As far as the thermal paste, I have heard not to over-do putting it
on, but there needs to be enough the seat the parts together for
proper cooling. And to definitely not block the cooling "shafts" that
are in those blocks, or pads that conduct the cooling.
Any secrets in applying the paste to where it doesn't seep into the
cooling ducts? I haven't opened it up yet, waiting for the parts and
the time, so I don't know how big or small those duct holes are. I
guess you could roll-up a small piece of paper and put it in the hole,
then let it expand to size, then paint the paste around that. I don't
know, but am open to your learned suggestions.
*blushes* Thank you J. R.
When attaching a heatsink to a CPU most manufacturs recommend using a
spot about the size of one HALF of a BB. Pretty small isn't it? IIRC
Apple's recommendation is to spread a thin layer on one (upper?) side of
the heat conductor. The key is that when you torque down on the hex
bolts as Jim described you don't want any of the thermal compound to get
squished out so you truly want a very thin layer.
If you could get a perfect metal to metal seal with no gaps whatsoever
there would be no need for thermal compound, but you can't so the
compound serves only to fill the microscopic gaps between the two surfaces.
Have fun with your project!
