hi
my blizzard 1240 came with a fan fitted as std DCE MODEL
it should be glued to the top corner of the cpu next to the battery in that same corner you will see a small biege block?? next to it are 3 solder terminals
the power leads RED wire goes next to this block and the black goes on the end (middle vacant)
you will have to leave the trap door of and raise the 1200 a couple of mm so that the fan doesnt touch your desk
hope this helps
