After a period of insanity where fan speeds were hitting the 7000RPM range, there was a clamor for quieter fans as many end users decided that an absurd amount of noise was no longer an acceptable trade off for performance. Zalman was one of the first companies that embraced this philosophy with novell heatsink designs some passive, some with low noise fans. A few months ago we took a look at what was the biggest heatsink we had seen at the time with the Zalman CNPS7000A-Cu. As far as width goes, it simply dwarfed every other heatsink we have run across in our lab. Today, our eyes have been opened much like Cortez as he spied the Pacific for the first time. Zalman trumps the CNPS7000 with something even bigger, the AlCu 7700.
