Why does serial AT keeps compuyuter cooler that parallel ATA?

Temperature is a critical factor impacting the reliability of drives and other components-the cooler the drives, the greater the reliability. As enclosure manufacturers develop solutions based on these ultra high-density drives, it is critical to ensure proper cooling and fan redundancy to preserve system availability. SATA is well-positioned to handle these environments since its thinner cabling allows better airflow through the system. Answered by jefferson.
