We do quite a bit of soldering at .:oomlout:. and as all will know proper air flow when doing so is important. Until now we've been taking a hammer to the situation by turning on a large fan. However as the temperature begins to dip that solution is growing more and more unpleasant. To tackle this we bought some 80mm PC fans and cut up a small stand to hold them. Now soldering (and breathing) continues apace, just without the jacket.
