Title pretty much explains the issue. I'll admit I neglected properly dusting and maintaining the GPU for well over a year, so of course my 1st assumption was that my GPU was simply caked with dust. This was true, so I removed it and thoroughly cleaned it.

Previous to cleaning: idling at 39C/reaching 70+ playing just rocket league/95+ attempting fallout 4.

After cleaning: idles at 32C (still 5-6 degrees higher than room temp/my CPU cores - presumably not normal?), still soars into the 90's upon trying Fallout 4. FO4 also puts the card under 99% load, unsure if that's the norm or not.

I can't say my case has the best air flow, but it's also open. I use a bulky aftermarket CPU cooling fan that only leaves ~1 inch between the bottom of it and the top of my GPU. I notice if I put my hand between there, the air flow in that area is much warmer than anywhere else in the case. Could this big object be obstructing the air flow for the GPU?

Any thoughts on why this thing is getting so hot? Do I need to clean it better? Should I re-arrange some case fans? Why would it idle at higher than room temp? It doesn't seem like this is an airflow issue, since the temperatures soar upwards almost instantly when I enter a game. Strangely, I don't see noticeable strain on the card while playing, and stay at a constant 60 FPS in Fallout4. I never would have known the card got so hot if I hadn't checked for curiosity's sake.

I should start charging every time I explain how Turbo Boost works. Your card, every GTX 770 by default, has a Temp Limit of 80c. You can check and confirm this in Afterburner or PrecisionX. What that means is that your GPU was designed to target exactly 80c as its normal operating temperature while gaming. Above that temp your card will lower its Turbo Boost clocks, decrease voltage, and increase the fan speed to maintain and stay at 80c. Below that temp and your card will ramp up more with higher Turbo Boost clocks, increased voltage, and lower fan speeds.

Note the Temp Limit is part of the...

Note the Temp Limit is part of the overclocking/Turbo Boost parameters that can be manipulated through Afterburner/PrecisionX; it is NOT the same as the thermal threshold, 98c, the point at which your GPU is risking damage.

So 80c is normal and expected...... on a reference card. Now, many people have been spoiled by their custom cards with nice cooling and high airflow cases. They rarely, if ever, see 80c on their GPU, but that is still the Temp Target for Turbo Boosts. Now, it is summer and apparently Planetside 2 is one of those games that'll push your card to operate at 99% GPU usage, so a higher temperature is to be expected.

We need to dispel the myth that 80c is alarmingly high, when in fact it is exactly the temperature at which the GPU was designed to operate.
