Arctic Alumina Thermal CompoundFormer staff writer - November 8, 2001
Arctic Silver has a brand new thermal product on the market, Arctic Alumina. Arctic Alumina is the first ceramic-based, polysynthetic thermal compound. It is made of a composite of aluminum oxide and boron nitride, thus earning it the name Artic "Alumina". Here is a quote from Arctic Silver's website regaurding the triple phase viscosity:
"The complex polysynthetic oils work together to provide three distinctive functional phases. As it comes from the tube, Arctic Alumina's consistency is optimized for application in a thin, even layer. During the CPU's initial use, the Arctic Alumina compound thins out slightly to enhance the filling of the microscopic valleys and insure the best physical contact between the heatsink and CPU core. Then the compound slowly thickens over the next 20 to 100 hours of use to its final consistency designed for long-term stability."
One of the things I noticed as I was applying Arctic Alumina to my cpu was, that it was a tad less "thick" than the Arctic Silver II. Another thing I noticed, that I liked, was how easily Arctic Alumina cleaned up. If you have ever used Arctic Silver II you know if any of it gets off the core of your cpu, it will leave residue of the silver. Not with Arctic Alumina though, it seems to clean right up.
I'm going to compare Arctic Alumina with Artic Silver II. In order to get the Full Load temps, I ran Seti@Home for 10mins and played some multimedia (Mp3's).
I did the test three times, and got the same results all three times.
I don't really see the difference between Arctic Silver II and Arctic Alumina. Except Arctic Alumina is less messy, and cost less. Although, AS2 seemed to perform 1 degree better. Artic Alumina is not yet avaliable, but should be by the end of this month. MSRP: $3.95 USD per tube. (Now that, I can afford).
I'd like to thank Arctic Silver for sending out this sample for us to review.
