This cooked my Mother-in-laws 800 Mhz Duron. She loved the game, and so left it running all the time.

And no, you shouldn't need to install a cooler. If the game requires special hardware, it should say so on the box, under "Requrements". This isn't billed as a graphics intensive game, and it isn't aimed at the hardcore gamers that might install special coolers. It's aimed at little old ladies that can't afford to replace their fried CPU or MoBo.

My Mother-in-law is lucky 'cause I bought her a new systems!
