i actually undervolteded it, its running at 1.12v and max at 1.14v i'm using CPUID HW Monitor and AIDA64 and yes i got 56c in prime95 but nothing ever stresses a computer out like that realistically lol
alright, i only got a gtx 460 so no reason for higher lolz, if i ever find a game i can't get 40-50 fps in i'm gonna upgrade cpu XD maybe gpu, but hopefully not for 1-3yrs i only play WoW and cod anyway
Personally I think that since it is stable and at a good speed
leave it alone
An extra 400 mhz or so doesnt really make any difference other
than in synthetic benches
If OCing for the challenge of it and good benches are your hobby
then go for it
for real world applications it really wont make much difference
Though having a C2D at 4.0ghz is a cool thing to brag about LOL
Don't be surprised. It's a 65watt chip and a dual core to boot. Doesn't take much of a heat sink to keep that cool. Even at high OC's.
Now 95watt chips, MIGHT need an aftermarket cooler.....
But get into the 125watt and 130watt CPUs, and the stock coolers won't even support Stock speeds and voltages let alone an OC... (example: i7-900 series, run Prime95 and watch the temps soar with a stock cooler. Even aftermarkets struggle when your shooting for 4Ghz... and <80C)
