Questions about this item
Does the 280 W power supply have a replaceable fan or internal filter that needs cleaning?
The dock has no user-serviceable fan or filter; keep the vents clear of dust for reliable cooling.
Which limit appears first when driving four 3840 x 2160 displays all day — the 280 W budget or Thunderbolt bandwidth?
Thunderbolt 4 bandwidth is the first constraint; the 280 W supply handles the dock and typical laptop charging within its rating.
How loud and hot does the unit get after eight hours at full 280 W load?
It runs silently with no audible fan; the aluminium chassis stays warm but within normal operating temperature.
