Your chief concern should not be the air temperature but the amount of moisture that the computer is exposed to. As long as it is in a "dry" environment there shouldn't be any problems. However, any direct exposure to liquid water is asking for catastrophic failure [naturally]. Even prolonged high humidity can cause problems through condensation and increased probability of corrosion. Your machine will probably be just fine running 24/7 as long as you take reasonable precautions for situating the equipment. It will be more likely to fail if subjected to regular heating and cooling cycles during colder weather. <div class="gmail_quote">On Fri, Nov 11, 2011 at 5:01 AM, CJ Tres <<a href="mailto:ctres@grics.net">ctres@grics.net</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> IS it a bad thing to have a computer operating, say, in a garage during the cold winters? I realize there is some discussion on running 24/7 due to heat/cold expansion/contractions but it this machine were running 24/7 during winter is there any reason to believe it would be detrimental to the comp? Also wondering if anyone has any practical experience with storing CDs/DVDs under cold conditions. One report I read was full of technical terms but ultimately stated that there isn't enough data to say one way or the other. -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com" target="_blank">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div> -- “If I had a dollar for every time that capitalism was blamed for the problems caused by government, I’d be a fat filmmaker with a baseball cap.” - from a Facebook viral video <a href="http://linuxcounter.net/cert/544489.png" target="_blank"><img src="http://linuxcounter.net/cert/544489.png"></a>
