The CAK 38 is clearly one of Global Win's high-end models. The manufacturer has come up with a good combination: a high-speed fan that rotates at 6000 RPM and a heat sink made of pure copper ensure that cooling performance is a very good 38 degrees. However, this high performance comes with a price - a high sound level of 59 dB. This is sure to set the cooler up for some run-ins with trade unions and professional associations. Weighing in at 488 grams, this is the heaviest cooler among the newcomers.
