Here is another great idea form James Li. This time he used some scrap cardboard and an old case fan to make a laptop cooler. Let’s just hope his laptop does get too hot, cardboard ignites easily.
My laptop needs to be slightly elevated to cool it down, so here is a laptop cooler (unfortunately, not strong enough to be made into a stand) It even runs on USB power! All I need to plug it into a spare USB port. I stripped this USB plug form the masses of USB extenders that Dick Smith ship with their flash drives (that’s that black USB plug)
