I use this setup but can tell you it will take longer than 5 minutes to cool your wort. It usually takes me about half an hour to chill 11 gallons down to pitching temp. I usually let it go a good 45 minutes to and hour so I can pitch the yeast into a cooler wort and let the temp gradually rise once it is all in the fermenter.
