The CPU temps of my Athlon 2700+ is running about 10 deg C higher than the\n1800+ ran, 52 vs 42 at a room temperature in the high 70s. I have also gone\nfrom a fanless ATI 9250 to a fan-equipped ATI 9600XT and from a fanless to a\nfan-equipped northbridge heatsink. The case temp now runs 40-43 and the CPU\ntemp 11-12 deg higher. Heatsink is an all copper unit and hasn't changed.\nThe tower case has in inlet fan in front and exhaust fan in rear buy I know\nthat the vents in the front of the case impede airflow (I pulled the front\noff and the CPU temp dropped 3-4 deg C).\n\nQuestions: does a 52 deg C CPU temp seem high? The computer is on about 10\nhrs per day.
