いま，Raspberry Pi 3 Model B+(RPi3+)は，アマゾンの出店者から買ったヒートシンク一体型のケースを使用しています．ファンの付いてないパッシブな冷却です．<\/p>\n\n\n\n

CPUの温度が50℃くらいの時，ケースの温度は40℃くらいです．<\/p>\n\n\n

パッシブなヒートシンク一体型ケースのメリットとしては，<\/p>\n\n\n\n

  • 確実に冷える<\/li>
  • ファンなどの故障によるオーバーヒートの心配がない<\/li><\/ul>\n\n\n\n

    等が主なところです．逆にデメリットは，<\/p>\n\n\n\n

    • Wi-FiもBluetoothも弱い<\/li><\/ul>\n\n\n\n

      です．全体をアルミで囲っているわけですから，当然と言えば当然です．Wi-Fiルーターの近くでいじることが多いので，ネット接続のほうは問題にはなりませんが，Bluetoothはキーボードがしばしば切断してしまいかなり支障をきたしています．<\/p>\n\n\n\n

      また，ケースを触ったとき，思ったより暖かいのになかなか慣れません．冬だと気持ちいいのかもしれません．<\/p>\n\n\n\n

      そんなこんなで，冷却装置を見直し中のRaspberry Pi 3 Model B (RPi3)のほうは，樹脂製のケースに大きな穴が開いていてファンで排気するオーソドックスな空冷ケースを購入することにしました．発熱するチップにはそれぞれおもちゃみたいなヒートシンクを貼り付けます．<\/p>\n\n\n\n

      お盆休みを挟んでしまったので，到着するのが1週間ほど先になりました．<\/p>\n","protected":false},"excerpt":{"rendered":"
