HP focuses on providing high levels of user productivity during the workstation design process� Low acoustic noise
output is a key factor in enabling high user productivity� The HP Z Cooler is an example of HP’s commitment to user
productivity�
In addition, studies have shown certain kinds of acoustic noise are more distracting than others, especially higher
frequencies and irregular modulations� When a workstation executes a heavy cyclic processor workload, the fan(s) may
ramp up and down rapidly with the workload, creating these irregular modulations� The improved ability of the HP Z

user experience even under the most demanding processor use�
What are the benets of the HP Z Cooler?
The primary value of the HP Z Cooler is in the reduction of acoustic levels associated with cooling the CPU, the typical
primary source of system acoustic noise� Lowering system acoustic levels enhances end-user productivity�
The HP Z Cooler employs a single hermetically-sealed 3D Vapor Chamber unit with no pumps or hoses, so it has the
simplicity and reliability of traditional heat pipes with better thermal performance than a liquid cooling system�
How does the HP Z Cooler acoustics compare to the standard cooler of the HP Z440/ HP Z840 and the solutions
provided by previous platforms?
