we keep hearing about people lapping their
CPU's & heatsinks.
i have no problem with it; it's a labor of love,
it's fun for the people who do it.
But - if Intel or AMD are shipping out-of-flat
CPU's that's newsworthy.
same for Thermalright. they are shipping
out-of-flat heat sinks. having worked from
1980 to 2004 as a mechanical engineer, i
flinch a little when i hear about that.
it looks like TR is machining the parts &
assembling them, and they go out-of-flat
during assembly.
it is a CINCH to fix that. all TR needs is
a fixture to hold the heatsink very steady
while they do one final fly-cut. they might
need to add .010" (hundredth of an inch)
to the copper piece on the bottom, to make
sure the post-assembly-fly-cut doesn't dig
into heat pipe material.
how about an AT article on this subject ?
i think it would get a lot of reads. i haven't
seen anyone else, including Frostytech,
address this subject.
it's not that hard to use a dial or LCD
caliper. surplus granite metrology blocks
can be had cheap. the ANSI spec for Flatness
is easy to understand.

i like this picture, you can see the text on the
other side when they scanned some document
relating to Y14.5M-1982, the spec i used most
of my career. the flatness definition is the
second one down on the *.jpg.

there's a lot of hungry machine shops, if
you wanted to farm out the measuring part
of the article.
