Already taken the heatsink off and replaced stock *crap* with arctic silver 5.
The fan never seems to speed up. What settings should I have under SMART in the BIOS.
I get min dutcycle PWM (min 20%, may 50%) and I get max dutycycle PWM (min 60%, max 100%). There is also tolerance (1 min, 3 max) and a start temp (which I set to 30 hoping it would keep SMART enabled)
If not I can set to manual with dutycycle 10% min - 100% max...
I would recommend getting a better heat sink. Its only like 30-40$ for a really good one. Im at 4.6GHz with a push/pull configuration on a thermaltake contac 30 with temps at about 69c under full load. Its only 29.99$ here @ newegg. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Then just get another 120mm fan and the grommets for the thermaltake sink and make a push/pull. This will definitely increase cooling coupled with the AS5 that you have. Although if you really want quality, try arctic mx-2.
Under idle load, you should see temps in the 30c area. If you are getting higher than that then something is off, I would investigate if you are using too much voltage on your clock, then testing for stability.
Under max load, you dont want to see temps more than 70c, but 75c maxed out is ok as well.
