  • The CPU will most likely be stuck to the heat sink with thermal compound.

  • Insert the flat end of a spudger between the CPU and heat sink.

  • Gently pry the CPU up by slightly twisting the spudger.

  • Remove the CPU from the heat sink. Be careful not to touch the contacts.

  • To reinstall the heat sink, see our thermal paste guide for instructions on cleaning and preparing the thermal surfaces and applying a new layer of thermal compound onto the CPU and GPU dies.

  • For the VRAM chips surrounding the GPU, install thermal pads or a thick thermal paste such as K5-PRO, rather than regular thermal paste.

  • Install your CPU into its socket on the board, not on the heat sink. Check the orientation and make sure it lines up correctly in the socket. Follow the instructions specific to your CPU type to apply fresh thermal paste to the surface of your CPU. Then, reinstall the heat sink over the top.

CPU 很可能会用导热膏粘在散热器上。

将撬棒的扁平端插入 CPU 和散热器之间。

稍微扭转撬棒，轻轻撬起 CPU。

从散热器上拆下 CPU。 小心不要触摸触点。

要重新安装散热器，请参阅我们的导热膏指南，了解有关清洁和准备导热表面以及在 CPU 和 GPU 芯片上涂抹新的导热膏层的说明。

对于 GPU 周围的 VRAM 芯片，请安装导热垫或厚导热膏（例如 K5-PRO），而不是常规导热膏。

将 CPU 安装到电路板上的插座中，而不是散热器上。检查方向，确保在插座中正确对齐。按照 CPU 类型的具体说明在 CPU 表面涂上新的散热膏。然后，在顶部重新安装散热器。
