1.) Put it in a box with the vents facing out.
2.) Take a hair dryer and turn it as hot as it goes.
3.) Move hair dryer along the back vents for 5 minutes at a time, taking 1 minute breaks between applications. Don't keep the hair dryer in the same spot, have it constantly moving in a constant motion. Do this 3 times for a total of 18 minutes including breaks.
4.) Let it cool for 30-45 minutes, turned it on and got my Demon's Souls game save, I was so happy
