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, MOSFET & chipsets can perform with lower temperature, & your motherboard & system will be more stable & reliable. Specially designed for memory power delivery, the alloy chokes feature a highly magnetic & heat resistant design, thus delivering more stable & reliable power to the motherboard. ASRock does not overlook any details, even those tiny ones. With PCB appearance, the Sapphire PCB represents rock-solid quality & gives the motherboard a more mysterious touch.
