    Product Description

    The MAG series was born through rigorous quality testing and designed to be a symbol of sturdiness and durability. Focused on providing the best user experience, the MAG series has a simple installation process coupled with a friendly user interface making it the best choice for entry level gamers. The newly introduced MAG CORELIQUID Series has everything you're looking for in a liquid cooler, ranging from quality materials that provide reliable durability to heat dissipation technologies that are extremely effective. Users can even enjoy perks like ARGB lighting and a 270-degree rotating blockhead that is simple to use. On top of that, the blockhead boasts a unique irregular aesthetic that is both stylish and artistic. Every single component of the MAG CORELIQUID Series is designed with the end goal in mind: to provide effective cooling without any compromise. Mount the cold plate at any orientation, turn the blockhead up to 270 degrees, and keep it upright.The pump has been integrated into the radiator for sound dampening and noise reduction. Additionally, placing the pump into the radiator also increases the pump's life expectancy by moving it away from the heat source. A durable three phase motor at the core of the pump generates minimal vibrations for long-lasting operation. A split pathway through the radiator rapidly dissipates heat, cooled liquid is then pumped back into the loop. Constructed with three layers of netted plastic tubing and a reinforced mesh exterior.
