Re: Overclocking E6300 browser shuts down Part 2
Personally I get nervous at 50c and above. My E4600 is dead on 3ghz using an Ultima 90 heatsink and a silent Zalman 92mm fan, and maxes out at 44c.
Others here may feel differently, but 50c is my max even though more is safe. Depending on the airflow in your case, all you may need is a better fan setup.
Can you post a pic of your case with the side open? Better cooling may be easier than you're thinking.
EDIT: From what I can see, I think you are right about the max temp for that proc.
