Yeah they're gorgeous and yeah, totally over engineered but that's also been the problem. The rest of the card is so beautifully made, then they go and slap on a bog standard core so the rest goes to waste.

Two words. MSI Lightning. Three more. Galax 8 Pack.
The HOF is the one - the 8pack 980 was basically just a black HOF

1C difference in ambient = 1C increase in GPU temps.

I've not seen any reasons to believe that. It doesn't make sense either.

It's believable(fact actually) and makes perfect sense. Ever heard of physics?
If it's 20C in the room and the card is running at a Delta temp of 40C, raising the room temp to 21C will also therefore raise the Delta temp to 41C. Delta temp if you don't know just equates to the temperature of the card minus the room temp. That's why some reviewers, like LTT does(used to at least) would get his temps and no matter what would add or subtract to get the ambient to 20C to create a comparable temp reading field by using Delta temps and not temps being recorded by software. OC3D also reports Delta temps if you are wondering.
Another more clear example- this is taking into account constant fan speed to remove variables. Room is 25C. Card is running at 75C. The Delta is therefore 50C. Now raise the room temp to 30C the card will run at 80C and the new Delta is 50C. Now the Ambient(room) is 20C.. card is now 70C and delta has become a 50C. Now if the fan speed was changing and the ambient rose to 30C making the Card 80C, obviously the extra fan speed will bring the temps back down, however if they remained constant it would raise exactly by the amount the ambient did.

As NDB said, the reason why you don't observe an increase in temps is because the fan speed simply increases.

Yeah they do a 980ti one now
Quite tempted tbh. Next weekend I will decide if I want to and which one I want. Would like a Fury X because it's small and quiet though..
I do run 4k, so it's making the choice harder

Was the patronising necessary? I took into account the variables of fan speed, airflow restrictions, quality of TIM, how clean the fins were, components near the GPU and many other variables which are often not equated in testing. I have not seen in my own personal tests a mirroring of temperatures from ambient to core. There are other factors that raise or lower temperatures. Sadly they are not always mentioned. That was my contention. I want to know why Guru3D hit 82°C on a Strix 980ti while TTL's SECOND card only hit 83°C when the delta temperatures were roughly the same. Are these two comparisons not apples to apples? No, obviously they're not. I want to know why. It's not just ambient temperatures like I said. This isn't about what ONE sample of a card will produce. I need to know that all Strix cards can perform the same. I need to see a review where people take all factors into account, not just ambient temperatures.

You can take it that way if you want. However it was just examples. You didn't take into account anything because I wasn't even referring to any of that(excluding fan speed). I stated 1C change in ambient will equal that same 1C change in temps, whether it is lower or higher. You said I was wrong, in fact it is just physics and why some reviewers used to record temps that way to ensure all readings were comparable with the same ambient temp. I gave you examples that reflected that. FYI you don't need to take anything into account really. Most test rigs are identical apart from the GPU. Only different variable is the GPU itself so by isolating the temperature differences in the room, the only factor left subject to change is the GPU.. then they get accurate readings. It makes perfect sense.. helps that it's just how it works anyway. Like I said earlier, the temps will rise exactly the same amount, but due to the nature of the card, the temp increase makes the fan spin faster therefore cooling it more. Even if the temp remains the same, the fan speed increase will make it louder and have to try harder to keep it the same. The fan and core are really the only variables.
75 - 25 = 50
80 - 30 = 55
70 - 20 = 45
u wot mate

Sorry two typos in that example were 55 and 45. It should have been 50 and 50. Just tired when I wrote it, just got home from a 6 hour drive. I will edit the post to reflect the changes.

I didn't say you were wrong. I said it didn't make sense to me and didn't tie in with my own experience. I saw all these other variables. Any more than that I cannot say so I'm just going to leave it at that. I can't prove what I'm saying. I haven't studied physics. I simply find it hard to believe that temperature of the core works that way. It just seems unrealistic to believe that temperatures are that linear.

I didn't say you said I was wrong
I just was informing youTemperature of the core? What?
Temps are just temps^_^Well believe it! Just how it works.. It makes perfect sense. Just think of it like this. The ambient temp of the room is 20C.. therefore the air being sucked into the case is 20C.. which means 20C is coming into contact with the fans which are then throwing that all over the cooler. The GPU is running at 50C with this ambient temp. Now if that ambient temp rose to 30C, the fans are then throwing 30C air all over the cooler. The GPUs temp will reflect this and will read as 60C. It works the other way as well. If the ambient drops, the temp does as well.
You can't just make this happen btw. You would need a controlled environment to test this all out, but since we have physics in the world, we know that this is the case so you can apply this. That's why as I have said, It's valid to record the temp you are getting and then changing the ambient to a set amount of cards. Example would be you test 5 cards and each card was tested under different ambient temps. By making each ambient temp the same(making it the same number), you then apply whatever addition or subtraction you did to each card to their original temp and you have a fair playing field in regards to temps. Hopefully that makes sense. If not well, just look at Delta temps.. that's valid too.

Like I said, I can't prove my point. You repeat the same rudimentary mathematics, but it still doesn't sound right to me. I had no idea that the GPU could heat up so linearly. I always thought there was more to it than ambient temperatures, but whatever. I'll quit 'cause I can't corroborate my points.

You make it seem like its an arguemnt lol
I'm just trying to inform you and teach you something dude^_^

I don't mean to sound like I'm arguing. I simply find it hard to believe that temperatures are that linear. But yes, yes, that's the way they are so just deal with it, Daniel.
