The unit I use is a NetGear R6300. It’s been running without a reboot for a long time and it’s been pretty stable, but… It runs hot as hell! So I started thinking about how to cool it down, and just as I was about to search, a coworker next to me said there are ready-made kits online. Sure enough, a search on eBay turned some up… and they were cheap, so I went and bought one.
