The fans, as has been pointed out in another thread of yours, are actually running at 2000 RPM even when the computer is cold. They simply speed up as the CPU temperature rises. Under OSX they are usually running at a substantially increased speed by the time the computer reaches 70 or 80 degrees (though still not flat out). Under bootcamp the 'stepping' may be different, but the temps in the 70 to 80 degree C range you mention are not a problem regardless.
