I recently had to replace the video card in my Dell 9400, probably because it overheated after a build-up of dust in the cooling system. So I am now paranoid about the temperature control of the CPU and the GPU fans. I think that if I run gkrellm, I can set and observe the fan behaviour. However, I have to have the programs display on the screen. I have installed i8kutils and thought that I could use these conveniently. I thought I would find some config file to set temperatures. I haven't found one, and running "i8kmon -d -a -t 5 &" doesn't seem to work. As I am obviously confused, perhaps someone can help me. Thanks DP South Australia
