Zalman last year released their reserator 1, a passive cooled water-cooling kit. Recently they released the Reserator 1 Plus package .. pretty much the same stuff, yet with new designed water blocks to get more heat from that precious gear of ours. Passively cooled you ask? Yeah, no fans are involved. No fans people, that means no noise .. yay ! The Zalman Reserator 1 Plus is a fanless water cooling system.
