私の友人のコンピュータはこのようなことを始めましたが、彼はラップトップとして使用せずにテレビに固定されています。顕著にほこりが多く、CPU温度を90〜95Cの範囲に保つのに苦労しました。その人は以前にほこりを吹き飛ばしたことがあり、注入されないほど涼しく保たれたので、彼の場合はそれが解決策であると確信しています。
古いスレッドを破壊していることはわかっていますが、このような場合は冷却システムにほこりがある可能性があります。あるいは、システムは設計上十分にクールではありません（一部のベンダーは、ファンが必要なCPUに対してファンなしの設定を好むように見えるか、温度が十分に高くなって速度がわずかに速くなるとファンを低く保つようです）。 .)
