Default Question about carputers

I have a question about carputers. Will it hurt a carputer to be left in a vehicle in sub zero temperatures. I know some of you guys here have them in your cars and I did a search and can't find anything specific to my question. I'm wondering if it's ok to leave in the vehicle or should it be taken out at night during the cold winter months. I know the touch screen should be fine but I'm more focused on the CPU. If you guys could shed some advice I would appreciate it.

Thanks,
Michael

nope, not at all. in fact it's preferable to really hot weather actually.

I take my subie up to tahoe all the time and leave out in freezing weather...nary a glitch with the carputer

UNTIL...I switched over to a fluid-bearing 2.5" hard drive. then the fluid would freeze up and I'd have to warm up the car for a little while before the hd would start. I switched back to a standard 3.5" and that problem went away.

Check out mp3car.com for all your carputer questions.

The major problem with computers and cold is the HD as ZenerDiode mentioned. But it also can take a long time for a cold lcd display to warm up.

As far as the cpu, you could mount it under the seat where the vents are to heat it up (and cool down in the summer).

I've seen extreme PC overclockers get their CPU way below 0. One guy even used liquid nitrogen to cool the CPU. They overclocked a P4 to over 5 GHz.

The only components I would worry about is the HD or the lcd. Get a HD with an operating temp below zero. Laptop HDs sometimes come with this spec. Also get one that can withstand higher vibration. I don't know much about LCDs at low temps, but it will prob be fine. It may take a couple min to warm up. While it is cold it may "ghost". That is what my iPod does. I've left it in the car by accident and it takes a couple min to warm up, then its as good as new.

Cliffs: You will be fine. Get laptop hd. Check opertating temp of HD and LCD.

I've run my omnifi (mobile HD based mp3 player) for 2 winters now without any problems. Once it gets cold (below zero or so), the HD won't spin up anymore, but other then that, computers like cold.

Try to get a hd with ball bearings instead of fluid bearings. Your balls may freeze but the ball bearings will not
