OK, *utter* silence is a bit hard to reach at temperatures above -273.15 degrees Celsius.
Normal people can´t hear anything below 20 dB (some people though hear Elvis on a daily basis). The 80 mm Papst 8412NGL fan is rated 19.4 CFM and 12 dB, meaning that 5 such fans gives a noise level of 19 dB (pretty close to dead silent) and almost 98 CFM of airflow.
Good enough for a chimney?
