Hi all, hope you are well. I own a Toshiba p100 notebook with vista business. The GPU is an nvidia 7600 geforce go and I have noticed that the fan for the GPU only spins when booting up. The moment Vista begins loading, the fan stops and doesnt come back on until I reboot (again it spins til vista begins loading). Now I can only presume this is a graphics driver issue or a BIOS issue(I have the latest driver and BIOS update). I use rivatuner to monitor the temp and under heavy load (3D gaming) the temp rises to about 90 C. This, I can only presume is not normal! As always, the fan doesnt kick in, even at 90 C. Now I have done some research and it seems this issue is not specific to myself. Under XP (I have tested it) the fan works fine, no overheated GPU. My question (after much rambling lol) is, should I be concerned about the lifespan of a GPU that reaches in excess of 90 C?
