I tell you more, to better understand CPU demands of a DAP. The official lowest speed of RockChip SoC is 216MHz. For years, I add 126MHz to the line, and this is the frequency used most of the time during music playback!
In general use it does not matter at all.
That software cooler is always there: it is implemented at the kernel level. My change, mostly, to lower the limit to 70C instead of 80C. Most of the time the SoC runs under 50C. I don't believe you want your DAP to run continuously with SoC temperature over 70C, but that was you asked for. Do you? Also, please note, that in DAPs, the battery is very close to the SoC, and high temperature affects the battery life.
If you can incorporate SetCPU, that will open up lots of flexibility
