3 to 12 degrees centigrade lower CPU full load core temperatures than standard thermal compounds or thermal pads when measured with a calibrated thermal diode imbedded in the CPU core.
Arctic Silver 5 is sold in 3.5 gram and 12 gram tubes. The 3.5 gram tube contains enough compound to cover at least 15 to 25 small CPU cores, or 6 to 10 large CPU cores, or 2 to 5 heat plates. At a layer 0.003" thick, the 3.5 gram tube will cover approximately 16 square inches.
And the extra couple of "bucks" you spend on Arctic Silver 5 is worth it.
Ah, lies, damn lies and statistics. Sam Clemens had it right.
Arctic Silver 3
Thermal Resistance: <0.005°C-in²/Watt (0.001 inch layer)
Arctic Silver 5
Thermal Resistance: <0.0045°C-in²/Watt (0.001 inch layer)
That is a whopping big .0005 °C-in²/Watt improvement.
With a typical high performance CPU running 70 W you will see a whopping big heat reduction of:
(.0005 °C-in²/Watt x 70 W) / 0.1875 in² = 0.18 °C
This is even less than I expected.
So, for a 130% INCREASE in COST you get (assuming, as an example, an initial CPU to ambient temperature rise of 18°C rise using Arctic 3 and a very good heatsink ~0.35°C/W) a WHOPPING 1% reduction in temperature rise.
WOW, I'm impressed. That's the kind of math that gets us $500 hammers and $1000 toilet seats.
LeeJend Moto: Glitter and spangles were created by marketing to distract the consumer from reality. DO THE MATH! Read the fine print. Challenge the bastards at ever turn.
Note that in the Arctic silver literature they claim no improvement between Acrtic 3 and 5 compared to "standard thermal compounds". Both say 3-12 degrees C. Marketing pure marketing.
well a lot of cpus pump around 90w dont they?
my proc @ 1.6vcore (mobo automatically overvolts to that.. erg.)
and 3200mhz, in theory, puts out like 100W... (there was this program to
calculate it... but i think it's based on like its stock wattage and vcore inc, etc...)
so like in theory again, you can actually save like 0.2C!! omg!
Nothing on the market pumps 90W. The new Intel stuff was going to be about 100 but they decided there needed to be new PS standards and better cooling solutions so they scraped the product line and are working on a new line using the cooler technology based on their mobile processor line.
And even if it a processor pumps 150W arctic silver 5 is still waste of money at a 0.4 deg C reduction. Marketing, pure marketing.
