Xilence X5 (ZUB-XPTP.X5) and SilverTim (ZUB-XPTP)
The product specs and even compositions are listed on the backs of the paper inserts. The tubes themselves are not very informative.
Compared to the other products in this review, the thermal interfaces from Xilence are very open about their characteristics. Their thermal conductivity is declared to be rather low at 1.45 W/(K·m) for the X5 and 1.134 W/(K·m) for the SilverTim. The thermal resistance is 0.023°C-cm2/W for the X5 and 1.333°C-cm2/W for the SilverTim. The operating temperature range differs, too: from -50 to +300°C for the X5 and from -30 to +240°C for the SilverTim. Despite the differences in their specs, the two thermal greases are priced at a similar level, below $4.
Their color is similar, too, but the X5 is denser than the almost liquid SilverTim.
You can see that in the photos:

Each of these interfaces is easy to apply and remove without any trace.
The Zalman ZM-STG2 accompanies Zalman’s new coolers and is also available as a standalone product for $6. One tube contains 3.5 grams of this thermal grease.
The Zalman ZM-STG2 is declared to have a thermal conductivity of 4.1 W/(K·m) and a thermal resistance of 0.08°C-cm2/W. Its operating temperature range is -45 to +150°C.
This thermal grease is dense and viscous.
It is easy to apply in a thin and uniform layer and later remove from a processor.
That’s the last of the products to be tested. Let’s move on to the tests now.
