which cpu cooling system will be the best for x3450 (like I7-860)

[liverpool4ever]

I am planning to OC it approx. by 50% (from 2.66GHz to 4)

Since the "regular" power consumption of this cpu is around 90Whatts I will be needing a monster...

If anyone is familiar of any cooler which will be good for my purpose - please come forward.

Can you overclock Xeons?

Assuming your board and CPU will allow you to do that:

Some quick suggestions (may not be the best in their price category but at least will get the ball rolling)

Low End - Hyper212 Evo
Mid Grade - Noctua U12S
Upper End - Noctua NH D14/15

Important to check your case and motherboard compatibility with the cooler's height too, as well as the clearance with the RAM slots and the PCIE slot.
