Unlocked Phenom - cooling question

[Roosti3]

Recently replaced the guts of my 939 with AM3.

ASUS M4A87TD EVO, Athlon2 X3 445, Corsair CMD4GX3M2B1600C8 Dominator 2 x 2gb 1600, Seasonic SS-600HT 600WPSU, P180, AMD heatsink and fan with artic silver

Been running fine for a few weeks so I had a look at the Asus TurboV Evo software that came with the mobo and tried the auto tuning button. Managed 232 Mhz at 15.5x, I know this is pretty poor OC'in practice meddling in windows but thought it was worth a look. Also tried the core unlock function and now I have an AMD phenom II X4 at 3.6GHz.

This is great news but just wondering if I should be running this at 3.6GHz on the stock AMD heatsink and fan?

while surfing I am at 35 degC (30degC on sleep mode). Tried using the stability test on the AMD OverDrive software to fire up all 4 cores and it hit 61 degC within 2 minutes and was still rising so i decided to stop. Playing "world in conflict" (2007 spec RTS game) it is stable at 54 degC.

I don't want to damage anything so at the moment so I have reverted back to 3.1Ghz at X4 and the stability test temperature stabilises at 58 degC after ten minutes.

So do I need a aftermarket fan? I have 75 degC noted as the max temperature for the CPU but at what temperature should I be aiming to operate at?

Usage realisticly is surfing probably 70% of its life with the rest office applications and medium spec gaming.

The AMD Overdrive test doesn't do a very good job of heating up the CPU. You should run the multi-core version of Prime95 with the middle option (in-place) to see how hot your CPU can get. You will want to stay below 60C at all times.

If you got to 61 C in only two minutes then you will definitely want an aftermarket cooler if you are going to be running the cpu at that speed permanently. Even though 75 C is the noted max, you don't really want to be getting near there. Nice job unlocking that extra core though.
