Conclusion: I like Arctic Silver 5. It improved every so slightly but every bit counts. It’s thicker, a new color, and temperatures decreased. If you already have Arctic Silver Ceramqiue you shouldn’t upgrade to Arctic Silver 5 yet. It’s just a small difference. But once you are done with it, make sure you pick up Arctic Silver 5. It's the best yet! Bar none. It will be used in feature testing. I rate the Arctic Silver 5 a… 9.5/10!
Pros: Improved Cooling, Thicker means better, Syringe
Cons: None that I can see except the small price increase in some stores
Excerpt: A good thermal compound is just as important as a good heatsink. Originally sold as pre-applied pads, TIMs (Thermal Interface Materials) serve to fill in any space between a processor core and a corresponding heatsink. Ideally a thermal compound isn't necessary: its only purpose is to fill in microscopic gaps between the two surfaces. The more you lap (polish) a heatsink, the less compound you'll need.
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).
Summary: After applying
Arctic Silver 5, it was indeed an improvement from Arctic Silver 3. Thought some
people would use something less extreme that is not conductive at all, however,
sometimes we have to make our choices and use the best if we want to get couple
of those extra megahertz from the CPU.
Pros: Contains 99.9% pure silver, One of the best thermal compounds in the market
Cons: Still partially conductive, Takes a long time to sink in for
water cooled systems
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 thermal epoxy (it might be well worth removing and reinstalling them properly, if you could bring yourself to use the stock fan).
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)
