Is your Dell laptop overheating?  Be very careful as prolonged exposure to excess heat can cause your laptop to break down.  Heat can cause damage to your components like; motherboard, processor, video card and other vitally important devices.  One of the main causes of a Dell laptop overheating is cooling fan failure.  When your fan is not spinning or not moving at a fast enough RPM, it is not doing its job of removing heat from your notebook.  Cooling fan failure is mostly contributed to the accumulation of dust within the fan itself.  When too much debris or dust accumulates the fan will begin to fail.  Keep your cooling fans clean so that they can run smoothly.  If you notice that your laptop fan does not turn on at all, you may need to replace it.  Dell laptop motherboards are designed with temperature sensors that automatically detect excess heat and turn on the cooling fans.  If your Dell laptop continues to overheat it will shut down immediately in order to prevent damage to your notebook.  Do not attempt to keep using your laptop, a simple cooling fan replacement can turn into a complete motherboard repair and your repair costs will go up. 

If your Dell is equipped with a diagnostics program, run it and test all of the fans.  If there are any problems, the software will tell you that it could not detect the proper RPM for the fan in question.  Dell laptop overheating can also be contributed to the environment that it is being operated in.  For example, if your workspace covers or inhibits the cooling vents, it can cause Dell laptop overheating.  Keep your cooling vents free and clear of any obstructions so that the laptop can remain as cool as possible.  It is important to replace a faulty fan as soon as it is detected to prevent costly damages.  Visit our Dell laptop fans section and find the fan you are looking for.  If you need help with installation or need tips, contact us for free advice.
