Abstract
A fan speed testing system for testing the rotational speed of a first fan, includes a switch module, a comparison module and a load module. The switch module outputs control signals. The comparison module receives the control signals and provides a first voltage according to the control signals. The load module receives the first voltage and outputs a second voltage to the first fan. The load module feeds the second voltage received by the first fan back to the comparison module. The comparison module adjusts the first voltage to the load module according to the second voltage received from the load module.
