They sound really good, if it'd work during the night when I'm sleeping, I'd sooooo buy a hundred of them...
And it's so cold here now, that I wear two pairs of socks, three t-shirts and one hoody!
I've looked at some online sports stores and apparently you can get the higher-grade ones for 30 USD. Alternatively, you COULD make your own I bet. Duct tape a few of those blue coolers together, make sure there's padding so you don't freeze your neck stiff, and there ya go!
At any rate, I'm confused. Does the computer significantly increase the flow of heat in your room? Isn't it enclosed?
