Upgrade Antminer s5 fan for cooling?

[Chazaki]

With noise being a nonissue, can anyone recommend a fan that can replace the stock fan on the S5 to further increase cooling? Is the stock fan the best option available?

I am currently running 6 miners in a vertical setup (followed the guide found here (thanks for that!)). They are all running great now with temps around 58-60 but I'm fearful for the summer months as the ambient temperature is going to vastly increase.

Thanks in advance for the help

I have a monster fan far better then the stock one. I got it on ebay.

I have 2 and it is crazy fucking loud.  I will find the seller on ebay for you.

box of 20 use them as pull fans and keep the stock one in place.

 It will be  nut job crazy loud but that combo will cool amazing. they are pwm and they fit no wiring needed.

ps if you want my two send me a pm. I live in New Jersey

Absolutely not the best option.

You can try this non-expensive but good enough fan: Gembird DC120SF-12AS3 (120x120x38 mm, 3000 rpm, 124.74 CFM).

If in your certain environment where your S5(s) is(are) placed the air temperature is not low enough, you can try two of them in push-pull configuration, because even two of them are significantly quieter then the stock fan.

 he said sound has no meaning for his  setup.

the fans I pointed to create   tremendous air pressure. they will do the job far better then your pick.  your pick is quiet.

@ op am I reading you correctly sound is not an issue?  cooling is the issue?

then get something like mine.  better yet  do this test.  turn off 1 of your s-5's pull the fan and use 2 stock fans as push pull see what they do. 

they whale and work well by my tests.

Correct sound is no issue, I am trying to get them as cool as possible as I live in Texas and the summer months get pretty toasty. My mining rigs are in my non air conditioned garage. Will most likely add a small air conditioner anyway as I like to work on my cars and such. FWIW I am only really mining for hobby.

Thanks for the advice on those fans I'll absolutely have a check. I put a box fan on top of the six fans to act as a pull but I don't think the fan was powerful enough and had an adverse effect. I am curious to see if individual fans in a push pull setup would work better

Just to chime in with what I've learned as I've been searching and planning to do the same thing. Came here for some advice as tomorrow gonna be fun!

From Dogie and others, high static pressure is what is really important with these fans, more so than CFM. Fan write ups SP120 High Static Pressure echo the recommendation that the static pressure is most important for radiator/heat sink type applications. Another thought would be to get a 80mm to 120mm shroud, put in an 80mm jet fan and see what happens.

Tomorrow have a 1300G2 Supernova and 2x Corsair SP120 High Static Pressure fans coming. Can't wait.

well having done loud fans. and many combo's of fans with  the s-5.

 2 stock fans  as push-pull are very good. one of the best cooling setups you can do.

the delta as a push and the stock as a pull is very good.

the ones I list above that I found on ebay are better use the stock as a push and the ebay fan as a  pull.  you will be louder then 80db but they will cool off really well.

Since noise is a factor I run the delta as a push and the silverstone 141 as a pull.

 I also use a rubber mat under the s-5 so it has a tight seal under the unit air goes upwards a bit which is okay as  most of that air passes right through the heatsink due to the push pull.

At 368 clock I have 99.9999 correct. 14 errors out of 25 mill.  this is pretty much a perfect setup.  sound is at 55db vs 75db  watts are around 600 at the kwatt meter.
