HP ZBook 15 G3
Microsoft Windows 10 (64-bit)

Hi,

   I've just started using a HP ZBook G3 studio with the HP ZBook Thunderbolt™ 3 Dock. I have the dock connected to 2 display port monitors (and the spec suggests it should be able to drive 5), mouse, keyboard, ethernet and my headphones. The dock's specification suggests the ambient operating temperature should be within 0° to 35° C, which is the case. However the dock is very hot to the touch, I've casually placed a murcury style thermometer on it for a few minutes (the case prevents the glass from touching the dock itself) and it's getting to the maximum reading of 41° C. The high temperature area on the dock seems to be located primarily where the power supply connects.

 

  Is this normal? Everything appears to be working OK now, although I did have a bluescreen caused by the USB drivers.

 

Thanks,

Alex.

The only Alert I have on hand for the Thunderbolt is the Alert dated 16-Jun-2016 regarding the G3 not detecting the dock.

What happens if you raise the dock up from the worksurface a bit, say place it on a "trivet" that provides for more air circulation all around the device?

 

If all else fails, you might check the outlet into which the dock is plugged -- check for voltage spike / higher than normal voltage reading.

Dock for Zbook 15 G3 also running hot. Plenty of room around all sides of the dock. Updated all drivers the dock instructions listed including graphics drivers. Only items plugged in are:

 

  1. Display Ports (x2) plugged into HP E233 Monitors - 23" 1920x1080
  2. Ethernet
  3. Power adapter
  4. Thunderbolt / Power combo cord to notebook

Great pro advice on how to cool. What is official take on whether heat is normal? Thank you.

The information provides the environment in which the dock can safely be used -- no mention of "how hot is too hot" for the device itself.  (I might have missed something...)
 
Were it me, I might try the "raise up and pray" method -- place the device on a slightly raised surface that allows air circulation all around the dock.  (Heat proof mesh trivet, maybe two inches or more above the work surface.)
 
IF you are using a power strip anywhere in the mix, make sure the strip and the power cord are of a heavier gauge (perhaps 14 gauge as opposed to the standard 12 gauge used on smaller devices).  Yes, I know, "never use a power strip" is the general / recommended advice -- not all of us can (or can choose to) plug everything into a wall socket.
 
Check my previous post -- I have updated it with the latest HP Alerts that may be relevant to operating the dock and peripherals.  Does software / firmware affect heat?  Maybe...

I have basically, the same setup as @SushiGuy1, in terms of connections, I haven't had any issues recently.

 

I ended up cable-tieing the dock to the back of my metal monitor stand, I presume the metal helps to disapate the heat. I can post a picture if you're interested. 

 

I also installed all of the firmware updates for the dock.

Checked a coworker's dock @AlexMcLellan and @Dragon-fur and it was warm as well. Maybe we can assume it is normal.

 

Will no longer worry about the heat. Thanks for the input!
