My fan is not running

Is the fan suppose to operate from power-up and keep running.Mine does not and my system freezes after 6-10 minutes operation.

The fan can run. Whilst fiddling with GPU the fan ran continuously as the GPU chip got hot.

The question is now, is not can the fan run,but should it run at start up and continue during use ad infinitum.

Most likely is that you need to replace the fan. Here's how to do it: iBook G4 14" 933 MHz-1.33 GHz Fan (1.33 GHz) Replacement
