Artic Silver 3 versus 5
Is their a noticable difference in the two? Just wondering if anyone has
an opinion, TIA. -- .. |

AS5 has slightly lower thermal resistance (about 10% better). The tradeoff these guys report, is AS5 is harder to remove later - pulling on heatsink pulls the processor out of the socket. Best to warm the assembly before trying to take it apart, if you use AS5. http://www.xtremesystems.org/forums/...d.php?p=551884 Paul |

Yes, but does the slightly lower thermal resistance actually matter?
In actual tests, the difference in CPU temp. between ANY thermal compounds tested (including the "white" compounds made of silicon or zinc) was just not significant ... only about 2 or 3 degees separated the very best from the very worst. Dont' forget, the layer of thermal compound that you end up with is very thin .... about the thickness of a couple sheets of paper. With a layer that thin, even fairly great differences in thermal conductivity don't really matter all that much to the final result (CPU temperature).

I saw one website test that suggested those improvements are mostly at idle temps rather than Max Load temps. The max load temps were mostly all the same +\- 1C which is just measurement accuracy. I'm not too worried about my idle temps. |

It works but really no better than a high-quality thermal grease. For effective heat-transfer, any such compound must be applied very thinly, enough to JUST fill any voids between the device being cooled and the heatsink, the object being to have as much of the heatsink and device as possible in DIRECT contact with the grease/paste just filling all remaining air-spaces and no more. If significant grease/paste oozes out the sides after the heat-sink is clamped down, the compound has been wrongly applied. There should be just a visible trace of ooze all around the junction-area between the device and heatsink. Those who rant over the virtues of Artic Silver have probably always applied too much thermal paste. John Lewis |

John Lewis Some claim the correct way to apply is to put a grain of rice size dab on the center of the heatsink and when you clamp it down it will spread and cover the die and all will be cool. Not so. I have tested their way and the compound does not spread enough to cover the entire die area. All you need is to cover the complete die area with compound no thicker than cellophane. I bought Antec Silver 5 (thinking I was buying Artic Silver 5, though it is probably similar stuff). Their instructions also mentioned a rice grain size. But they also instructed using a clean razor blade at a steep angle to spread the stuff evenly over the top of the CPU with a thin layer. |
