Audio Hack: Mics and Fans

I bought this sleeping bag mat for a road trip two years ago and we ended up in hotels every night so I never used it. Now I pull it out when I'm recording voiceover and stand it up around my hard drives to keep some of the fan noise from reaching the mic. With the lower background noise I can sit a little further back off the mic and that helps get rid of all the little mouth noises. It kinda looks like it was specially made for this since it's got the egg crate surface and all the folds.
