Dell Inspiron 3847 CPU cooling fan replacement help

[Jayhawk303]

Hello!

Our computer has been making a loud whirring sound from the fan at the top of the computer tower, I believe this is the CPU fan??

I'm trying to find a replacement, no help on the Dell website. Any suggestions?

Turn off your Dell, then remove its side panel.
Examine the inside of the case to see how many fans(processor, power supply, graphic card, etc.) it has.

If the interior is full of dust, you should blow it out.
Pay particular attention to the fans and heat sink units.

Shine a light inside the case, then turn on your Dell.
You should be able to see which fan is making a loud whirring sound.
