Please do not run any processor of any type without any form of thermal paste on the top of the processor.
Also do not run it without any form of active cooling, otherwise you run the risk of the processor cooking itself.
With regards to the overclockability of something, if you buy a processor there is no guarantee you will be able to overclock it. Due to the way processors and silicon chips are made, a lot of them end up as effectively repackaged lower models.
The most obvious example is probably the Sempron 140, AM3 AMD processor. It is a cut-down dual-core Athlon II X2 440 processor because one of the cores on the chip sold as a 140 is defective, most likely. Therefore as AMD will not sell a faulty dual-core processor they simply disable the faulty core and sell it as a Sempron 140. This also cuts down on waste at AMD's end. Out of a total of around 1000 processors made for the top-range of that batch two thirds of them typically end up being cut-down in some way due to faults that occur in the manufacturing process. It is much better to sell them in some form rather than throw them in the bin. Some will end up being scrapped.
So to cut a long story short: Just because your board will overclock doesn't mean the processor will. You have no way of knowing whether your processor will overclock until you try it. This applies to AMD and Intel processors.
