Occasionally you see a heatsink glued directly to the processor - most
often in Packard-Bell machines.  I have always assumed it was done with
some variety of epoxy, but I don't know where you can find epoxy with
good thermal transfer characteristics.  The "silicon glue" John mentions
is quite sticky, but is not meant to hold parts in place.  Its purpose
is to eliminate air gaps between the processor and heat sink (which
"helps the heat transfer"), and for this reason is often called "thermal
Compound".  

Jon's suggestion of a fan that clips directly to the processor is the
easiest way to take care of this.  And use thermal compound - it
improves heat transfer quite a bit.
