I am currently playing Rise of the Tomb Raider on the high preset with a GTX 970. It runs at a smooth 60 FPS at a cool temperature. However, after about 10-30 minutes of gameplay, the GPU heats up and the fans start spinning very fast. I turn the game off whenever this happens to prevent overheating, but why does this happen?

Using the MSI Afterburner application, it shows that the GPU never exceeds 69 degrees Celsius, and the fan speeds never get too high, even when the GPU heats up. The CPU temperature never gets too high either. Is Afterburner accurate at all?

Also, whenever the GPU gets heated, the game still runs smoothly.

You can check the fan speeds with Afterburner (or whatever GPU monitoring application you use). See if your fans are running abnormally fast.

Just feeling a warm case isn't going to tell you much. 70c+ of heat being ventilated inside your case is very warm.

Your statements don't match:

"the GPU heats up and the fans start spinning very fast"
"the GPU never exceeds 69 degrees Celsius, and the fan speeds never get too high"

Sounds like everything's fine. Your card is expected to get as high as 80c, per the preset target temperature. Your fans should maybe top out somewhere around 60%. Seems like you're well below on both of those measures. Maybe your MSI Twin Frozr fans are turned off for the first 10-30 minutes and then they kick in as the temperature starts to exceed ~64c? If so, that is how they are designed.

Sorry for not being clear. What I mean is that Afterburner says that the temperature never exceeds 69 degrees Celsius, but the fans spin loud enough for me to hear them, and my computer case feels very warm to touch. I tried lowering the graphical settings (which still look nice, by the way) and the problem still persists. I'll take your word for it, but just incase, what is the worst that could happen if my card overheated? Would it simply shut down, or would my graphics card actually burn out and break?

If it helps, the exact model is an ASUS Strix 4GB GTX 970 OC Edition. According to the box, the fans don't start spinning until necessary. I'm only worried because I don't know exactly how warm my case should feel when the card is heated, nor do I know how loud the fans should be.
