nvidia-smi.exe, the actual application, was installed with the Windows Nvidia driver. I have used it on both the C2070 and the M2090 systems to compare what can be reported. As a result, I am pretty confident that the M2090 does not report temperature. Percent of memory usage is reported which is especially important to know when the project exceeds the memory of the GPGPU.
