  • Winter greatness...*sigh*

    Wow. Sorry to start a new thread...just thought i'd kick up a discussion. It's been so cold here lately, with the windchill its been below -40 these last 3 days. My computer takes probably 20 minutes of driving at least until it warms up enough to spin the hard drive. Even then it doesn't always start up.

    I kinda like the idea of it slow-warming itself to fend off the chances of condensation. But wow. What a PITA! I'm deff going to look into maybe getting a CF daughterboard for the OS at least and maybe a few songs to tie me over until the HDD spins. I have an 8GB CF-I card for my camera that supposedly writes at 125x. Although i'm not a fan of this way of describing the speed (125 times what?) Will it be a noticeable difference (ie. slower) than the HDD?

    Anyways, to any other northerners out and about, enjoy the cold

    Don't worry about condensation unless the humidity is high. In the winter, this is not usually an issue.

    The CF launch idea is one way to go. A ball bearing drive from a desktop machine is another way to go. The CF idea is more 'elegant' IMHO.

      I guess thats true eh...cold air hardly holds any moisture. But to be on the absolute safe side, what about putting those silica gel packets into the computer case to absorb any excess moisture that may be lingering?

        These type of posts always come up at this time of year. It gets down to -40C here too, so I know what you have to go through. CF seems kind of slow, and for the same price why not just get an automotive grade drive? Less hassle and you dont have to deal with the limitations of a write filter. As for condensation, cold air doesnt hold much moisture. But you could also get fans to blow over your entire system to remove moisture as well.

          hmm it was like -10c here and mine took a good 15 sec :-P haha sry that i cant help but just wanted to share

            Yeah mine works down to about -15 before it starts lagging/waiting for the HDD to spin. Just sits with the VIA logo on screen waiting for POST.

            That would be sweet. I would love to...little out of budget right now considering i already own an 8gb card for my camera.

              They wouldn't absorb enough moisture quick enough, IMHO. Honestly, I think that you will be OK.

                Erm, a dumb question - why would you get condensation - with ambient running -40?

                  Some people have their carpcs in the interior. When the interior warms up + you breathing out warm moist air, the air is humidified and when the car cools down later on, that moisture must condense somewhere. Well, that is my theory anyways. But I doubt condensation is as big of an issue as it is made out to be, unless you are taking your carpc indoors from the cold then immediately booting it up.

                    Yep, I know the mechanics, the reason why OI am asking is that I have been a Hall of Fame overclocker, using phase-change systems down to -50 and beyond, and only ever encountered condensation when you allow moist air to come in contact with the super-cooled surfaces...provided you are way below ambient temperature.

                    Now, what happens here is just the opposite, where everything, including ambient air temps are way down, and not to mention lack of moisture in such cold air.

                    When you start up your computer first, it will rapidly warm up, and anyway, being at approximately the same temp as ambient, where/how would condensation form?

                    Unless you somehow keep the pc thermally isolated, and put the car interior heater to full blast, and then subject the ice-cold pc surfaces to the warm air, which, btw, has to be fairly moist, maybe then condensation will form.

                    Enlighten me if I am wrong, but I would like to see some practical proof

                    Not sarcastic, just curious, as this goes against logical for me....

                      my old setup has no problem with winter weather, the new setup however, is more expensive but much less effective for winter. Hard drive fails, and xenarc fails too.

                        Why are you worried about condensation? Condensation occurs on stuff that's colder than the ambient temperature, and the carpc should be quite a bit warmer

                          Blowing warm air over a cold surface will cause condensation on the cold surface.

                          This would be my only concern.

                          I'm working on a suplimental warming scheme for my trunk mounted system as well. Haven' worked out the details yet but I'm getting close.......

                          I'll post something if I ever get close to a final stage.

                            Also note that mp3car store has an automotive grade hard drive that has temperature specs down to -30F. Here's one, there are at least two listed in the store.
