The Taiwan-headquartered GlacialTech Inc. is known for its affordable but effective CPU coolers in the first place. The Igloo series has earned a good reputation in the entry-level sector due to a lucky mix of two important factors: price and performance (read – efficiency). GlacialTech also offers a premium product called UFO V51 but this cooler has not yet gained much recognition among overclockers. Right now, the company is making a second attempt to roll out a high-performance air cooler capable of competing with the best opponents. I mean the new F101 model (or even two versions of it with different fans). I’ve got a sample to test and will focus on it in this review. Additionally, I will take a look at anIgloo 5710 Plus Silent which represents the current stage of the Igloo 5710 series.
