Nvidia L40S overheating and exclamation mark in device manager

Hi to everyone,

I am new in this community so forgive me if I completely missed category and for being complete noob, but I need your help.

Let me briefly describe my situation…

I am trying to help my friend to setup nvidia L40S GPU in his Dell Precision 7875 workstation and the first thing I discovered that this GPU comes in compute mode by default meaning that no video output is enabled through its DP. Correct me if I am wrong?
Because CPU does not have integrated graphics we installed nvidia GT 1030 to have video output and to use L40S for other computing purposes my friend needs in his work. In windows device manager under display adapters category both GPUs are visible but they both have exclamation mark and for L40S it says that it cannot start because insufficient system resources exist to complete the API. Installing latest drivers for both GPUs did not resolve the issue and L40S gets so hot, like 100 degree Celsius, you literally cannot touch it for two seconds or you will burn yourself, and PC fans are spinning on max. That does not seem to be normal for GPU that is basically idle?

If anyone has some advice please help me.

Anyone?

I have found this list of VGPU certified servers and according to that Precision 7875 is not compatible with L40S. I assume that is the reason why its not working, but can someone 100% confirm this?

That is a passive card that relies on a server with powerful fans and forced front to back air flow, it is not really suited to workstations because of this due to the noise of the fans required to force air through it.

Thanks for the reply. I am aware that it L40S relies on passive cooling, but I am not sure if its normal to reach such high temperature while just being idle without any computational work.

You can monitor the power consumption via software, if the power consumption is very low and the clocks are idle you need higher pressure air flow.
