I haven't seen it mentioned yet but what are the fan speeds like with
Fedora vs. FreeBSD?  Many laptops have BIOSes that are not fully
standards compliant and it could be that Fedora is doing something
different than FreeBSD when interacting with the BIOS when it comes to
fan speed control.  Unfortunately I can't give you any more help than
offering this as a possibility.
