Re: Installing the Zalman CNPS9700 LED

If you really think I should take it off and redo it I will. I figured I put
enough on both. I didn't paste the whole areas to the edges. I did about 80%
of both. I'm leary about taking it off and on too many times and striping
the plastic screw sockets.
That reminds me to ask about only using 2 bolt screws to put the cooler on.
Why do they give you 4 bolts and what's this about being able to move it in
90% increments? I did only use 2 bolts to install it. I used the 4 longer
bolts to install the backplate but I only used 2 of the 4 bolts they provided.

This seems a bit, well I'm glad I have some input here of help. What do you
think about that procedure? Is this the correct series of steps so far?
Install the CPU chip first, then the backplate, then the cooler? Or backplate
first, then CPU chip, then cooler or does it matter if the chip is installed
before the backplate?
Any more help will be greatly appreciated.

What matters, is that the back of the motherboard be supported, when
you're putting pressure on the top of the motherboard. You can choose
whatever order results in good mechanical support for the motherboard.

When putting the plastic piece on the top side of the motherboard,
the Zalman video shows that the plastic piece has to be oriented,
so there is room for the hinge of the lever. The plastic
piece should only fit one way, and should leave room for the
lever to move through its normal range of movement. Since the
lever is free to move, you can install the CPU either before or
after the retention frame is installed and backplate added to
the back side.

I put a half-grain-of-rice sized bit of paste on the CPU,
squash it with the heatsink, and see how far it spreads. I
clean it off. and apply paste according to the instructions
that come with the paste. Some people do it different ways
than others (they either spread it, or they place a dot
in the center, and let the pressure spread it out). According
to the Arctic Silver instructions, priming and filling the
rough areas on the metal surfaces, helps improve the performance
of the paste. So an initial application, clean it off (doesn't have
to be "shiny clean", just wipe off the excess), and then the final
measured quantity, should give good results. A little bit of
paste should be visible at the joint where the metal on the
CPU meets the metal of the heatsink. If a lot gushes out, you
used too much, and should do it again. Too much paste, works
like an insulator. The paste is only there, to displace trapped
air bubbles. You're not supposed to build an "Oreo cookie" with
it :-)

I'm still on my original tube of Arctic Silver. So if you don't waste
it, the stuff lasts a while.
