I got a great deal on a used MacBook Pro a while back, and it's a great computer and I love it, but the problem is it doesn't have any built in hardware acceleration for video. So if you are watching a long movie or doing FaceTime or watching a youtube live stream, or whatever, it *really* heats up.
This is a problem when you don't have air conditioning, because it REALLY starts heating up!
I don't know why I didn't think of this before, but I have this flexible cold pack, like for wrapping around ankles and the like. I put that on the table, and put a double folded towel on it, and put the MBP on top of the towel. I was thinking that maybe it would take the edge off, but it worked much better than I expected, it cooled everything way down, super fast.
Since the whole computer is one piece of aluminum, the whole body cooled down to a comfortable 72 degrees or so. If it was any cooler, water would start condensing on it! (It's 88 and super humid at the moment).
So this is great, I'm covered for the summer now. (In the winter, of course, I want all that heat.) Now I just have to come up with a cooling solution for the power supply.
