Well dang, I guess I'll have to get in touch with support to check whether mine is supported, and if not I'll either hack together a fan control script or try to track down one of the supported backplanes used so I can test it. Thanks for the heads up!unfortunately not the case - only certain backplanes supported for health monitoring, regardless if they have an i2c port or not. i ran into the same problem with my bpn-sas2-836el1
