i need good air cooling

[thefish]

basically i have an x2 3800 that i want to air cool and a dfi ultra-d motherboard but am unsure as to what will fit in my motherboard and what one would be the best performer

I would personally say the Zalman 9500.

I had exactly the same cpu+mobo setup under one and at stock speeds it idled at 30 and never went above 35.
When overclocked to 2.6GHz (@1.45v) temps never went much past 40.

It also keeps my current chip (oppy170) under 50 degrees at 2.GHz on 1.55v
