There should be a target chip temp function where it keeps them at a certain temp.
You could propose them that. Do you mean automatically reduce the speed of the chips? Unfortunately each change needs a reset, i wonder if its possible to change it while running without cg/bos(miner) reboots?
For the time being, this firmware is best for people who want to set things manually and not depend in any logic guessing, for good or for worse.
