Safe Overclocking & CPU Fan's

[iknowreal]

This is my CPU CPU: AMD FX-8350 Vishera 4.0GHz (4.2GHz Turbo)

This is the CPU cooler I was going to buy

http://www.newegg.com/Product/Product.aspx?Item=N82E16835103099

Now Its sold out... what do I do? What are my options. I only want to go better or same performance.

How high can I safely overclock it.
