When I tried first the supported modes were only C1 and C2, but using sysctl again later I found that C3 and even C4 were available. I wonder why it changes while running. I tried with C4, but I get no significant change in temperature. Since the main problem is hang-up from overheat, is there any progress in having powerd slow the CPU when the temperature is too high?
