Hi
I have recently changed my GTX 970 with a Palit Super Jetstream 980 Ti and was all fun and dandy until i started having game freezes that resulted in system reset. Upon further investigation regardless that the card was OC or not the backplate was getting very hot, could barely keep my hand on it mainly on the side with the memory.
I have used Thundermarster and MSI Afterburner to control the fan speeds and do some OC tests.
Odd thing is that with a burning hot backplate the actual GPU temp were kept in between 45-55 C tops at all time with fans running at about 50-70 %, so it was not the GPU that was heating the backplate.
Any ideas before before i RMA it?
My system spec:

I7 4790k OC-ed to 4.6
Bequiet Dark Rock 2 cooler
Asus z97 Mobo
4x4 Gb DDR 3 Kingston memory stock at 1600 mhz
3xSSD
1xSATA
1xCreative Soundcard PCI-e
Bequiet PSU 850 W
Corsair 780 T case.
Cheers!

As was mentioned, the whole point of the backplate is to increase cooling of the graphics card, and particularly the GPU. But that backplate heat has to go somewhere. The fact that your GPU temp is staying reasonable suggests that the backplate is working properly. Have you taken a look at the system board and CPU temperatures?
If the graphics card is physically close to the CPU or other critical motherboard components, and is not getting enough air across it to cool it, then that might be an indicator that the graphics board is adding heat to the interior of the computer, and that heat is not being sufficiently moved to the outside of the case, Just adding fans may not be enough if the fans do not increase air flow - it's possible to add fans and worsen cooling when the fans are oriented so that they are working against each other.

Going to re-arrange the HDD cages and slap a vent on one of them that blows straight on the video card and see if that makes any difference.
CPU temps are good and there is about 3-4 cm distance between GPU and cooler/ram with more than plenty of room for aiflow.
Had OC my previous GTX 970 ( no back plate) with no issues except for some extra heat getting out of the case.

Found a solution to this:
I've purchased a PCI slot dual fan: Titan TTC-SC07TZ (RB) VGA Cooler with 2x 95mm and mounted it to blow air downward the back plate. This can be swapped to blow air off it aswell and has a vent controller in the back for adjusting speeds.
Got liquid cooling for the CPU( Hydro H90) to exhaust to top of the case
Added SP140 fans to front and back as well to top of the case in the remaining slot and the problem diminished.
Backplate still gets hot, but not at the point where it burns your fingers and both CPU and GPU temps are kept in the low 50's both OC-ed.

Hi, i have the same problem, added a lot of fan and liquid cooling ok but in my opinion this gpu is really too hot. With fan at max speed gpu is near 45/50 c but the backplate is burning i can't touch it also after 10 minutes play. Never had crash but my hard disks now Reach 45 c and is too much .

A thing that i have noticed is to leave the fan speeds actually lower/medium, this way the GPU gets hotter, never pass 70-75 C, but the amount of heat dissipated in the case is a lot smaller and the over all temps for CPU and GPU stay stable.
I managed to crash the card a couple of times and even got a total shut down on system, with the card OC-ed to 1503 due to the fact that GPU and the Case fans were running 100% and the plaxy glass on my case was getting hot, way too much air dissipated in the case! Now i'm on around 50-55 on the GPU and 45-52 with the CPU with the vents on low or medium.
See if this does anything for you.
I don't like the idea of any PCB getting this hot since i had 2 years experience with manufacturing these. The soldering around the components degrades due to high temps and weakens the connections. So regardless of what the companies say: ' It's OK to be hot", it is not OK to burn your hand when you touch your precious GPU!
I will personally sell my 980 ti and wait for next gen and see if there are heat issues with the flag ship model of Pascal as well.

The backplates are supposed to be hot. They all get hot. Its the card itself getting hot. 55c is 131 degrees F so thats pretty hot to the touch. My 780ti's with the backplates also get hot when gaming ot benchmarking. They are supposed too.......Gpu's run hot thats why they have fans. As long as your core and memory temps are within range the excess heat coming from the backplate (which acts as a heatsink) is normal. Try playing with the side panel off your computer and see if you get anymore shut downs. It could be other things inside your case getting hot and your case may need better cooling.
