Tales from a Ventilation Lunatic

[sternwake]

The PWM MSC powering the stock blower motor has come in quite useful again. I've driven to Florida for Xmas, and the spare bedroom was taken, so Fiona and I slept in the Van as it is a million times more comfortable than the air mattress on office floor, while it rained, and my regular intake fan shroud had its window closed.

I never ran dedicated wiring to feed the PWM MSC, but have been grabbing the nearby anderson powerpole that is there for the passenger side window fan shroud. That is 18awg so voltage drop is limiting top fan speed, but not a big deal. When driving I have just been using the 4 set speeds of the Stock resistor pack.

If I have the stock Hvac blower on very slow speeds sub 1.3 amps or so, and it is windy outside, gusts of wind affect the speed/noise of the fan which I find a bit annoying, but can drown out with more speed of any of the other fans.

Speaking of the intake fan shroud with the 180mm SSfm 181 fan, the 140Mm noctua industrial 3k rpm fan and the 120mm jaro, the 140mm Noctua, just failed. I was hoping for a connection issue, but 12vdc is getting to the circuit board fine and dandy. I have the second warranty 140mm replacement still in California, in the box, unopened, untested, and honestly, I doubt I'll ever bother installing it.

ALL these industrial Noctua fans have been lucky to last 6 months in this location. I'd rather be refunded than have another industrial Noctua. I'd rather have one of their newest non industrial fans, as I've had no issues with those, but one whose wires corroded off the circuit board, easily fixed.

I am trying to decide what to do regarding this 5th failed industrial Noctua. Is it even worth informing them? The 6 year warranty applies since the date I bought the first one 3 years ago or so. I don't think it is worth the effort to even package the old one up and send it back even if they send the shipping label to do so. Kind of disgusted really. Industrial....my ass.

I think that 140mm hole in my intake shroud will just get covered with Black Gaff tape, while I see if Delta has any 140mm offerings. My voltage buckers as fan speed controller, or LED dimmers, opens up a whole new area of powerful fans.
