The other question that I marked as answered was how to set things on/off and did not answer how to reduce heat. I have had some success with turning off devices in the device tree but I cant seem to get anything better than 10 degrees. I saw this question Reduce idle power consumption - #7 by campbell and that someone had success with reducing the cpu frequency that is the only reason why I asked about setting a new frequency to reduce heat.
In the documentation it does say 900MHz and 1.2GHz are the only clock frequencies but gives a range starting at 650MHz, shouldnt it be possible to then set the clock at 650Mhz at least?
Thanks
