NanoPiの記事とても参考になります。
NanoPiNeo(H3のほう)で高負荷の実験をしたのですが、1.2GHzだとヒートシンクがあるにもかかわらず、すぐに70度を超えてリミッターに当たるようで、クロックが下げられ、温度が下がるとまたクロックが上がり、電源の電流計でみていると数秒毎に消費電流がふらつく動作をします。
ヒートシンクにドライヤーで冷風を当てると40度くらいで安定して1.2GHz動作しました。
高負荷で動かすには小さいCPUクーラーが必要なようです。
今はNeo2(H5)のほうで実験中です。
ありがとうございます。
家では高負荷で動かすときは空気清浄機の吹き出し口の風がヒートシンクに当たるようにして冷やしてます。FriendlyELEC(FriendryARM)のヒートシンクはフィンがすごく小さくて見るからに冷却力が低そうですが、高負荷で動かすなら本当に冷却力が足りないのでまともなものを使う方が良さそうです。ヒートシンクだけでなく、SoCとヒートシンクの間に挟むシリコンスポンジの熱伝導パッド(放熱パッド)も高性能な熱伝導グリスやシートなどと比べると圧倒的に性能が低いので、それも使うのをやめて金属プレートのアダプタ+グリス+大型ヒートシンクが良さそうです。
でも、低負荷ならFriendlyELECのNEO用ヒートシンクでもダメじゃない。コンパクトなのが売りなんだし。
