i had this old comp given to me and i started tearing it apart and it had this http://www.cpu-world.com/CPUs/K7/AMD-Athlon XP 1700+ - AX1700DMT3C.html processor in it. anyhow...after taking the heatsink off i noticed a glob of goop on what i would consider the "back" of the chip. is this thermal paste? i thought the thermal paste was put on the "pin" side of the chip....hmmm, i'm learning.....slowly....
