When I play games on my laptop, and I want to avoid overheating, I put some stuff under it. First I put something flat on my bed, such as a sketchbook or a thin folder, and another one under my mouse pad because bed isn’t flat enough and it gets bumpy. Then I put two thick(ish) items on the sketchbook/folder and place them apart from each other, and place my laptop on them so that the items (I use swedish-finnish dictionaries) hold it up by its edges. Only after that I plug in the mouse, the dvd-drive and the power cord.
I feel like I was performing some kind of a ritual.
(The truth is, my dog is Amaterasu!)
