Thermal Compound

Arctic Silver 5 High-Density Polysynthetic Silver 3.5g Thermal Paste

( 4.8 Average / 290 Ratings )



Arctic Silver


5 High-Density Polysynthetic Silver

Part #





Three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer.
Contains over 88% thermally conductive filler by weight.These thermally-enhanced ceramic particles improve the compound's performance and long-term stability
Ensure the best physical contact between the heatsink and the CPU core.
Will not separate, run, migrate, or bleed.


Average Particle Size: <0.49 micron <0.000020 inch
Extended Temperature Limits: Peak: -50 Degrees C to >180 Degrees C
Long-Term: -50 Degrees C to 130 Degrees C
Performance: 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.
Coverage Area: A 3.5 gram syringe 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 syringe will cover approximately 16 square inches.

Do I even need to say anything about this... simply the best paste possible


from completed build Senbonzakura

Best thermal paste.

highly recommend , get the job done of course

Don't use stock paste if you are gonna even think about overclocking.

from completed build 3rd PC Build - MightyByte

Good enough for me.

from completed build The Screamer Mk-1

I heard good things about this thermal compound, and it's pretty good for the money, though it does have a lengthy break-in time.

from completed build ROG & Corsair

Great quality, great price. If you want better cooling performance, don't hesitate taking the included thermal compound off and replacing it with this. It bringed the temperature down by 3°C.

I do think that this is the best investment to make if you care about price/performance or sheer performance. Luckily I think I managed to get a good application from the first try. Pea size folks. It's not a 10 core Xeon, so even 3/4 of a pea will do. Less is more. You really need tiny amounts to cover the die, once the heatsink has squished it all. I didn't spread or anything. I don't think a credit card is smoother than the heatsink. I'm just leaving myself open to air bubbles, which have adverse effects on temps.

Does what it needs to.
