1) If there was a pile of dust and dirt in the vent(s), you may have simply blown it all back inside the laptop. (Like a dust blanket ... which will drive the temps up).

 

2) If you used compressed air to spin a fan faster than it was designed to spin, it can ruin the fan bearings and races.

When you blow through the fan you should place a pencil, eraser end first, through the fan to keep it from spinning.  This will not only protect the bearing, it will allow you to blow completely through the fan blades.

 

Most fans have a sleeve type bearing which is not intended to be used with the kind of RPMs you would have when using compressed air to blow through it.


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
