Questions about this item

What is the first thermal limit reached by the heatsink fan assembly during sustained workloads on the XW4600?

The assembly is designed to match the workstation's original cooling specification so the CPU hits its factory throttle point before the heatsink saturates.

How much acoustic noise does the fan produce when the XW4550 runs continuously at full load?

The fan operates at the speed profile defined by the workstation BIOS, keeping noise at the level HP specified for the original XW4550 cooling solution.
