Let's get one thing out of the way first. If you don't have to be inside, then don't be inside. If you're working during the week and the office has no air-con, this one's for you. However, if you're moaning about the heat because it's making you sweat while playing Oblivion, get the hell outside, find some friends (IRL, LOL) and enjoy the weather.
Now then, you've tried opening every door and window, and you've tried working with the laptop outside, but that damn sunlight just kills your ability to see the screen. Sounds like you've done exactly the same as me, and we're all still roasting. Time for a more inventive solution.
So, I did a quick scout about the room and in a matter of moments devised a way of freeing myself from a sweat-ridden day.
First up, I dug out my old watercooling (no water required for this creation, though.)
I just needed the fan off the radiator. It's a Panasonic Panaflo FBA12G12H, that makes it a quiet, but decent flow-rate 12cm fan; or it would be if the bearing wasn't knackered. Instead it's a noisy, decent flow-rate 12cm fan, especially once I re-pinned it to run at 12V, having spent its previous life at 5V, oh well!
Next bit of kit, something to power it:
Ah yes, the venerable Icy-Box. I still use it as a backup drive, but for now it'll have to serve another role...
Give me your 12V powah!
From here on in it's simple. Plug the fan into the molex, situate the fan where desired, then power up the Icy-Box.
I call it the Icy-Flo, for obvious reasons, and you know what? It's awesome! Now I'm sitting comfortably, providing I keep my fingers away from the Icy-Flo, in which case my typing ability might be severely impeded.
Digg me!
