The extra large aluminum alloy heatsinks take away heat dramatically. As the MOSFETs & chipsets areas are well covered by these heatsinks to protect them from overheating, CPU & chipsets can perform with lower temperature, & your motherboard & system will be more stable & reliable. The Nex FET MOSFETs control the power supply to DRAM slots more efficiently. They provide lower RDS (on) 2.9 m O, delivering higher efficiency & lower temperature.
