  • From the manufacturer


    Thermal Paste

    Features

    • Made With 99.9% Pure Silver: Arctic Silver 5 uses three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer.

    Arctic Silver 5 AS5-3.5G Thermal Paste

    Thermal Paste

    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. Available at Arctic Silver resellers worldwide. Arctic Silver 5 is the reference premium thermal compound. Arctic Silver 5 is optimized for a wide range of bond lines between modern high-power CPUs and high performance heatsinks or water-cooling solutions.

    Arctic Silver 5 contains over 88% thermally conductive filler by weight. In addition to micronized silver, Arctic Silver 5 also contains sub-micron zinc oxide, aluminum oxide and boron nitride particles.

    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.

    Controlled Triple-Phase Viscosity

    Arctic Silver 5 does not contain any silicone. The suspension fluid is a proprietary mixture of advanced polysynthetic oils that work together to provide three distinctive functional phases. As it comes from the syringe, Arctic Silver 5's consistency is engineered for easy application. During the CPU's initial use, the compound thins out to enhance the filling of the microscopic valleys and ensure the best physical contact between the heatsink and the CPU core. Then the compound thickens slightly over the next 50 to 200 hours of use to its final consistency designed for long-term stability. (This should not be confused with conventional phase change pads that are pre-attached to many heatsinks. Those pads melt each time they get hot then re-solidify when they cool.

    The viscosity changes that Arctic Silver 5 goes through are much more subtle and ultimately much more effective.)

    Transfers heat away
    This stuff works very well. The T.F.I. module on my 1989 5.0 V8 F150 stays cooler now. Ford initially mounted the TFI module on the distributor housing. Not a great environment as that area of the engine stays hot during engine operation. No more ignition stumbling. I believe the paste is transferring the heat away from the module a lot better than other products out there.

    5.0 out of 5 stars Funcionou perfeitamente.
    Reviewed in Brazil on August 6, 2023
    O meu notebook Dell Vostro 3400 de 2012 estava superaquecendo e desligando ao participar de reuniões no Zoom e no Meet. Foi a primeira manutenção desse tipo e essa pasta térmica funcionou perfeitamente. Já fiz o teste em uma reunião no Zoom e notebook conseguiu dissipar o calor. Fiz teste com um jogo também e o notebook manteve uma temperatura baixa em relação à que vinha alcançando antes da troca. A entrega foi feita dentro do prazo e o produto foi embalado conforme a imagem (sem a moeda). Fiz aplicação no CPU e GPU e sobrou pasta. Porém, as unidades de processamento desse notebook (velho) tem uma superfície pequena para cobrir. Além disse, tentei evitar colocar em excesso para não perder pasta pelas laterais com a pressão do dissipador.

    5.0 out of 5 stars Just Go For It- Wont be disappointed! Its AS5
    Reviewed in India on December 7, 2018
    Arctic Silver- Age old name & professionals choice for any high end machine. Had its name in mind since years. So when the need came ordered one.

    Product comes in open poly packaging. There is neither any blister pack nor any seal. Appears like product is imported in bulk & then sold in loose packaging. Only a Zip lock poly bag with a syringe containing 3.5 AS5 compund.
    But it appears genuine & performs well.

    *******
    PROS
    *******
    1. Its old & trusted name in thermal paste world
    2. Will bring down temperatures by 10-20 degrees. More important is system will be stable under load & run for longer durations at higher frequencies.
    3. Qty is also good. If applied in right qty without wastage, it may last for approx 4-5 repaste jobs, on cpu & gpu.

    *******
    CONS
    *******
    Only con being, though not electrically conductive its slightly capacitive, and if not applied carefully, will spread outside to small components on die & create trouble.

    **********************
    USAGE SCENARIO
    **********************
    I used it in my old Dell XPS L502x & Inspiron 15R (all stats are wrt xps one), to replace stock thermal paste on CPU & GPU.
    CPU throttling due to excess core temperatures 95 Deg + on load. On even small load, it shooted up to 100 & then throttling will occur.
    High temp were due to dust accumulation on vents, fin & old expired thermal paste.

    ***********
    HOW TO
    ***********
    1. Using cleaning solution (eg isopropyl alcohol available at chemist shop) & swab, clean out old paste. Be careful. Clean dies to mirror finish.
    2. On square die, apply a drop. Neither too big, nor too small. Will depend on die size & your guess. On rectangular die, apply a line. When heatsink is pressed on to die, due to pressure it auto spreads consistently. Its preferred method, i did not go for spread method as it may sometimes leave air bubbles which is a no go.

    *pic attached with illustration on square/rectangular die & real application on rectangular die

    **************************
    BEFORE APPLICATION
    **************************
    Cold boot, no apps running, core temp was 63 Deg, CPU at 800mhz
    On full load via prime 95
    After 2 min 95 deg & cpu at 1700mhz
    After 5 mins 95 deg & cpu at 1500mhz
    After 15 mins 95 deg & cpu at 1100mhz
    Fan: at full rpm, continuously whirring.

    ************************
    AFTER APPLICATION
    ************************
    Cold boot, no apps running, after 15 mins core temp was 50 Deg, CPU at 2400mhz
    On full load via prime 95
    After 2 min 79 deg & cpu at 2900mhz
    After 5 mins 82 deg & cpu at 2700mhz
    After 15 mins 82 deg & cpu at 2600mhz
    Fan: less noise and triggers less. Very lesso n high rpm

    So it appears like, huge difference in performance & power saving!! Its been a few days after application, n laptop seems to run cool & there is visible boost in performace on load.

    ******************
    FINAL VERDICT
    ******************
    So getting AS5 was not a bad investment! You can surely go for it. Just be careful in its application as though not electrically conductive, its capacitive & if not used in desired qty may spread out to small components on die & create trouble.

    Also be patient after application as it takes around 200 hours to cure or to reach its full capacity. Thats burn in time for AS5.
