I built this computer myself about 4 weeks ago. I don't do any Overclocking and in the bios it is set on Normal mode. Yesterday my computer hit 70 C from playing a video game all day. Turned it off immediately. Today I turned it on and went into bios. It started off at 40 and went to 60 in about 3 mins. I do live in Arizona and its the hottest time of the year if that matters. (115 F daily) I have a Cool master HAF which is suppose to have great airflow. Im still using the stock fans and I am thinking that i need to upgrade to aftermarket. From what I have read I should be in the 30s to low 40s. One thing I could see the cables from my Power supply possibly blocking airflow from the front fan. Any suggestions.
Here is the specs to my computer.
1024MB GDDR5 GeForce GTX550Ti SC

Also, a bottom mount Psu shouldn't interfere with air flow. The mess of unused cables might, however. Tie down/back any cables that could be blocking air flow. The HAF 922 with its 200mm fans and the 120mm should be plenty for cooling under normal conditions.
Did you build this yourself? Is the Intel cooler on correctly? Check the 4 push pin feet that they are firmly flat against the motherboard and not up slightly. That would indicate the an improper assembly. The heat sync must be making firm contact with the CPU's heat spreader to transfer heat properly. Look behind the board to be sure the white posts are opened and 'latched' behind the board.
