GPU Feed Speed - Alienware R4

[thetravellor]

Hi there, the tool does not report fanspeed from an Nvidia 1070 GPU installed in an Alienware 17 R4.

Hwinfo reports this via the COMPAL EC category in RPM for both the CPU and GPU.

Out of interest why do you seek to issue fan speed as a %, RPM would be better. You cant have an accurate % unless you know what the upper limit is - which can change with a fan.

Hello, This tool is essentially a simple wrapper over NVIDIA NVML library. The main reason I wrote it was to monitor our GPU servers when I was in MSR. Tesla GPUs have passive cooling (i.e. no fans) so I never really tested fan speed counter. Unfortunately, I do not know why it does not work on 1070 - I don't have Windows machine nearby to test. As for the percentage vs RPM: % is what you get from the corresponding NVML function. My guess would be that NVML gets the actual RPMs along with upper limits and converts it to percentage. You are absolutely correct that this depends on parameters of the fan but I do not know how exactly NVML handles that.
