DFI cooler that attracted a lot of attention is actually no mystery at all. The twin tower cooler comes from a rather unknown and new Taiwanees company called Prolimatech and it's actually already available and selling for €59,90 in Europe.
The heatsink itself has six, 6mm heatpipes running through two aluminum fin towers. According to the product page, the wide fins have mathematically calculated thickness to give best air to surface cooling rate. It supports socket 775 and 1366 processors. It doesn't come with a fan, but Prolimatech suggests 120mm fan that spins from 800 to 1200RPM with a 57CFM of airflow.
As the heatsink itself is already available and selling here
, and our guess is that DFI will probably bundle it with some high-end motherboard rather than get into cooler business. You can find the Prolimatech site here, and you can find the DFI branded picture as well as some original pictures of this heatsink below.
