50c is a little too high at idle for that cpu. You want to keep temps under 60c at full load and at that rate you'll fly past that especially if you overclock. get a nice aftermarket cooler or clean out the dust from your case before you seriously consider overclocking. That being said i pushed my old E8400 to about 3.8ghz on a stock cooler and would get to about 60c at full load. Should be no problem for you to push it there or even further.
Yes hello again, so I bought a new cooler for my CPU a Arctic freezer 13. Now the cpu runs at about 35-40 at idle and during prime95 stress test at about 58 degrees both cores. What does concern me is that during the torture test i could not hear any increase in the cpu heatsinks fan speed.
My cooling solution is air. one small fan sucking air in front and a bigger one (12cm) at the back blowing out. Only problem is my case is pretty small and when I have a "big" graphics card in there and the arctic freezer there is little room for air to flow.
How much would you recommend I would overclock it? And what program should I use?
