    I'm sure that has something to do with fan rpm control. When you powerup your pc the cpu is cold and the fan spin slower, by the time it hits winboot the cpu becomes hotter and the fan start to spin faster.
    Nothing to worry about.

    Is the machine crashing? Can you smell burning?

    If not then you can assume all is well.

    The fans will not spin up until the computer passes POST where the computer says everything is working correctly than boots up.
