PRODUCT SPECIFICATIONS AND FEATURES
“COOL-SILVER™ has been designed to enhance the performance of high-end processors, and has a measurable performance advantage in dropping the semiconductor junction temperature compared to top competitors with the same heat-sink and CPU. AI Technology has more than 25 years of experience and successes in helping military, aerospace, computer, and super-computer manufacturers with thermal interface materials. Together we have created some of the most reliable electronic devices and computers on the planet. AIT is now reaching out to serve the consumer PC community with its state-of-the-art thermal grease COOL-SILVER™”
Unlike many outfits, AIT supplies a lot of information about their Cool Silver product. (You can view all the info on their website HERE
.) Let's just clarify a few points before we move on. So, what is a “thixotropic paste?” Well, it's a substance that, when at rest behaves more like a solid, but which flows like a liquid when a lateral force is applied. In this case, the Cool Silver will flow easily over the heatsink/heatspreader interface when pressure is applied, providing a thin even film. The paste will then set up, or gel, keeping the paste where it belongs. These are very desirable characteristics for a product like this, and this property is not exclusive to Cool Silver. AIT lists this product with a micronized silver content of more than 90%. How much more, we don't know.
The other specifications are fairly difficult to briefly summarize, and require a level of technical knowledge that most folks (including myself) don't have. Suffice it to say that these specs right in the same ballpark of other quality TIMs on the market. One thing that many people find desirable in a product like this is electrical conductivity; or more precisely, the lack thereof. While AIT promises “negligible bulk electrical conductivity,” they also state this: “Even though COOL-SILVER is not conductive in bulk, individual silver particles may be conductive. Spreading to exposed circuit traces should be avoided.” The Arctic Silver 5 website carries a similar warning, but AIT provides no electrical capacitance information. So, keep it on the chip and off the board.
AIT also provides clear instructions as to how Cool Silver is to be applied, and some performance data that promises a 2C drop in temps when compared to “best among competition.” I think we can all figure out whom they mean.
PRODUCT PICTORIAL AND WALKTHROUGH
The retail packaging is sturdy, yet easy to access and the rear of the cardboard insert features a performance graph and application instructions, with visual aids. Inside is a syringe containing 3.5 grams of the silver stuff, and the plunger must be inserted into the main body before use. This is probably for packaging compactness, as the syringe and plunger is quite long when assembled. An orange cap keeps the Cool Silver inside the syringe during storage and handling.
