Zotac ZBOXHD-ID11 Case Positioning Impact on Fan Noise

Thu, 27 May 2010 19:55:00 +0000

As I was testing the ID11, I noticed differences in the thermal behavior based on how the case was positioned.
I tested three positions; case open, case vertical, and case horizontal.

This is the fifth post in a series of posts related to the Zotac ZBOX ZBOXHD-ID11.

Summary:

Place the case in a vertical position for best cooling.

I used the Beta BIOS for testing. I let the system sit idle, placed it under load, then back to idle, while I recorded the fan speed and temperatures. The ambient temperature was 21C / 70F.

Zotac ZBOXHD-ID11 Beta BIOS Reduces Fan Speed and Noise

In a previous post I measured the fan speed and noise under load, and I found it to be unacceptably high.
Zotac support notified me that a new Beta BIOS is available that addresses the issue.
In this post I measure the difference between the release BIOS and the Beta BIOS.

This is the fourth post in a series of posts related to the Zotac ZBOX ZBOXHD-ID11.

Summary:

The Beta BIOS reduces the fan speed and noise significantly.
The default BIOS values need some adjustment to get acceptable results.
Similar results may be possible with the current BIOS by setting the target temperature to 65C.

The Beta BIOS was first announced on the global Zotac site, it only later appeared on the US site. I would recommend that ID11 owners look for updates on the global site instead of the US site.
The Beta BIOS is available for download from here.
