Has anyone tried using these (quite expensive) fans to pull air through a 2" thick heater core? For that matter, does anyone have both the
14dB and the
11dB models? From the photos, the two
look identical, both draw the same power, so I'd
guess the difference is a resistor...? Which would mean the 14dB ones were more appropriate - and then I can add my own resistor/rheostat/diode-stack/whatever to adjust down if necessary.
I'm also
guessing that I'd need to "stack" a pair of these to get sufficient pressure - but maybe not (?) as these fans are
designed for low speed / low flow and may have stall points low enough that they're OK for what I'm doing.
