I want to reduce my temperatures a bit on my laptop without opening it up and without a cooling pad, will it damage my laptop if I spray compressed air into the back vents and use a vacuum to suck it out? Thanks.

Also, please give any cleaning suggestions.
 

After I did this, I feel my temperature is even higher.
