THERMAL SOLUTION FOR MORE CORES AND HIGHER PERFORMANCE With more cores’ processors, thermal and power design is more important to make sure the temperature keeps lower. MSI extended PWM heatsink and enhanced circuit design ensures even high-end Intel CPU to run in full speed with MSI motherboards. FULLY CONTROLLABLE IN BIOS AND SOFTWARE MSI motherboards let you manage speeds and temperatures for all your system and CPU fans. Total Fan Control allows you check your primary system characteristics in a simplified graphical interface. You can also set up to 4 temperature targets for CPU and motherboard, which will adjust the fan speeds automatically. M.2 SHIELD FROZR World’s fastest SSDs can start to lower performance when getting hot. Part of the motherboards heatsink design, M.2 SHIELD FROZR is the next generation M.2 thermal solution to avoid this by offering the best thermal protection to make sure that SSD maintains maximum performance. FROZR AI COOLING Detecting CPU & GPU temperatures and automatically adjusting fan duty of system fans to a proper value by adopting MSI AI ENGINE. OPTIMIZED FOR WATER COOLING Designed to support the most popular All-In-One & customized water cooling solutions on the market. A dedicated water pump PIN header supports up to 3 amp, giving you full control of the water pump speed. A clearly marked ‘keep-out-zone’ allows for easy and safe installation and a perfect fit. LIGHTNING GEN 4 M.2 Utilizing 12th Gen Intel Core processors, MSI B660 motherboards feature latest Lightning Gen 4 M.2 which is the fastest onboard storage solution on the market with up to 64 Gb/s transfer speed.
