Hmm, yep, if the cooling depends on moving a certain mass of air past a heat exchanger, then the reduced air pressure could put you over the threshold where heat buildup becomes a problem. At 4700 m, your ambient air pressure is only 51% of that at sea level, assuming a scale height of ~7 km for the earth's atmosphere. You need to move air *twice* as fast just to achieve the same amount of cooling. Perhaps if they overclock the fan motors? =P I think they keep airplane cabins at the equivalent of 10,000 ft, or just a hair over 3,000 meters. You're 1-1/2 times that... always. > But it is an interesting topic, right? > Lets see, next monday, when I do my last 10 days period in the mine, > I'll test the daily build which was recommended by Linus and further > more, I put my Jukebox in cotton wool to reduce the shock waves when I > am driving far from paved roads with my 4 x 4 Truck. Well, good luck anyway. You probably qualify as the highest Archos owner in the world (airline flights excluded) - at least in the elevation sense. =) _______________________________________________ http://cool.haxx.se/mailman/listinfo/rockbox Received on 2004-05-08 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
