Set aside the bottom cover.
Note that the cooling fan is probably dusty.
Do not use a can of compressed air to clean the fan. They can shoot cold liquid and crack fragile fan blades.
Insert a spudger or screwdriver to keep the fan blades from turning. Use masking tape and soft old toothbrush to clean off the dust.
