temp than your ambient room temp unless you use nitrogen ;)
1.Backplates
2.Side fan
that are all option you have here but with possible good result as I did and it worked . Or get yourself EVGA Hydro Kit for your cards and forget about the rest , your warranty will be not affected as long you keep the original parts just in case. I did with my 2 early cards as well and that was the best choice ever and the fact that everything will be protected by warranty even if something leak make it even better .
Cath, for the side fan, should it blow in on the card or exhaust out? My front fan blows in and my top and back fans exhausts out
the side Fan need to blow on the card so intake the air from the side panel , it will cool of the v-memory that are on top of the card and reduce overall temperature , I tried before the heat sink on the v-ram but did not worked as good as backplates , one day it was so hot it started melting slightly the rubber tubes of my CPU water cooler that was not far from the card, then I switched to backplates and side fan and problem was gone 67C max on full load air cooling , for that reason my additional cards was already Hydro and I upgraded my other 2 with the EVGA kit as that was too much for just 1 side fan, but for 2 cards the side fan worked well
You have the stock Titan X right? without backplates , they are around $29 and easy to install on top , if you have no option on the side for the fan you may have option on the bottom of the case or you can buy VGA fan and plug it into free pci slot above your card , it will suck the hot air out
Take the side off and put a portable refrigerated air cooler by it
I did this for Octane last 47°C heatwave, worked a treat.
You can also try this one Click here
or this one in case you can't do the side fan
works best when it is above the card or between 2 cards
Thanks for the information, Cath. I have an EVGA 980 Ti. My case has a place for a side fan right by the graphics card.
Then you all good .. now only fan and this you screw it on top using the included screws, very easy, it will protect also the card from eventual dust particles and much easy to clean and handle and the big area will cool off the v-memory efficient with the side fan reducing the card temp
I take the side off when I'm rendering. My 980Ti stays at around 68C

I've always been told that removing part of the case disturbs the airflow to the whole system.
And that is very correct , the PC will lose the presure, your motherboard temp will rise and so the RAM temp , it is not good for the system unless your CPU is water cooled and you have RAM cooling
I have Open Wall Case with front glass only but everything is water cooled so not need air presure and I had to install RAM cooling as well as it reduced 20C temperature, without it was not good
My Kepler generation Titan is typically at 30'C. With multiple CG progs at 40'C max.
Launching Daz Studio sent it straight up 20'C - 28'C and double fan spin - even with Draw non-Nvidia, and render setting set to 3delight, no iray shader in the scene.
Not sure if that's normal...
I use CPUID HWmonitor.
Driver issue , It should go up when you start DS and fall down back to where it was but instant it keep the clock in standbye mode and that is 100% driver issue
In my case, I have 1 front fan, 2 side fans, 1 back fan and 1 top fan
since hot air rises I set my fans up like:
the front fan (which is towards the bottom of the case) and my bottom side fan are pulling cool air in
Then I have my top side fan, back fan (which is towards the top of the case) and the top fan pushing all the hot air out
It's been working pretty good for me for the past 5-6 years :)
That is perfect setup for the max air presure and flow , I had it like that in my last rig when my cards was still air cooled , zero issues
