Jaxeen Posted July 30, 2013 Share Posted July 30, 2013 So I'm just curious if anyone has been able to test this. Do systems at high altitude run hotter than when at lower altitudes? I'm in Denver (5200 ft) and I notice my temps at stock have always been considerable higher than others. One week I went to Salt Lake (4500) and I swear my temps dropped a consistent 2 degrees despite the room temp being the same. Anyone know how much of a difference altitude or humidity levels has on systems? Quote Link to comment Share on other sites More sharing options...
omega939 Posted July 30, 2013 Share Posted July 30, 2013 I think you've answered your question based on your curiosity on temps with your NB. It would be much better if you check the ambient temperature of the room where you place your notebook though.. Quote Link to comment Share on other sites More sharing options...
Jaxeen Posted July 30, 2013 Author Share Posted July 30, 2013 Well I wonder if there is a known science that would support this theory (lower altitudes run cooler temps). Also, if anyone has tested say in Cali at sea level, and at some other time tested at an altitude such as mine and noticed a difference.

svl7 Posted July 30, 2013 Share Posted July 30, 2013 I doubt a couple hundred feet will make a noticeable difference, the ambient temp has more influence. But I can imagine that air cooling is more efficient in lower altitudes due to the higher density of air. Quote Link to comment Share on other sites More sharing options...
chmod1337 Posted July 31, 2013 Share Posted July 31, 2013 You guys are forgetting the air humidity that has an effect on the thermal capacity of your cooling air. Also please consider the relativistic effect of the altitude on the cpu frequency, before you decide to move to a different location.

LeafyVegetable Posted August 2, 2013 Share Posted August 2, 2013 Haha my temperatures in singapore (pretty much sea level) are hot as hell, while in melbourne, higher up, is cooler. Depends on temperature of surroundings more than anything I'd say. Quote Link to comment Share on other sites More sharing options...
gesture505 Posted August 4, 2013 Share Posted August 4, 2013 I would imagine that it was probably a difference in ambient temperature in your case. I found a fairly old reference describing things to consider in cooling design against altitude. The altitudes described are much higher than the ones in your environment.Coolingzone.com - Cooling electronics at high altitudes made easy Quote Link to comment Share on other sites More sharing options...
jqtxpyer Posted September 25, 2013 Share Posted September 25, 2013 Well it is only logical that at high altitudes where the air is thinner there will be less volume of air for your fan to pass over your graphics card heat sink to dissipate the heat it generates, causing the high baseline temperatures at those altitudes. The more particles of air to absorb the radiated heat off the heat sink the more able your fan is to lower your temps. Looks like you need to seek lower ground!

crossday Posted September 28, 2013 Share Posted September 28, 2013 It is for sure that lower altitudes get lower temperatureEven high altitudes site are cooler than low altitudes, but the air density is lower than the low altitudes site.It seriously affect the cooling down effect Quote Link to comment Share on other sites More sharing options...
thunderman Posted October 7, 2013 Share Posted October 7, 2013 I tested my newly acquired GT60 (4700mq and 780m gtx) repasted with IC diamond onboard a flight from Atlanta to Paris, playing Crysis3, the only thing that stopped me was food being served...Honestly i noticed no real difference in temps, it ran quite cool with cooler-boost Cpu @ 68-70 and gpu @ 75-78 which is really in line with what i experience at home with the Ac running.So cabin pressurization seems adequate.
