Important Notes on Usage

• Cooler Compatibility :

  • The AM5 High Performance Heatspreader is 2 mm thinner than the stock heatspreader. Ensure that your CPU cooler’s mounting kit allows for a deeper installation.

  • If adjustments are needed, consider using the AM5 Adapter & Offset Mounting Kit for compatibility.

• Nickel Plating Update (Post-August 2024) :

  • The nickel plating process was updated in August 2024. New units may appear slightly duller, with visible copper due to a thinner nickel layer. However, this improves thermal conductivity by up to 5°C .
