Changing the thermal paste

  • Disconnecting the battery is highly recommended.

  • Unscrew the 4 screws holding the CPU heatsink and disconnect the fan.

  • Clean the old thermal paste from both the cooler and the CPU.

  • Use isopropyl alcohol and cotton swabs or paper towel, but be careful not to press too hard on the CPU.

  • It's also recommended to use compressed air to remove any dust in the laptop and the fan.

  • Use only enough thermal paste to cover a portion of the pad. Use a spreader if you have one.

  • The thermal paste will apply evenly after you tighten the heatsink.

  • Place the heatsink back into the unit carefully and tighten the screws in an "X" pattern to ensure even pressure. Don't forget to plug in the fan cable.

放熱グリスを交換

バッテリーを外しておくことをお勧めします。

CPUヒートシンクを固定しているネジ4本を外し、ファンを外します。

古い放熱グリスをクーラーとCPUの両方から掃除します。イソプロピルアルコールと綿棒やペーパータオルを使うのがベストですが、CPUにはあまり強く当てないように注意してください。

またエアコンプレッサーでノートパソコンやファンのホコリを取り除くのもおすすめです。

グリスはあまり多く使わず、パッドの一部を覆う程度にします。スプレッダーをお持ちの場合は、それを使用してください。ヒートシンクを締め付けると、サーマルペーストが均一に塗布されます。

最後に、ヒートシンクを慎重に戻し、圧力が均一になるように1→4の順でネジを締めます。ファンケーブルを接続するのを忘れないでください。
