I highly recommend that you watch your Video Card Temperature while playing SC2 for the first few weeks. New games, bad drivers, inadequate ventilation and slow fans have been known to cause problems in the past!!
Keep your drivers updated, and keep an eye on your FPS.
You can do this by pressing Cntl+Alt+F while in game.
I have a GTX260 Gigabyte- which was rendering the game- and the opening Cinematic at over 300 FPS. Obviously, this is unnecessary and potentially dangerous.
This concerned me. As, my card usually runs at 59c when playing a game reasonably loaded (WoW or SC2 Beta)... and rarely gets to 60c or above.
Today, after 10 minutes it was up to 65c. So I shut down and dug up this old thread by R1CH. (The Master of the Universe) This is a trick to CAP your CPU and Graphics Card usage, which may run unnecessarily high:
If you want to reduce CPU usage, you can edit your Variables.txt in My Documents / Starcraft II and add the line "frameratecap=60". This also reduces CPU usage as well as GPU usage, contrary to how I thought it worked.

Apparently it still works just like in beta.
My Temperature is running normal now, rendering at 60 fps, and I am very happy.
Thank you R1CH!!!!!
Hope this helps someone else!! Be careful out there and have fun guys <3
TL:DR Do the instructions in the Quoted text above to limit your FPS in game and reduce the load SC2 puts on your system.
Edit: Apparently V-sync under the graphic's option will limit it to your monitors rate. IMO- still monitor your FPS and cap it anyways.

Thank you for the reminder. I have had the windows open in my house but I noticed that beneath my desk was extremely hot when I was playing last night, and it was plenty cold outside. Turns out it's been a dusty few weeks since I last cleaned my case out and my video card was definitely not lovin' it. Losing your hardware due to poor maintenance (drivers, fouled heatsinks, or god forbid loose or dried out thermal contacts) will NOT leave you with a good feeling inside.
Also: In many cultures, the term "v-card" has a VERY different meaning than you intended, which was what got me to open this thread. "What the fuck is a v-card temp?" -_-

I thought Blizzard already puts a cap on FPS... guess not.

Thanks for this help. I've been having a lot of temperature issues with the full game (no problems whatsoever with beta)... I'd definitely advise everyone to be careful!

I had no idea. Mod's of course can change it if they want. (In retrospect, "GPU Temps!" would have been a much better Title.)
My only concern was to have the whole message get across as best as possible in the little space.
And, ya, at least from my observation, without the edit SC2 is pretty much going to max the crap out of your system no matter your settings. The real benefit from reducing your Graphics settings will really only manifest after you cap the frame rate. Or its just going to proceed to render the lesser graphics at more speed.

If you use vertical sync then it will cap it to some obscure framerate like 40.

I had a very similar problem. I found that I could only play the game for a few minutes before it started to sloooowww to a crawl. Rebooting helped, but only for a little while. As it turns out my GPU was at 100 degrees! I let it cool down and took out a sound card that was blocking air flow, and now it's doing well. I've played games for several hours before and never observed temperatures above 70. I guess sc2 works out some parts of the card that were untouched before. I'm just glad it wasn't damaged.

Yeah, SC2 has always turned my dual 5850's into a freaking space-heater.
However, turning on VSync in the options should cap the framerate

I would have left it at this, though I was affraid that "a fraction of my Monitor's refresh rate" could also mean 2/1 or 3/1!!!
... aka 120 or 180.... just to be safe I wanted to cap it too.
Thanks Manifesto7

Reduce the load? why would anyone want to do that?
Use manual fan speed
use manual fan speed
USE MANUAL FAN SPEED
USE MANUAL FAN SPEED
I cannot begin to tell you the number of problems that result from auto fan speeds. You shouldn't need to hobble you GPU at all. Hell you have a faster card than I do, you should be running ultra HD like I do, no some pussy 60 fps, no offense.

pussy 60 fps? You do realize that is quite a bit more than humans eye can register. In other words there is no need to play the game on 120 fps if you can play it on 60.

lol Okay?
I don't want my card running over 60c if I can help it.
I really can't tell the difference between 60fps and 200fps.
Also... The textures on Med/High where I have them now are fine.
My fan is always at 100%. The card came like that.

Framerate cap isn't in variables.txt anymore, so your suggestion doesn't apply. Unless someone found it.

Forget about eyes. Monitors can only draw so many frames per second. FPS higher than 60 are usually used for benchmarking.

I have an LCD, it can only display at 60fps. Why not cap it to that rate? Any higher and it would display tearing, which I HATE. I love the smoothness of vsync

Oh really? Thanks. It was posted on the boosting fps guide as missing. Might wanna go post in that thread too.

Lol doesn't sound like OP has ever used 4x or 8x AA and maxed AF for his 260. You will be heating that GPU in no time. And agree - change your fan profile with Afterburner.

gonna give vsync a try
my laptop is running HOT
