T7810 temperatures too high
My T7810 workstation has a single E5-2680 v4 CPU and it idles around 60C (which is much too hot). The CPU fan runs, but slowly. If I run Intel's processor diagnostic, which pushes the CPU load to 100% for several tests, the CPU temperature quickly reaches max (86C) at which point the fan speed increases and drops it to ~70-75C. This seems excessive, particularly the idle temperature.
I've upgraded to the latest BIOS and it did not help (fan is set to Auto)
Has anyone else been able to get their system running at reasonable idle temperatures or have the BIOS folks simply decided to trade running the CPU fan more quietly in exchange for high temperatures?
Has anyone tried adding a 120mm fan to the rear of the case (it seems like it should have one)?

I am running BIOS A33 (released 1/10/2020)

After some more experimentation, The problem seems to be related to CPU utilization. Note, I am running Windows 10 Pro 64-bit.
The GTX1060 is only consuming roughly 7W when idle, so it should be fine, but the CPU was drawing nearly 40W at idle and the temperature was hovering near 60C. I swapped the GPU to an NVS315 and CPU power consumption dropped to 8-10W and idle temperatures dropped back down into the low-30s (just a few degrees above room temperature)...most of the time. However, when I don't touch the keyboard for a while, CPU power consumption still goes back up to 40W and temperatures return to the mid 50s. So the problem appears to be something causing high CPU power consumption at idle.
Has anyone had success running a higher-end GPU in the T7810? If so, can you share which GPU and what CPU and GPU power consumption and temperatures you're seeing? Has anyone else observed high CPU power consumption at idle with a similar configuration?
Thanks!

Did you ever find a solution to this problem?
I run 2 x 2650 V4 CPU and the one closest to the rear is getting very high temps. I have put the minimum fan to 50% in the Bios, but it now sounds like I am working in a helicopter...
I am thinking the fan might be defectuous. I run the system under ubuntu.

I found this link where they installed a liquid cooled TMJK2 for T7810 that you might want to look inyo and try.

while I am not convinced about changing the airflow structure, it is very interesting and inspiring to see these types of hacks!
thanks for the link!
