Earlier this year we took a look at Iceberg Thermal’s IceSLEET X7 Dual CPU Cooler, which was part of the company’s first round of products as they were just entering the market. We thought the cooler was interesting, had decent performance, but all of the plastic on it made installing a little annoying. Well Iceberg Thermal is back with their second round of coolers and today we are checking out the IceSLEET G4 Midnight, which happens to be a limited edition all-black cooler with an RGB fan. The cooler features a single-fan, single tower design with four heatpipes and is able to handle thermal loads up to 180W. Has Iceberg Thermal made improvements over their first generation of coolers?
