Newb here. I just built my first computer ever about 2 weeks ago. All the parts are new. Every time I start playing a game, no matter the settings, my Asus GTX 550 ti plateaus at 95c and the fans are at 100%. Nothing really happens at the high temperature, except on AC Revalations (I don't have that many games, and desperately need more) the FPS dips into the 20's.
Air needs to flow from one direction to the other. Most people like for it to flow from bottom/front to upper/back. some fans are useless as far a determining which direction they blow. If it is, test your fan directions by loosly a paper towel or a klennex close to the fan. I know this sounds crazy but sometimes using your hand to feel which direction it blowing sometimes fakes you out.
Also make sure that nothing is blocking airflow out the back.
Guys, everything seems to be working okay now. I removed the drive cage in front of the front fan and consequently some of the cables. Now the GPU temps are around 50c. The first suggestions were great. Thanks all.
