ok my 2400 is overclocked at 2.18 ghz. i know i can get it higher but the risk of the core blowing up is increased. the stock heatsink just doesnt cut it anymore. so im trying to decide what to get. im either gonna go with the Swiftech MCX462-V and get a tornado 92mm fan, or get the thermalright SLK-947U with an 80mm tornado when the heatsink becomes available on crazypc. what do you guys suggest i should get? im open to other suggestions too.

The two you have selected will work great for your purpose.

Another recommendation:
This is one that I have for my AMD 2600+ mobile OCed to 2.2 GHz with no temp increase. The fan is very quiet and it is pretty light.

Only issue is this is a huge HS, and if there are any capacitors or other stand offs on the board near the proc, they can get in the way. It is a great one that you will not need to replace any time soon.

Bug

do you think that it will fit on my shuttle an35n motherboard? cause if it will, then i think im gonna get that and save money on buying a heatsink and a seperate fan.
