Even with the super-low-RPM case fans, my system runs about 8 degrees C cooler than it did in my old case (an Addtronics 7890A, also common). I've had the SX830 since before they were popular. :-) A much better case compared to the Addtronics. Better quality, better airflow, better ergonomics. I can get into it with zero screws, zero thumbscrews and I don't even need to move it out! :-)
