Any Recommended Passive AM2 Heatsinks for use in a Slim-Case?

[CKTurbo128]

Does anyone know of a good AM2-compatible, passive heatsink for use on a A64 X2 BE-2350? I have a Media PC setup that is currently a little bit too loud and I'm trying to reduce the noise output. It has to be able to fit in a slim-case. I have also undervolted the BE-2350 (to reduce power consumption) and is running cooler than it does at stock.

Does anyone have any suggestions?

About your only choice would be to work on something like bonzai duck uses. A large heatsink (A 2U copper heatsink is probably your best bet, can't recommend much since you haven't said what your case is). Then fashion a cardboard duct firmly around the heatsink with a decent gap at the bottom of the heatsink for air to come in. Direct that shroud to one of the case fans and apply some sort of sealing agent around it to ensure that all air pulled through the fan is pulled through the heatsink.

Can your case take regular video cards, or only low profile?

I'm using a passive Scythe Mini Ninja in my HTPC with an Antec NSK2480 case, but of course that case is ventilated by dual 120mm fans.

I'd highly recommend you running a quiet and undervolted fan on the CPU versus trying to run it passive. Even the lowest amount of force airflow is vastly (we're talking 1000% better) superior to passive cooling of comparible size.

Do you have Smart Fan control in your BIOS? Some BIOSes do not, and some do, but can only control 4 pin CPU fans (if yours is 3 pin).
