I did in fact try that, and while it lets me change the values, they
don't actually seem to affect the kernel's idea of when the fan should
come on, if at all. I set the active trip point to 45 C and the passive
to 50 C, then ran a compile to see if the fan triggered. While the
temperature got above 50 C, the fan never came on. In fact, I don't
know if the fan would come on even if the originally-specified trip
points were reached. Either way, this isn't exactly the most comforting
situation to observe.
