Heat doesn't go up, it goes where the fans make it go.
yes, thats true, but in a closed case, can make a hot air bubble, as is happening with my build, even putting fans in the corners, i found a way to fix it, but that way, demands change some things in the case, and i modded it in the past
in the first one build i have the issue playing gta IV that temps went to 90 degrees...
changing the air flow, doing some news air access, in a closed case, finally i got 20 degrees temps playing 1 hour or more
but that test where when i had a 9800 gt, when i got the new cards, air hot bubble started to happen again
i know sounds like a dumb thing maybe what im saying and i can fix everything with a water coolers
is just about i want fix it in air, and not pass to water
maybe i just had bad luck, a bad cpu silicon, and a bad gpu silicon, thats probabbly, as usually, to my country, comes the worst technology, is not the same buy an i7 920 in my country, and buy it in united states
in united states will be first hand
in my country, second or third hand, and market guys of my country will be buying it cheap from international store, and expensive in my country " is what happen " also you have stores in some countries, checking the silicon of the cpus, what cpu uses less voltage and less temps, and things as that, and selling it cheaper or expensive
