Is the new Thermalright SLK-600. Looks like the SK6's big brother. This sink makes a 60mm fan look small - it's that big. This sink is for the Socket 370/462 motherboards . Also a 80mm version is coming in June called "SLK-800". Plus a new P4 sink, 80mm also, SLK-478 coming in July. Read more for info and link. Just found a review also. The temps are looking good!
