Akasa
Cooler manufacturer Akasa had this pretty heatsink on display which is made from several sheets of different colored anodized aluminum. Very pretty.
As advanced cooling concept they had the REVO 92 CPU cooler on display. It is a self contained liquid cooler which uses a "bubble pump", whatever that is, to move a liquid inside aluminum tubing. According to Akasa this design can transport more heat than a traditional heatpipe because there is no mix between gas and liquid.
