Use a strong liquid...I did it to my bro's Tbird 700 b4 he fried it. Try using rubbing alcohol, it should soften up the thermal pad.....than rub it off with a cloth.....do it to both the core and the Heatsink, k dude?

How about running it over with your car.

Use a lighter and flame it!! Burn the [-peep-] AMD!!!! BURN!!!
Dishwashing detergent and hot water usually works good, better than alcohol or acetone for the soft stuff. Or charcoal lighter fluid is perfect for removing stubborn gummy stuff. I've given up on Acetone.
The rubbing alch will usually work and won't damage the t-bird. There are solution compounds that you can also buy at the hardware stores that will remove it, but I don't know if they will harm the cpu or not.......
