Typically fan request for AC pressure never more than 30-40% (and only that high on very high demand AC environment). At that level, can barely hear fan running.
At full tilt (90% DC for most PWM fan controllers), an 850W fan tends to make a little noise - but only see that level during track use due to ECT, IAT or oil temp. I'm ok with fan making some noise then - especially if controlling temps.

Dave,
We are going with the E67 controller along with at least one C6 fan control module and the C6 AC pressure switch as you outline above to supplement the Vintage Air controls as far as request for fans is concerned.. We have two questions:
1. We are wondering if we have to use a body control module to enable the AC pressure switch to provide a fan request signal to the ECM or if it can do so directly without a body control module?
2. We know you doubt we need 2 modules for our dual fans but
if we end up going that way, do you suppose the ECM will care that there are two modules receiving it's PWM signal vs one?
We are doubtful that it would be an issue since the ECM is just switching to ground but thought we should ask.
Thanks again for your help!
