You are correct fats.

That is 0.23C/W using the <A HREF="http://www.deltaww.com/products/dcfans/pdf/AFB8080254.pdf" target="_new">Delta Electronics AFB0812SH-F00</A>. That is a 80mm^2 x 25.4mm, 40 dBA, 80 gram, 46.6 CFM or 1.32mm^3/min fan. Not like that dual bladed fan on the <A HREF="http://www.swiftnets.com/products/mcx462.asp" target="_new">Swiftech MCX462-U</A> which uses the <A HREF="http://www.deltaww.com/products/dcfans/pdf/FFB808038.pdf" target="_new">FFB0812SHE-F00</A>. (One loud and powerful beast.)
You can use a lower dBA and CFM 80mm fan and still get great results. Using the <A HREF="http://sanyodb.colle.co.jp/product_db_e/coolingfan/dcfan/dc_fan_detail.php?master_id=59" target="_new">Sanyo Denki 109P0812H702</A>, which is a 12V, 80mm^2 x 15mm, 68 gram, 31 dBA, 32.16 CFM fan, it achieved a 0.26C/W.
Many of you know that I have always been biased towards the Alpha over the Swiftech the results prove themselves here. It is a great cooling solution for P4.
