Introduction :
When we first took a look at a Nanotherm product
it was their Ice and Blue compounds that very much rewrote the
rules for thermal greases. Instead of high concentrations of
heat conductive metals ESG developed a brand new formula devised
from special ceramic compounds in an optimised carrier. Not
only did this new compound offer performance on a par with Arctic
Silver it was the easiest TIM around to clean up, leaving virtually
no trace even when wiped with a dry cloth or paper towel. ESG
then went on to optimise their formulation even further with
the introduction of IceII and BlueII which in our experience
went beyond the original formulations both in terms of cooling
and in terms of ease of application. The original formulation
was, if anything, a little on the viscous side to apply evenly
but the new formulations are much easier to work with.
We knew that ESG were beavering away behind the
scenes working on several "top secret" projects that
they hoped would make a major impact on the cooling scene and
although the subject of today's review is perhaps the least
radical of all of those efforts it's still being billed as a
premium quality thermal grease that should have what it takes
to go beyond anything currently available. This is what ESG
are calling, perhaps understandably, Nanother Silver! Actually
to be more precise it's called Nanother Silver XTC where the
XTC denotes "eXtreme Thermal Compound"
Along with the Nanotherm Silver we'll be testing
out a slightly more unusual compound that for now we'll be referring
to as Nanotherm EXP (Experimental). Due to the unusual nature
of this compound and its early developmental stage I can't make
a lot of detailed descriptions about its properties but I will
detail its cooling performance alongside the Nanother Silver
XTC (referred to as Nanotherm Silver from here on in), IceII
and BlueII
As always let's start out with some specs for
ESG's Nanotherm Silver :
- Contains a highly optimized combination of sub-micron
to low micron sized Silver particles
- Silver particles are 99.98% pure and are custom milled to
our specifications
- Compound has a high density of silver particles; 80 to 83%
silver by weight
- Also contains a special blend of Boron Nitride and "Nano"
powders used in our Nanotherm II compounds
- Suspension fluid is a high temperature synthetic designed
for operating temperatures in excess of 500'F
- Compound is non-electrically conductive, based on our preliminary
testing
- Retail product will be packaged in clear, graduated 3 ml syringes
- Net weight of thermal compound will be 4.0 grams per syringe
- Suggested retail price will be $7.95 per syringe
