Grease Wars 3: Supercool Goo
Let the war
begin. The largest thermal grease war at TargetPC that is! Today, we compare
new versions to old versions and improved versions. This five greaser shootout
has a surprise winner with a surprise price. It's Nanotherm versus Arctic
Silver in a review that took three weeks of dedicated testing. I just hope
that the heatsink clip on my aging P3 holds out...
Ice & Blue
in two flavors: Ice & Blue
- Thick, Viscous,
- Does not
Separate, Leech or Dry Out
- Price: $4.95
USD for 2g/1.5cc
- Made with
99.9% pure micronized silver
- Does not
contain any silicone
triple phase viscosity
$7.95 USD for 3g/1cc

A woman asked the male driver about changing the car's oil and his reply was,
"motor oil is motor oil."
up your new P4 or T'bird screamer, I'm sure most consider very carefully every
single part that goes into the case. Except for some odd reason, the thermal
grease gets left out. Some argue the benefits when grease is substituted for
an inefficient pad, but is there is difference between greases themselves?
Can one be significantly better than another? If you recall my aging Arctic
Silver review, you'll see that quality of thermal paste varies greatly.
discovered with heatsink compound is that generally speaking, you want a thick
viscous compound. This is good for several reasons. First, a viscous grease
is less prone to drying out over time (months, years). Second, tiny air pockets
are less likely to decrease the tight coupling between heatsink and CPU.
is similar to Nanotherm Ice and Blue in that they both veer away from using
small micronized metallic particles. These Metallic particles aren't necessarily
bad; however, with all electrically conductive particles, some risk of damage
may occur either over time or under extreme pressure. No need to worry with
either Ice, Blue or Alumina.
3 is the new and improved version of the high end grease that started it all,
Arctic Silver. AS3 is slightly electrically capacitive and while a solid contact
area should be maintained, extreme pressure could cause it to become conductive.
contestants are the same as in Grease
Wars 2, with the exception of Blue. It is new and improved even though
I didn't specifically test the old and new revisions for this test.
and Nanotherm products do require several days of CPU cycling in order to
achieve maximum stability. Since this effect is particularly prevalent with
Ice, Blue and AS3, I chose to concentrate on these samples with multiple tests
performed over several days for each. As you will discover on the next page,
AS3 appears to do worse over time, rather than better. The Nanotherm products
are so stable that prolonged testing produced insignificantly different numbers.
be the last series of tests using my old Pentium 3 rig. The previous tests
performed in my older reviews are not comparable due to many system changes
such as moving from a GF2 to a GF3 Ti-500 and different overclocking parameters.
All further tests will be using a P4 1.6GHz overclocked to 2.0Ghz or higher.
