First post here - read a few similar topics but didn't find my answer, so I thought I'd post my own to see if anyone has any answers. Thanks for any input!
I am looking to make a cooling pad (just for fun, not for selling). I have a bunch of fans from various projects. I have some designs but my hurdle is figuring out which direction for the airflow. I am going to create a wooden holder for the laptop with some fan controls and perhaps a docking station (usb, external monitor, etc), with a nice padded leather bottom!
I have a cheap laptop cooling pad and it draws air away from the laptop and pushes it out back (blower design). In my research I have found that there are also cooling pads that pull air in and push it onto the bottom of the laptop. Clearly both are a form of convection cooling, but what I am looking for is some data/study as to which is better.
ie. Benchmark with cooling pad taking air away vs benchmark with cooling pad pushing air onto the laptop.
