So I got yet another anon email today and inside was this handy little SMC config tool, thanks to the anonymous author for a great release (IMG:
smccfged v0.3
-----------------
thank you, scene.
-----------------
purpose: modify the thermals of a given decrypted smc_config.bin
either overwriting smc_config.bin if --outputSMCCfg is not provided
or writing an output file as provided via --outputSMCCfg
limitation: this program will
- force targets to be between 40 and 80 degrees celcius
- force shutdowns to be between 60 degrees celcius and
- the current smc_config's shutdowns
- force targets to be lower than shutdowns
note: this program was built to be used with an ibuild-decrypted
smc_config.bin and fbbuild. fbbuild will error if for some
reason the CRC calculation is incorrect and this is a good™
thing. pay attention to fbbuild's output as it will error yet
still produce an image!
the algorithm for calculating the SMC Config's CRC was provided
here:

usage: smccfged <options>
--inputSMCCfg=<decrypted smc_config.bin>
--outputSMCCfg=<still decryptedfilename>
[optional; if omitted, input file is overwritten]
power usage options: (all required)
--powerUsage
--targets=targetCPU,targetGPU,targetRAM
--shutdowns=shutdownCPU,shutdownGPU,shutdownRAM
