Although I whirlpool and use a pre-chiller, I also use a CFC and do exactly what your asking. During this crazy heat down here, I reach my target temp of 140F then run one more pass through the CFC and end up somewhere around 80F-90F pumping directly into my carboys in my freezer. 3-5 hours later I'm usually around 60F and I pitch. 5 batches in on this new system and it's been working great.
