As Richard and others have noted in this and other threads, any
difference in thermal performance between _well_ _applied_, decent
quality thermal compounds is unlikely to be perceptible in practice.
Arctic Silver is good for those of us who like to "play with" our
heatsinks and/or processors, since it works well and is reasonably
easy to clean off and reapply. If you plan to assemble a
processor/heatsink combination once and run with it, you are probably
just as well off using the thermal compound that comes with the
heatsink. I would only expect replacing your thermal compound to
improve processor cooling if you know that your processor is running
significantly hotter that it used to under the same conditions (ambent
temperature, load, other heat-producing hardware in case, etc.) and
you have excluded and/or fixed all other possible causes (dust in
heatsink slots, new or moved cabling obstructing airflow, failing
processor or case fans, etc.).
The reason why I want to abandon the thermal tape is because my temps are
running 43-45C. I want to shave a few more degrees off.
Please respond to the Newsgroup, so that others may benefit from the exchange.
