To avoid CPU frequency to have an effect, why don't you disable turbo boost?

I run with turbo boost disabled usually, as this reduces how often the 
fan needs to cool.

On an intel CPU with linux, the following should disable turbo boost 
(which usually means reducing to a stable CPU frequency):

echo 1 | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo
