Why does my fan rattle after about 30min of use?

After about 20-40 minutes being plugged in the computer begins to rattle and overheat. Can this be repaired?

Hi @jhansome

It may be a faulty fan e.g. worn bearing or simply covered in dust causing it to not operate properly.

Here's the service manual for the laptop.

Go to p.51 to view the pre-requisite steps and then the procedure to remove the fan.

You can then check if it needs to be cleaned i.e. dust build up etc or if it is faulty.

If faulty search online for Dell 15 5000 fan to find suppliers that suit you best.

Since you have to remove the heat sink, check the condition of the thermal paste that is covering the CPU under the heat sink. It may have dried out and will need refreshing. Dried out thermal paste can cause heating problems with the CPU. Here's the ifixit How to Apply Thermal Paste guide that may help.

Hey, Jess

Your Inspiron fan or heatsink is probably loose. You can secure the fan in the laptop, or just install a new heatsink altogether.

Yes it can be repaired by replacing the fan and its thermal paste to possibly stop the rattling sound and stop overheating, I also recommend to put your laptop in a flat surface to avoid it from overheating too!

I hope that helps! Let me know if you have more questions
