My NVIDIA GTX 980 Ti runs at 52-60 C when idling. I was checking the temperatures through the NVIDIA X Server Settings and I'm using the proprietary Nvidia graphics driver. Why does this happen? Is it normal? I get 37 C idle temps on the same computer on Windows. Same fan speeds and all.

What is the critical temperature threshold for the card?

85c

I have a Nvidia GTX 980M on a laptop, and I'm seeing temperatures around 39-44 C when idle. I would expect a desktop card to run slightly cooler, although I can't confirm anything since I only have a laptop. Something you may want to try is to run a different desktop environment, or just run a simple window manager instead and see if it makes a difference.

I was running the full KDE desktop environment, if that helps. And on a desktop.

What driver are you using? You mention the Nvidia X Server settings, so I assume you are using the nvidia driver, but you don't specify which one you are using.
And like I said, trying out a window manager instead of your current desktop environment would at least help you figure out if it has anything to do with it or not.

What does the fan do? Maybe the cooling profile is different on Windows. I'd say we have a look, but the closed source drivers are neither readable in plain text, nor can I find sufficient documentation.

The fan was at 1025rpm, both on Windows and Linux. Linux was at 52-60C while Windows was at 37-40C.

I suggest you try a simple window manager like Openbox. If it's cool there, you will have to prune the KDE effects a bit. They can be hard to assess.

I'm using awesome without compositing and it's idling at 45C. I feel like it could've been cooler...

Did you try the beta drivers?

There are three different versions of the nvidia driver in the repos, I was just wondering which one of these you are using. Since you have a a GTX 980 you should be using the 'nvidia' driver and not one of the legacy drivers (like 'nvidia-340xx').
But if you are on the correct driver for your card, and still running at 45C with just a window manager and no other applications running then I agree that it is a bit high.

I have done some digging in my old notes. It looks like I have encountered this phenomenon in the past, too. Let's summarize the possible reasons:
1. The card runs hotter, because there is more idle workload in X than in Windows. Too bad there is no "task manager" for GPU workload.
2. The energy management is less aggressive in X than in Windows. That means the card does not reduce clock speeds as fast (or as "dynamically").
3. The cooling profile is less aggressive in X than in Windows. That means the fan allows higher temperatures before cooling down the card.
I'd try another way to read the temperature. Try lm-sensors, it should be able to read the card's data. Maybe the config tool is putting stress on the card. If lm-sensors work, try a very minimal setup: xterm directly launched from xinitrc, no WM nothing else. From there it's a loop of reading lm-sensor data and launching windows, comparing the data.
