Bitmain S5 Replacement Fan

[Geiger]

I have 3 questions...

1. What is the model of the fan that comes installed by default on Bitmain's Antminer S5?
2. Where can I get this model fan?
3. Is there a different model fan that is better? (ie. Either pushes more air or pushes the same amount of air more quietly)

as the fans are the best noctua industrial, they fit well to controller S5, but they cost too much, despite being the quietest,
then there are the Delta, but there are different models, do not buy TFC1212DE, because the controller does not support them, you have to assess well in that area are, if it's hot, and temperatures are high.
for fans of the stock of bitmain not even know what brand they are, I only know that they do a lot of noise 74/76 DB,

Thank you kindly for the information but I am looking for specifics.  Current Model, Current Model CFM, Where to Purchase Current Model.

Everything that I have seen about replacing the with a different model has lead to higher temperatures.  Is this the case or have I been reading the wrong posts?

TFC1212DE Needs an external Power and can't come off that riser on the control board as its a 4amp fan... but it also pushes 255Cubic Feet/Min

you can try these fans for me it works well


http://www.amazon.com/gp/product/B00A460TK6?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00  as pull this one as push http://www.amazon.com/gp/product/B004Y1HLA8?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00



so far on hot day here i don't go over 59 C per blade at defaults i really don't OC so don't know how it would handle it. and the sound is not to bad you can actually sleep in the same room with those fans on one S 5.



THere right i have one of the  TFC1212DE the S5 can't power it up but the one i linked they do Np and usually run at 2700 RPMS or lower depending you surrounding hottest Ive seen  one blade get was 60 C but I fixed that i blow out the fins with a wet.dry vac and re pasted all the broads which dropped all my S 5 at least 2 to 3 degrees each . but not every one get the same results.

Hello

I have this fans

Silverstone Tek 140mm x 38mm Fan for CPU Cooler and Computer Cases Cooling FHP-141

but Antminer on 350 mhz have the 75-78C temeperature
More overclocking is impossible

but the sound is much less
but the room quickly heated as the air coming out is much hotter

140mm just means you're sending more air around the heatsink, not through it.
If your thermistor reads 75-78°C I can promise you that the chips at the back of your miner are at 95°C or hotter.

Vorta, did you do any fan mods?@

if you look at what i posted i also use a delta fan with 151  CFM as push i wouldn't use the Silverstone alone or it will get hot fast and I use the Silverstone on the P setting not Q .

I believe the one that comes with S5 is around 4000 RPM.   That fan appears to be around 2000 RPM.  It's essentially cutting your cooling from fan in half.

If your wanting to do less on fan you really need to do a push/pull combo.   I would recommend putting on original fan till you get another of other to test push/pull.

78C is just getting pretty hot.  And pushing it pretty hard.

[Geiger]

I thought for sure that somebody would know the make/model of the OEM fan.  Sounds like it is a variable speed 4,000 RPM 120mm fan but without the specifics I'm not sure if a replacement is good/better/worse.

NO Sir NOT AT ALL, IT DEPENDS ON BLAE PITCH... A 200RPM fan could be moving MORE air based on the blade pitch....

Please don't spout off about things you have no clue about.

UNLESS This is the fan:

http://www.amazon.com/Koolance-FAN-12038HBK-184-Fan-120x38mm-184CFM/dp/B0050UP8HK


Then we are talking ~180CFM.... but these would make the S5 as loud as a room full of people talking (As loud as an S4/S4+)


Can you get me any information Off the Physical fan? I know its a 12038

From a previous discussion, this was said to be the stock fan specs:

Dimension: 120*120*38mm
Voltage: 12V
Start voltage: ≧8V (Power ON/OFF)
Power consumption: 1600RPM 1.68W / 4000RPM 25.8W
Rated current: DutyCycle 100% @ 2.15A
Air Flow: 4000RPM @ 178.3CFM (Max be 239CFM)
Noise: 4000RPM @ 56.7 dB-A (Measured in a Non-EchoChamber)
Life Expectancy: 40,000 hrs @ 25℃  (May degrade faster at higher temperature)
Connector: 2510-4P

Also, I recently tried a dual 60CFM fan setup (one for push, one for pull), but it was clearly not powerful enough - temps were at 70C within a few minutes. This is what I used:

http://www.newegg.com/Product/Product.aspx?Item=N82E16835553008

I just ordered the following Delta and am hoping I can use it alone for just push:

Delta Electronics AFB1212SHE 120x120x38mm Cooling Fan, 151.85 CFM, 58 dBA, 3700 RPM, 1.06 AMP, PWM 4-pin connector.

I have the miners running in a temp controlled room with proper ventilation, which helps the temp's, but I'm still worried if the Delta might not be enough as 2x 60CFM was clearly not even close.

Max be 239CFM  That's very close to my Big boy deltas I use to cool my radiator for my OC i7 3930k~ 4.7ghz.....

Whats the Air Pressure?    My delta at 252CFM is: 1.412 IN H2O 35.877 mmH2O

Yup, that's exactly what I ordered from amazon - arrives on Monday. On the stock fan I'm running at 48-59C for a 350-400 frequency. The room ambient temp is kept at 21C. If I can stay under 65C with the Delta I'll be very happy. I know it pushes less CFM than the stock fan, but hopefully it does enough.

I believe that's the physical hardware max. At 4,000 rpm (the most I've seen the fan spin), it's 178. More here:

Get a Delta 35.877 mmH2O vs 16.9MM-H2O :p  the key in the weay we use these fans is really is the MM-H20 over the CFM.... but then again who cares as long as the machine doesn't over heat

What do you mean by "1.412 IN H2O 35.877 mmH2O".  I'm sure you make sense.  It's just that I know the lingo.
