How much lower does Artic Silver 5 reduce CPU temp

[TOTA42]

I'm sure there is a thread like this somewhere, but I couldn't find it with the search string "arctic silver". I just recently got a new CPU fan so I decided to place some Arctic Silver 5 on it and try it out. Now the question is here, how much lower does this thermal paste reduce in temperature on your guys systems compared to using stock heatsink/fans. I couldn't find any data discussing this. I have an Intel 4 2.66 Ghz, Asus P4PE-X Mobo, and a Arctic Cooling Super Silent 4ProL cpu fan.

MB temp at idle: 31c 87f
MB temp at peak: 34c 93f

CPU idle: 43c 109f
CPU peak: 66c 150f

I haven't finished the "break-in" period, so I can understand if the temperature difference between now and with stock equipment is like nil. So what temps did you guys get to achieve on your systems?

I think the difference between a cheap thermal paste and AS5, if both are properly applied, will be 4°C at most.

I honestly think the differnce is almost negligable between the thermal pastes as far as temps go,but of more importance would be the quality/longevity of the pastes.Some pastes degrade over time wich worsens their thermal transfer capabilities.That's the main reason I go with a good,tried brand name.
Also to consider is the fact that any thermal paste must be applied correctly to perform to standards to begin with.An often overlooked,misunderstood procedure.Just browse around and you'll see failed attempts at proper cooling due to "over pasting" or air bubbles etc.
One other consideration would be the removal of said pastes when changing HSF's and reapplying pastes.Some burn in and become a PITA to remove where as others remain nice and "creamy" and merely require a decent kleenex wiping.That latter is just a fringe benefit and doesn't matter that much and to some not at all.
So I wouldn't go trying to split hairs concerning the cooling differences with the various thermal pastes out there.Like i said it's negligable.Do howeer stick with a brand name paste.Arctic Silver is great stuff.Been using it for the past couple 'puters I've built on CPU's,Chipsets,memory.In the past I've used others,usually the pre-supplied stuff that was included with certain hardware and there is a noticable difference in quality in favor of Arctic Silver.

Disclaimer: If you're a hardcore overclocker then of course every little bit helps,even if it is just a degree or 2,to maintain a reliable overclock within temp spec's.

I've also used Arctic Silver 5 and I must say it works like a charm, especially with the good cooling I have here.

CPU idle: 28 - 32 degrees C
CPU load: 42 - 44 degrees C

So owned! <3

AS5 and Cermique are about tied, however Article Silver Cermique is not conductive!

You silly man.Of course it's conductive.It conducts heat from it's source to the heatsink.

Quoted straight from the Arctic Silver website:

Introducing Arctic Silver 5. With its unique high-density filling of micronized silver and enhanced thermally
conductive ceramic particles, Arctic Silver 5 provides a new level of
performance and stability. Now available at Arctic Silver dealers worldwide, Arctic Silver 5 is definitely

And heres the link to Arctic Silver Ceramique in specific http://www.arcticsilver.com/ceramique.htm

Heres the exerpt from that last page link

<0.007°C-in2/Watt (0.001 inch layer)

Thermal Conductance:
>200,000W/m2.°C (0.001 inch layer)

Average Particle Size:
<0.38 microns <0.000015 inch
( 67 particles lined up in a row equal 1/1000th of an inch. )

Temperature limits:
Peak: ?150°C to >180°C Long-Term: ?150°C to 125°C

Coverage Area:
2.5-gram syringes. (About 1cc)
At a layer 0.003" thick, one tube will cover approximately 20 square inches.

22-gram syringes. (About 8cc)
At a layer 0.003" thick, one tube will cover approximately 160 square inches.

Important Reminder:

Due to the unique shapes and sizes of the particles in Ceramique, it will take a minimum of 25 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop slightly over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

Got a 3C drop in temps with AS5. I've been hearing that the thermal tape on the A64's will glue the heatsink to the cpu and it's best to replace it right away. Anyone know about this?
