I literally hate when this happens. A thought occurred as fast as that last email was sent. Low income types like myself don't always have enough pennies to rub together to even buy a cheap fan of any kind on demand. Doesn't mean we've completely run out of alternatives. The dogs busted my first laptop fan's USB connection couple years ago, but I still used the stand part of it successfully as a coolant aid for another year or so (until they broke that, too). ANYTHING that can *safely* get a laptop off the desktop surface helps even if no extra fan is available in an emergency. Give air every chance possible to circulate all around the machine. Mine's currently sitting on top of... knitting needles. They're placed so that they are not near the hottest parts of the laptop and so that they do not interfere with any other type of airflow, either. Just another #Life Lesson Learned the Hard Way due to losing couple machines over the years k/t the whole low income thing, yada-yada-grin...
