Application of thermal paste is essential to keep the processor cool and happy. Follow this general guide to reapply thermal paste after removing a heat sink or CPU during a repair. For more advanced directions, specific to your CPU, check out Arctic Silver's page of application methods.

  1. Thermal paste is responsible for conducting heat from the processor to the heat sink. Reassembling a computer without applying thermal paste will cause the processor to overheat, resulting in permanent damage.
    • Thermal paste is responsible for conducting heat from the processor to the heat sink. Reassembling a computer without applying thermal paste will cause the processor to overheat, resulting in permanent damage.

    • Before applying a new layer of thermal paste, you must first remove any old thermal paste from both the processor surface and the heat sink.

  2. Use the flat end of a spudger to scrape off as much solidified thermal paste from the copper core(s) of the heat sink as possible. Use the flat end of a spudger to scrape off as much solidified thermal paste from the copper core(s) of the heat sink as possible.

  3. After scraping off the solidified thermal paste, a residue is still present on the copper core(s).

  5. Use a coffee filter or a lint-free cloth with a drop of ArctiClean Thermal Material Remover to clean the thermal paste residue off the thermal contact surface of your heat sink. Once the surface is clean, use a new coffee filter or cloth to apply a drop of ArctiClean Thermal Surface Purifier to remove any oils and prepare the surface.

    • Once the surface is clean, use a new coffee filter or cloth to apply a drop of ArctiClean Thermal Surface Purifier to remove any oils and prepare the surface.

    • Do not touch either the chip or the heatsink, or allow any dust or debris to get on them. Even a fingerprint can be a major obstacle to thermal transfer on a chip.

    • Allow the heat sink(s) to dry completely!

  6. Use the flat end of a plastic spudger to remove any solidified thermal paste from the surface of the processor(s).
    • Use the flat end of a plastic spudger to remove any solidified thermal paste from the surface of the processor(s).

    • Do not use any metal objects for this procedure. Be careful not to break any components on the processor's surface, or get any thermal compound loose on any components (conductive pastes could cause problems).

  7. Again, use a coffee filter or lint-free cloth and a drop of ArctiClean Thermal Material Remover to clean any thermal paste residue off the processor surface. Use a new coffee filter or cloth to apply a drop of ArctiClean Thermal Surface Purifier to remove any oils and prepare the surface.

    • Allow the processor(s) to dry completely!

  8. To apply new thermal paste, use the application method recommended for your specific processor type—vertical line, horizontal line, middle dot, or surface spread.
    • To apply new thermal paste, use the application method recommended for your specific processor type—vertical line, horizontal line, middle dot, or surface spread.

    • If you're using the surface spread method:

    • Wrap the tip of your index finger with a piece of plastic (such as a sandwich bag or Saran wrap).

    • Dispense a very small amount of thermal paste onto processor core(s).

    • Use your finger to gently smear the thermal paste over the entire processor core(s).

    • If you accidentally apply a small amount of thermal paste on the green surface of the processor, it will not cause any harm.

    • The processor(s) is now ready for heat sink installation.

    • You do not need to apply any thermal paste on the heat sink(s), although Arctic Silver gives instructions on "tinting" the heat sink to reduce the break-in time of the thermal compound.

For heat sinks with a spring on the screws: Wonder why there are springs on the heat sink screws? Do not over tighten them, the springs are there to help you apply the correct amount of pressure on to the CPU and GPU. If you tighten them all the way, it may not be the correct pressure! Leave maybe 1 mm of space, just before the screw stops turning. iFixit forgot to mention this important part, and also in the heat paste guide!!

This is completely untrue. The holes bored in the heat sinks are in fact a larger diameter than both the threads and the shoulder of the heat sink screws. The screws should be fully tightened (as they were from the factory) to maintain correct pressure against the processors.

I have two green lights on my xbox slim ... Should I do all of this to get rid of them? I'm not sure if they are supposed to be green. I bought my wii and remotes from a refurbishing place. I don't have the red ring of death, but I think it is from over heating.

OMG Hi -

Thank you so much for this! Have been struggling for months with CPU diode sensor reporting 262F/128C and CPU dropping to 0.8 Ghz due to Speedstep. Loosened the screws a little and the sensor is back to normal. I cannot thank you enough for this!

It didn't help my crashing MBP, NVidia bug.
