I work in a very cold environment, (naval outpost antartica) and we have run into a problem that is a bit of a pain. we just recently upgraded our computers at work and they wont start up when they are in this environment. our new ones will run if we blow a hair dryer on them for a few minutes to warm them up. we cant leave the heat on in the outpost cuz fuel is our life, and your never sure when the next plane will make it in. i've disconnected all the fans and closed off all the vents. nothing works except opening the case and using a hair dryer on them. does anyone know where i could get a case heater? (if such a thing exists?)

thanks in advance.

basically any type of 120v heater would work. if ur good with electrical you could wire it up to a switch like a gloplug in a diesel engine.

Well can't you just boot up the comp and then keep them running? They should keep themselves warm enough.
Though I think it's quite obvious that nobody here has actual antarctic experience.

How about water warming instead of water cooling?
Same stuff, though the water keeps everything warm. Perhaps use some liquid that holds warmth better.

but if it gets that cold id think the water would freez of course u could always pump like winsheild washer fluid in stead and before some one asked why cant he keep it on.....he said it was because of feul they dont know when their next dilivery will happen/make it.

oh, man, that sort of qoute brings me back to my days in the army...
really is amazing what you can improvise out of a diesel engine...
especially from a 28 liter, 1200 horsepower tank diesel engine... :laugh:


in any case, the lightbulb sounds like your best bet to me.
if you've been cracking boards cause of the temperture differences than the lightbulb should provide a nice and not too hot heat-source that should spread the heat out fairly evenly...

the problem isnt the computers at our main station, because they are always on and its a mostly heated environment. It is the computers at our other outposts that are not used as often, that are not heated and are not always on because it would be a waste of fuel. anyhow we tried a 60 watt light bulb that comes on when the generators start up. it raises the case temp to a toasty -10c in about 3 minutes. it seems to work very well. by the way, there is almost no moisture in the air so accumulation on things really isnt a problem. even the moisture from your breath turns to ice and falls out of the air.

thanks

i know this sounds really ghetto but you may want to place the comp inside a cooler for insulation purposes. one you get the rig heated you could let it get nice and toasty inside (sounds like im talking about a car..lol)

Sounds like a good overclocking environment. ;) Although it must be taxing to stay there so long...

Im thinking the hard drives will be your problem, as caps are rated up... err.. down to -30C arent they?

Hard drives hate cold like that.. maybe just get a little heat blanket and insulate it around the hard drives?

Everything else should be fine.. cept caps maybe..

Overclock the things.. they may just run BETTER.. LOL! :roll:

Depoends on th caps. But he said no post, so HDs wouldnt affect that.

This might sound ghetto, but get liek heatcores= # of computers, set up a huge loop, then use a pump to pump water heated by a torch or oven or something. I mean thats what heatcores are for.
