DeathtoGnomesnot sure -40C is low enough. its gotten -20F here in michigan without the windchill factor.

Dr. NickAgreed. I've lived places where it gets below -40. Anybody in the Canadian plains will know what I'm talking about.

comtekAs a person who comes from tropical place I couldn't stand Australia Winter which was mostly above 0'C let alone -40C. Must be miserable living in that place. I feel sorry for you.

rtwjunkieWhere he is you have a distinct 4 seasons. Its all relative. I’ve lived in the extreme north of the U.S. where they take cold as just part of life during winter and can’t imagine sweating nonstop 6 months a year.

Yet where I live now I sweat 6 months a year just stepping to the car, and people here think nothing of it, and think if it gets to a few degrees above freezing that the Arctic ice cap has descended upon them, LOL. It’s all perspective. :)

DeathtoGnomesI seem to recall the wide spread panic Miami had when the temps dropped below 40F and then it snowed, i forgot if a state emergency was raised or not.

eidairaman1Where I am we have all 4 seasons in a day to a week.

Yes its cold here now, jacket weather

SlizzoI have no sympathy. You're in Texas according to your set location. :)

eidairaman1hat's fine I don't need anyone feeling sorry for me. Heck It Rain sideways here

DeathtoGnomeslaying down on the job will give you that illusion when you're worn out.

ArjaiUp here, we love it when it snows down South. Every news channel lights up with videos of Southerners trying to control their cars on icy streets.
:laugh:

nemesis.ieDo components inside a box, which is itself inside a vehicle suffer from wind chill?

Is the temperature inside said box going to be as low -40 if the outside is -40? Likey applying power to the components (and those nearby) will also provide some heating and then there is the vehicles heating/cooling system that can assist.

-20 F is -28C, so still within spec at that level too.

So it seems like a good (industry standard?) range.

kapone32If the car has a radiator it certainly would and take longer to get to ambient too. In different parts of Canada -40 could be the median temp on some days. As it stands in some provinces you have to plug in your car at night so the engine block does not freeze. The worry would not be when the car is running but from a cold start.

eidairaman1Northern US too.

There are battery blankets too

kapone32How could i forget. I remember going to Winnipeg (coldest city in Canada) one winter and marveling at those blankets I thought they were for babies when the clerk told me it was a for a car battery.

eidairaman1Mine was a piece of foam, i removed it to prevent cooking my battery here in TX lol

DeathtoGnomesthats a poor analogy because the radiator fluid has direct contact with the material thats exposed to the air temps, plus its usually mixed to work in cold weather, a computer chip has no such ability to be adjusted to work in varying weather.

kapone32Yes but the radiator fluid is different from the radiator. I am saying that the rad is directly open to outside so if it -40 outside and the car is off the components will reach that temp (as the cold air blows between the fins).

DeathtoGnomesall i can say is ... :banghead: :banghead: :banghead:
