You find them in "hack" computer stores or electronics surplus stores ($1 each type deal). They vary in size between 1" and 4". You should look for anything that will fit inside your computer and it must be 12V (though you could use 110V I wouldn't advise). Just use a spare drive power cable to drive it. While at the electronic store, you could also get an oversized heat sink (an aluminum extruded comb) and glue it with heat transfer glue on your hard disk. Note that my computers are "ON" since last May (when I moved over here) and I haven't ever had any of these problems (albeit it's a bit cooler than most places).
