So I performed an upgrade on my Dell D620. The CPU fan was working fine before I took it apart. I swapped the processor from a Core Duo T2400 up to a Core 2 Duo T7200. It is recognised fine in the bios, and it boots to windows with no issues. However, the CPU fan is not working at all, and the fan control in certain applications (for example Argus Monitor) no longer recognises any fans. I ensured that the fan is still firmly plugged in and that there is no damage to the wires.
What could be the issue here?
