Suggest heatsink / cooling method for: (hardware details inside)

Hi all. I'm going to be making my first gaming pc in a few weeks or around a month, before that I'm wondering if you guys can help me out.

The specs are:


AMD Phenom II X4 Quad Core 955 CPU- Black Edition (Going to overclock from 3.2ghz to 3.3ghz or around there)

ASUS M4A78-E Mainboard (With integrated graphics and crossfire support, according to ASUS the chip and another card will work together(?) )

G.Skill 4GB Non-ECC Memory, 2x 2GB, PC2-8500 (1066MHz) DDR2, 5-5-5-15 (F2-8500CL5D-4GBPK)

and a Sapphire Radeon HD4890 1GB graphics card (Slightly overclocked) and 750W Power supply.

My question is:

Considering the AMD Phenom is a black edition processor, could someone please suggest a good heatsink, because they don't come with one, and I wouldn't know what to look for.

Also, Would fans be able to cool down this system? or would I need to install a water cooling system? I really wouldn't like to spend another 100-200 dollars (Australian) buying a water cooling system if I can cool it just from fans inside the computer.

Thanks for your time

+1 ^ , but just in case your 955 BE is an oem with no heat sink here's frostytechs best 5 (10) heatsink list. Check the AMD lists there are 2 lists one for best cooling and 1 for quiet. With your modest overclock any would be fine.

Yes, AM2, AM2+ and AM3 use the same HSF attachment.

A couple of suggestions, an AM3 motherboard and DDR3 RAM. Especially since you have an AM3 proc listed.

What I mentioned was just a suggestion, and the EVO got some very good reviews on Hothardware. As did the Gigabyte mATX version.
