根據內文可知道:
一拆發現使用的風扇,不是包裝上主打的HDB fan

Here's the fan of the day. Wait... isn't this a sleeve bearing fan? Weren't we promised an HDB fan by the box? What gives, Coolermaster?
另外電路板焊接有夠糟

Now that's just ugly, but I reckon it was either do this or engineer a double layer PCB. Enhance's board work is usually top notch, but not this time.
不知道這是整批都這樣還是個案,有這顆的來拆拆看吧(雖然拆了就沒保固了)
