Hi @sds1013 ,
There is no picture with your question.
Here’s how to add pictures to your question in ifixit [guide|21499]
In the image in Step.6 of the [guide|106113] guide, (laptop model you selected), you can see the heat sink covering the CPU. It is part of the [https://www.ebay.com/itm/13NB05Y1AM0102-Asus-Q302L-Q302LA-BBI5T14-CPU-Heatsink-Cooling-Fan-/282011734991|heatsink/fan assembly] (supplier example only to show part and cost)
If you have a different model just search online for ''Asus (insert full model number) heatsink/fan assembly'' to find suppliers that suit you.
