Looking for a good cpu heatsink for overclocking,.

[Reprisal]

AMD Phenom II x6 processor, something quite and not horribly expensive. Any suggestions/favorites out there?

The ThermalRight Ultra-120 is what I've been using the last couple of years on my CPUs. Very efficient so far and do a superb job.

[edit] Worth noting that you can use any good 120mm fan on it. I used a Scythe ultra-quiet model and have had great performance with it.

Go for 2 120mm fans:

It cools better because it's louder, AMIRITE?

+1 for the TRUE. Just get the standard version, don't worry about the 2kg hunk o copper, esp. if you are mounting it on a vertical motherboard. I used this for a couple of years before switching to a silent liquid setup. Not sure about the AMD chips, but this is a really well recgnised cooler for getting i7 920 chips to 4GHz without problems.

+1 For the TRUE as well from my corner. Also, the push/pull setup of 2 fans will not "double" your cooling power, it may not even have any real effect on your setup at all. I have nothing to back up this statement except for my good looks.

I picked up a Corsair H50 liquid cooling unit for my alternate rig a few months back. It keeps very stable temps for a Q6600 @ 3.6GHz below 60*C. Cant remember how much exactly though.
And the unit is completely self contained, no maintenance reqd.
I haven't tried changing the fan yet (alt box and all), but I imagine a decent yate loon or similar fan would do better still.
