Cpu longevity

if you have good cooling than it shouldnt effect it to much but will decrease the lifespan of it if your running with higher voltage than recommend, but as long as u have a good cooler and temps are good u should be fine.

^agreed
what core temps are you at?

I have never run my now aging b3 q6600 at stock frequency/voltage. Well I did to install windows but... two years plus, and i haven't noticed any problems what so ever. Over clock that f-cker and enjoy, just keep your voltage under 1.35 and core temps under 70c.

lol thats the spirit

im not 100% sure, but on speed fan it says cpu 32degrees, and core 0 and 1 are 39 degrees. after prime95 it gets to 70 or so

Have you thought about investing in a third party cooler?

I upgrade my CPU every 6-8 months, this is well before the CPU will die

im thinking of getting the cooler master tx3, that should help lower temps a bit
