You are right, that program dener recommended won't work. Dell PCs do lack temp sensors on the CPU/motherboard. The only way to monitor the fan speed is to listen to it, because the temp sensor is actually in the fan, and tells the board to increase the fan voltage when it senses warmer air.
speedfan will atleast give you an idea the temperature inside the case is... i use it on my 2400 to monitor the hardrive temp.
