My question is, what is the best oc'd performance I could get out of it with this cooler: http://www.newegg.com/Product/Product.aspx?Item=N82E16835103064
Or with this cooler:http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065
I would go for the Hyper 212 as it has the bigger fan and also the heatpipes are not in a direct line for airflow. Having the heatpipes staggered in a air cooler does allow for better cooling. The only thing I would say if you have high profile ram you might want to check that the Hyper 212 won't cause an issue by covering a ram slot or 2.
For the A10 I generally recommned the TX3, simply because if you are using the A10 then you're likley on a strict budget and that fan performs really well for its price, though I usually pick it up for around $18. The 212 is the better cooler though, theTX3 is considered to be the 212's little brother. I suggest the 212 for the FX6300.
I believe there are three coolers in this family btw, the 101 (80mm), the TX3(92mm) and the 212(120mm).
