Help with HSF's

[Settyboy]

I'm building a Dual AMD system (Tyan S2460 with 1.2 MP's) next week. Being that the MP's are oem I need to pick some HSF's. I'm not interested in OC'ing the procs but I will be doing alot of heavy 3d rendering so I'm looking for better than average cooling. Noise is also a big consideration since my last dual proc system drove me insane with how loud it was. I was looking at the ThermalTake Copper Orb and the Agilent Artic Cooler CA as possible choices. My case is modded with a window so I thought the round sinks would look best. Any experience with which one works better and which would be most quiet? Also, is there any others I should consider? I'm looking in the sub $25US range if possible. Thanks

Settyboy**** I am using several all copper hsf's. Favorite is the Golden-Gate with the quiet 30cfm fan,(which is on by default). It is square in size. Easy to install with an unsharpened wooden pensil. It is the same fan as the ocz gladiator, except their's is higher. Think they cost about $20 with shipping. USA.
http://www.svcompucycle.com (ocz is overclockerz.com), I think. Excellent cooper coolers. Value too.
