  • Upon removal, the fan seems identical to the one from the previous model—but let's not be too quick to judge a fan by its cover.

  • Advanced Hydraulic Bearing

  • Hmm. Interesting. What exactly is Advanced Hydraulic Bearing? Let's find out. According to Asia Vital Components:

  • AHB "consists of a polished steel shaft, a sintered bearing and fluid lubricant." In this system there "is no contact between shaft and bearing" and thus "the bearing load is carried solely by a film of fluid lubricant."

  • AHB is best for fans that operate at a lower speed. It's better at absorbing shock and dampening vibration than traditional ball bearings, making for a quieter fan.

拆开了风扇我们发现似乎和上一代的风扇一模一样。不过肉眼我们不能确定，我们后面会详细解答

这个风扇似乎用的是超静音轴承

嗯。有意思 先进液压轴承到底是什么？让我们一探究竟。根据《亚洲重要组件》：

AHB "由抛光的钢轴、烧结轴承和流体润滑剂组成"。在这一系统中，"轴和轴承之间没有接触"，因此 "轴承载荷完全由流体润滑剂薄膜承担"。

AHB 最适合低速运转的风扇。与传统滚珠轴承相比，它能更好地吸收冲击和抑制振动，使风扇更安静。但是似乎温度很高的时候不是这样的。
