Previously, we had been instructing customers to install fan
control software to speed up the cooling fans to provide additional
cooling. Now, the version 1.20 driver includes a fan speed control
daemon. This eliminates the need for a separate program to control fan
speed. We have recently updated our fan speed control daemon to support
the new 2010 Mac Pro (MacPro5,1) platform. It is bundled in the current
driver release for 3Gb and 6Gb ExpressSAS RAID adapters.
