Back in March were patches posted by ARCTIC Cooling for an ARCTIC fan controller driver for Linux. Typically we aren't used to seeing desktop/enthusiast focused vendors providing such Linux drivers for peripherals directly but the sad fact is most often it's left up to the open-source community to reverse engineer and create such drivers for Linux. Making it all the more surprising besides it coming from ARCTIC Cooling directly was that at the time they didn't even have a fan controller product with USB interface. Well, now it's launched and in turn is a great USB fan controller for Linux systems and retails for just $9 USD.
