Drive Heat and Usage Differences: EXOS vs. IronWolf
Seagate EXOS Drives:
Enterprise Design: EXOS drives are designed for data centers and enterprise environments. They are built to handle high workloads, with features that prioritize performance and durability. However, they typically generate more heat and are noisier than NAS drives because they are optimized for environments with robust cooling systems and constant, high-speed airflow.
Heat Generation: The temperatures you're seeing (60-64°C) are high for a home NAS, especially with no load. While EXOS drives can technically operate at these temperatures, prolonged exposure to high heat can shorten their lifespan and reduce reliability. They're meant to be in rack-mounted servers with excellent cooling, which might not be ideal for your Jonsbo N4 setup.
Seagate IronWolf NAS Drives:
NAS Design: IronWolf drives are specifically designed for NAS use in home and small office environments. They run cooler and quieter than EXOS drives, making them better suited for home setups. These drives have features like vibration management and power management, which help them operate efficiently in less harsh conditions.
Lower Heat Output: IronWolf drives tend to run cooler, especially when paired with efficient cooling. The temperatures you mentioned (around 35°C) with the Noctua fan are ideal and well within safe operating limits, even under load. They’re designed to work well with NAS cooling systems and quieter fan setups.
Options Moving Forward
Switch to IronWolf Drives:
Better Suitability: Given your concerns about heat and noise, IronWolf drives are likely a better fit for your setup. They are designed to run cooler and more quietly, which means less reliance on high-output fans.
Longevity and Reliability: Operating at lower temperatures will help ensure the longevity of your drives and reduce the risk of failure. IronWolf drives are also designed to handle NAS workloads, including RAID configurations and continuous operation.
Fan Management and Cooling:
PWM Fan Control: Since your motherboard lacks PWM support, consider using a fan controller that can manage fan speeds based on temperature. This can help reduce noise while still providing adequate cooling.
Fan Configuration: Keep the Noctua NF-A12x25 fan for its excellent airflow and quiet operation. Even at lower speeds, it can provide sufficient cooling for IronWolf drives, ensuring your NAS remains cool and quiet.
Adjusting Fan Speed: If you stick with the Noctua fan, lowering its speed to reduce noise is viable if using cooler-running drives like IronWolf.
Consider Returning the EXOS Drives:
If you can easily return the EXOS drives, it might be a good idea. They are overkill for most home NAS setups and require conditions that are hard to maintain in non-enterprise environments. Sticking with NAS-optimized drives will provide a better balance between performance, noise, and cooling requirements.
