The operating temperature of the Thunderbolt 4 Dock ranges from 86°F to 131°F (30°C to 55°C).

It is normal for the Thunderbolt 4 Dock to feel warm, and at times hot, to the touch while it is in use. The dock has a large aluminum body that spreads heat away from the internal components and connected devices, so the warmth you feel on the surface is the dock working as designed. It is not a sign of a fault and will not affect performance or damage the hardware.

The Thunderbolt 4 Dock is built to the IEC 62368-1 safety standard (the international safety standard for audio, video, and information technology equipment), so this surface warmth is expected and safe.

To help it run cooler:

• Place the dock on a hard, flat, open surface.
• Keep the area around it clear so air can move freely.
• Avoid enclosed spaces like a closed drawer or a tight shelf.
