knightfightx :
Thank you. So i wont need a new PSU then.
Well, i have 1 fan rear fan, back of the case, and i think it is blowing air into the computer starting to flow over my GPU towards the hard disks. Doesnt this fan need to blow air outside instead to the inside? If so, how do i make this happen ?
I also need to buy a second fan for the front side of my case, the place right under my hard disks. When i buy that, and fix the rear fan, if there is something to fix, will the temperature drop ? Im afraid to start my games like dues ex human revolution because the GPU temperature raises from 40 to 60+ degrees when i only play counterstrike. So i think my GPU will be overheated when i start a game that is way heavier then counterstrike.
Thank you.

Make sure you run CS with Vsync.
Even a very basic game can bring a GPU to 100% utilization if Vsync is disabled and the game doesn't have a framerate cap. Vsync causes your framerate to be capped at your monitors refresh rate (typically 60Hz), it can eliminate some graphical glitchiness, but if you're not at 60FPS you'll likely be at 45 or 30 (because you only use frames that are done when the monitor refreshes).
My guess would be that you are running CS alot more than 60FPS (because of no vsync), and because the temps are high you think it's taxing the GPU, but in reality it's handling the game fine, but you're running full throttle with no brakes. It may be that more challenging games actually heat up your components less..
You should turn your rear case fan around so it blows outward. Just unscrew the 4 screws in the corners of the fan, flip it over, and screw it back in (The screws take a bit of turning force to go in because they are actually cutting through the plastic of the fan to make threads). It's certainly not a bad idea to put a fan on the front blowing in; usually case fans have 2 arrows around the outside edge, one shows the direction the fan rotates, the other shows the direction the air moves, use those to get it the right direction.
Edit:
Another note: Typically, a desktop GPU is designed such that it cannot fry itself just because you're settings are too high (not always, it's good to be dilligent, also laptops are another story, be careful with them
), if you get a GPU monitoring program (sorry, I don't know any good ones, I use the one that came with my gpu) you'll see it hit highs and lows, and often isn't staying at 100%. Often times it's only badly programmed games (or simple one's with no framerate capping) that will keep the GPU at 100%. Legends of Grimrock, an indy-retro-style dungeon crawler will bring my 7870 to 100%, running 500FPS...
After upgrading my wife's PC to a 7770, we learned the Sims 3 has an internal framerate cap of 30FPS, but it lets the GPU render at any speed, so once you get to 30 FPS, it renders the same scene over and over as fast as it can, hitting something like 180FPS for her. The game destroys laptops... (one more reason to hate EA, since they don't seem to care about fixing it, you have to get a 3rd party program to keep it running reasonably).
