🔍 Summary Table

🧠 Real-World Insights

• Non-PoE models are truly fanless and nearly silent—great for noise-sensitive environments
• Pro models with PoE include fans but are reported to be “near-silent” in typical deployments .
• Consider the port speed, PoE needs, and routing requirements—Pro models add Layer 3 capabilities and higher bandwidth.
