That is an older method of thermal paste application, if the X61/s heatsink
is like the T61/p then it has enough pressure that the paste will spread
itself and not need to be spread. The approx. 3mm blob is what I would
recommend on the CPU side. If the chipset/GPU use thermal pads then there
may be too much clearance for paste to be used. I have seen that a few
times, but I have not worked on a X61/s before to this extent,. You also
need to be careful when using silver-based thermal pastes because they are
conductive.
