Climate sensitive case

Any suggestions for a case for my enviromental problems? I live in Hawaii and am searching for a case or modded case that can acclimate to the hot humid weather of Hawaii without pressing the limits of the processor specs. I am using a thermal take xaser 6000a (7 fans +2 on psu antec truepower 550w) my temperature is rating from 34 - 40 deg celsius. This is causing havoc with my motherboard which is continually shutting down on graphic intesive situations in where the board reports a 125 deg F on the processor. Any help will be most appreciated

I think the summer heat of Michigan is greater than that of Hawaii, if it works here it should work there.
