I am always looking for a Vista sidebar gadget to monitor CPU temp and fan speed but it never available on Gadget Gallery. The most CPU utilities related stuff are the duplicate CPU monitor gadget. Thanks to Dave for his comment on CPU Cool.
I did Live search and found CPUCool utility website. CPU Cool is small software/utility cost $17.95, which come with a lot cool features. It can monitor CPU temp and Fan speed together on what I need, a Vista gadget.
The limitation is it only support Vista 32-bit and Sidebar gadget is just a plain gadget, no any style was applied. To note, after setting display data to Vista sidebar you need to add it manually to sidebar.
