After pulling out the T7 Torx screws, we meet Apple TV's biggest fan!

It looks like Apple merged the new fan with the heat sink/EMI shield assembly from the Apple TV 4th Generation—combining them to form one whopper of a cooling solution.

This Voltron of a thermal assembly suggests that 4K HDR capability comes with a significant increase in thermal output.

With the twist of a few more Torx screws, the assembly is disassembled—revealing a replaceable fan driven by a Nidec brushless motor.

A replaceable fan is good news for owners. Otherwise, we're guessing that a failed fan would quickly mean a failed device.

This new fan assembly is apparently secured by an identity disk. TRON, is that you?
