  • Use a lint-free cloth (or coffee filter) with either isopropyl alcohol or ArctiClean Thermal Material Remover to thoroughly clean the thermal paste residue from both the CPU and GPU arms of the heat sink.

  • Once the heat sink surfaces are completely clean, use a fresh lint-free cloth or coffee filter to apply a drop of ArctiClean Thermal Surface Purifier to remove any oils and prepare the copper heat sink surfaces.

  • Do not touch the copper surface with your bare fingers, or allow any dust or debris to get on it. Even a fingerprint can be a major obstacle to thermal transfer. If you touch it accidentally, re-clean it and re-apply the surface purifier.

  • Allow the heat sink to dry completely while you continue working.

使用不起毛的布（或咖啡过滤器）和异丙醇或 ArctiClean 导热材料去除剂彻底清洁散热器 CPU 和 GPU 臂上的导热膏残留物。

散热器表面完全清洁后，使用新鲜的无绒布或咖啡过滤器滴上一滴 ArctiClean 导热表面净化剂，以去除任何油脂并准备铜散热器表面。

请勿用手触摸铜表面，或让任何灰尘或碎屑沾在其上。 即使是指纹也可能成为热转印的主要障碍。 如果不小心触碰，请重新清洁并重新涂抹表面净化剂。

等到散热器完全干燥后再继续工作。
