backplate so hot i can't even touch it

Much cooler than in the 90's! :)

Happy with my 150W 1070, so much quieter/cooler :)

This is why most backplates on 390s / 390Xs don't cover the back of the GPU.
 
I think its actually good that companies are starting to use the back plates to dissipate heat.

Most of the time were not touching them unless the card is cold anyway.
 
So I posted about this over in the TXP thread I think, they do get massively hot and its nothing to worry about but heres a couple of things I've tested/learnt with my 1080s:

  1. Backplate of the lower GPU in SLI was much cooler to the touch due to the air escaping the top card blowing directly at it
  2. Top card runs hotter as you would expect to the tune of about 10c (60c vs. 70c)
  3. Added a 120mm fan blowing directly over the top card backplate, resulting in it being significantly cooler to the touch - as in you dont basically burn yourself
  4. Result: Cold backplate, no impact what so ever on GPU temps (backplate is active with pads)

So yes its hot, no it doesnt make any difference but add a fan blowing over it if you are worried.

I have a spare 120mm fan. Would it be best to place under the 980ti? Blowing air into it? TIA

Prob disrupt the fans if its air cooled so no, if you can at a guess placing it blowing across the card front to back is best. In my case I could do that easily with a 120mm mounted on the back of the front rad, you might need to do a bit more work.

Bottom line though, probably makes the exterior cooler to the touch but is not doing anything for the interior components. Cooling the backplate might make 1-2c diff but I dont think much more.

Well it's probably about 78C and that is bloody hot.

What is super hot to us is barely warm to PC components.

This. Unless you are watercooling a GPU it will allways be so hot that you cannot touch ist. 70 degrees for example are considered a very good temperature for a GPU. That is the CPU die though. The VRM's get a lot hotter usually. The VRMs of my R9 290's went past 100 degrees for example. The card starts to throttle once they reach 130 degrees!

Even when you water cool though the backplate remains volcanic to the touch :)
