2015-4 Bitcoin mining Antminer S5 Rebuilt

Bitmain posting P62 Antminer S5

replacing the stock fan with a single Noctua ($24.5 on Amazon) makes it much less loud and changes the metallic banging sound of the stock fan to whooosh, although temperatures rise to ~60C and you have to hash at 325 mhz(1075 GH). I am waiting for a second fan to add pull and go back to 350mhz or even higher.

Here's my experience with the 2 S5's (batch 2) I received yesterday.  Got it unpacked and hooked up and turned on I thought "Oh, hell no!"  No way those fans can make this a home miner unless you're talking about keeping them in the Silence of the Lambs basement.  Switched to the Silverstone 141 fans on performance mode (1,920RPM is a loud woosh over the scream of the OEM fan) and put them in the back in a pull setup.  Turned on and they quickly shot up to 79 degrees Celsius, tried at 312.5M and they stayed at 79.  Turned them off and moved the fans to the front (fits fine if you use a bootless network cable) in a push setup, turned them on and they started going up past 70 again, so set the miners at 312.5M and waited.  They settled at 70-74 degrees C according to GUI, in a room that's about 75-80 degree F with 0 HW errors.  I can handle that, each is hashing about (1,025 GH/s avg.) that's about what my C1 did (1,005 GH/s avg.).  Need to get some readings with the Kill-A-Watt today to see how much power it's drawing at 2 x 312.5M.

I bought the Delta AFB1212SHE units in bulk. Also have the Noctura Fans but will test and send back if the Deltas cut it.

2015-3 穷爸爸富爸爸笔记

乞丐立即走过来，他收了钱，含糊不清地道了

谢就欣喜若狂地拿着他的钱走了。

“他与我的大多数雇员并没有太大差别，”富

爸爸说，“我遇到过很多人，他们说‘我对钱

没兴趣’，可他们却一天工作8 小时并不停地

抱怨工作无聊。如果他们对钱没兴趣，又何必

干自己不喜欢的工作呢？这种人比敛财的人

病得更重。”

你看，我们最终都是雇员，只不过处于不同

层次而且。我只希望孩子们有机会避开由恐惧

和欲望组成的陷讲，能按你喜爱的方式选用恐

惧和欲望，别让恐惧和欲望控制你。

这就是我想教你们的。我对教你们如何挣大把

的钱没有兴趣，那解决不了问题。如果你们不

先控制恐惧和欲望，即使你们有钱，也只不过

是高薪的奴隶而已。

学会让感情跟随你的思想，而不要让思想跟

着你的感情。

工作只是面对长期问题的一种暂时的解决办法。

大多数人心里只有一

个问题，并且是短期的，那就是月末要付账了，

于是又感到恐惧了。钱控制了他们的生活，或

者说对钱的无知或恐惧控制了他们的生活。所

以他们就像他们的父母一样生活，早早起来去

工作挣钱，而从不抽时间问问，有什么别的法

子吗？他们的思想由他们的感情控制着的，而

不是他们的头脑。”

要知道讨厌失败和害怕失败之间有着

巨大的差异，大部分人因为太害怕失败而失

败，他们甚至会因一幢两套房的复式公寓而完

全破产，财务上他们做得过于安全。

规模太小，他们买大房子、大轿车，却不去做

大的投资。90％的美国公众财务困难的主要原

因就在于他们是为了避免损失而理财，而不是为了赢利而理财。
