Except the outlook, the more expensive heat sink will really perform better than the cheaper one? Thanks

唔理佢通風個效果點先啦,個heatsink 個表面面積咁大,散熱一定會快過表面面積細ga

其次佢個通風口,就算唔識入風,佢通風口出面既波紋,都一定散到熱ga la!
不過最重要係要睇番個heatsink 同個魔打接觸有幾多

So it means the touching area of the heat sink and motor has 紋 is better, but I see Kyosho's heat sink has no 紋 at the bottom , don't know why.

its same theory as CPU heatsink....
The larger the contact area the better effect..
same as the larger total surface area which it allows the heat to disperse faster...

heatsink 不和马达接触只和固定马达的两快片接触
