Conclusion: Arctic Silver 5 is an unique high-density filling of micronized silver and enhanced thermally conductive ceramic particles which provides a new level of performance and stability for thermal solutions. The price for this Arctic Silver 5 is not too expensive, only RM29 each tube (3.5grams).
Conclusion: If someone would have told me this was going to be the outcome, I would have been very skeptical. I've been floored with the performance of this stuff, to say the least. I had visions of all the crappy installations I'd seen when OEM's install the fan/heatsink combos on their videocards using...
Pros: Greater heat transfer properties than with thermal type tape, Greater strength (could be important holding on oversize or heavy heatsinks)
Cons: Permanent (although can be thinned), Must also own Arctic Silver thermal paste to thin (which effectively doubles the cost), Installation is a bit more involved than with tape, A little pricey (although a little goes a long way)
