Introduction
If your Alienware X51 PC begins to freeze up or shut down at random points, you may need to replace the fan (refer to the Troubleshooting Guide for more details). Replacing the fan, which helps with cooling down the processor, is as simple as unscrewing the fan. This replacement can be applied to the Alienware X51 R1, as well as the other models (the R2 or R3).
