Do they try to deceive when they price their top pick by the gram? On
average, how many CPUs will five grams cover?
They also low ball the $20.46 plus shipping price available at
newegg. Maybe it all works out for a guy who builds one or two PCs a
year. In my particular case, this is a better bargain:

If you look very closely, you can see three white tubs next to the big
silver can. Mouser sells a small white tub of grease for $155.85.

It doesn't sound like they tested thermal conductivity. They probably
believed claims.

The Dow Corning is rated 2.5 w/mk, which is the only one I believe.

This sounds like a weird gamer cult.

Yes, 'tritium' based thermal paste? I would not want it around:
https://en.wikipedia.org/wiki/Tritium

Tritium has a half-life of 12.3 years...
http://panteltje.com/panteltje/tri_pic/

I have a nice tritium light in the shower..
enough light to see when it is dark...
http://panteltje.com/pub/tritium_light_all_img_3242.jpg

And 'ion' ?? makes no sense.
If you scroll down to 'Composition' it shows something different
Gallium Indium Tin and Zinc..

So do not believe everything written
well some thing anyways:

https://en.wikipedia.org/wiki/Galinstan 16.5 w/mk

but it eats aluminium so you need to use a copper heatsink or heatspreder

The 'paste' used by chip makers to attach their dies to the chip
substrate media is most commonly a Silver filled conductive epoxy.

Some of the stuff in the Teds list claim 70 w/mk.

Metal alloys have bad thermal and electrical conductivity. A CPU
against a very flat copper heat sink probably doesn't benefit much
from an exotic thermal paste. The important thing for a filler
compound is good flow and small grain size.

The universal 16.5 number is suspect too. People probably copied
people on that one. Real w/mk measurements wouldn't be all the same.

Two planar sutfaces mated and utilizing ANY 'thermal paste' of ANY
nature does little because it ONLY fills out the non-planar voids,
which should be a small number tostart with. Paste is for folks who
do not know how to design, much les implement precision sink-to-
device mating scenarios, which a mass produced product may or may bot
exhibit. It all comes down to the quality of that mated pair and the
process which manufactures such matings in an automated production
environment. Perfectly planar devices and sinks used on prefectly
planar scenarios can almost be used the same way two quartz surfaces
can meld when mated. Remember, the paste is only there to fill the
relatively tiny voids encountered in a mass produced product.

Onesy twosy items can be handled individually by assembly folks.
But those days are gone. Not much is out there for custom setups.
