What version of cudaminer is it i keep seeing? Being every screen shot lately reports the users temps?
It's the latest compile from source files on github. There was an update on github ~2 days ago. If you compiled from that you should see the new temp readings. That said, the latest compile is a little slower for me compared to the previous version (scrypt-N at least, haven't tested other algos).
The NVML api only works with the 64 bit cudaminer version on windows. nVidia doesn't provide a 32 bit NVML DLL.
Now unfortunately the 64 bit cudaminer mines a bit slower in scrypt and scrypt-jane... I wonder if it is possible to combine 32 bit CUDA device code with a 64 bit host code?
