does anyone use the cooler funnel method to cool/silence their A3 or other asic?
if you do, can precipitation like snow/rain or even dust particles affect the miner if the intake is sucking these things from your window?
In theory? Yes, but it's not likely unless the machine is like right near the intake source/window. In practice? If you're concerned, make sure the intake duct isn't perfectly straight and maybe add a vent cap (they're cheap) and/or an inline filter.
