Step 3: Power source
The power source for the 140mm fan it going to be a 9V 2.2A power pack. Though its not rated for the fan (12V 2.65A) it still has enough power for this project. My plan is to install a potentiometer / rheostat to be able to control the speed of the fan. Through testing the fan to see if it worked, I found it has far more suction then expected (awesome)
*I have recently added an air scoop to my design so extra air flow will be forced into the internal laptop CPU fan. Since the PS3 fan has far more suction than i originally anticipated, I'm putting some weather stripping on the chill pad to segregate the air flow, that way the PS3 fan doesn't rob the laptop of its natural airflow.
**I'll add the newly updates CAD drawings soon.
