What fan has the lowest dBA fan with acceptable CFM?

What MINER has the lowest PRICE without needing to mod a fan with acceptable PRICE & without the FALSE/MISLEADING advert ?

should be the proper question. let's see what the dawg says

What car has the highest Horsepower with acceptable price...

Sounds like a retarded question...

What I can't get over, as other are stating, is why is there no top or bottom? The cheap plastic sides are bad enough. Why couldn't you provide a plastic top and bottom.

I can't directly answer your question, but I've tested closing top and bottom off. It moves temps ~1.5C, not record breaking, and that's SEALED top and bottom rather than more plates which won't seal.

I have ordered my first S5. Got to see how mining works with them. I have been mining with GPUs now for over a year.

Do you think it is more profitable to switch from GPU mining to ASIC mining via Antminer S5 for example? I don't have to pay for electricity anyways.
Therefore I could sell my GPUs (6x R9 280x and 3x r9 290) and switch them for ASICs. But lately GPU mining is dieing so hard. It was fun early, when coinlaunches were made. But there are so less coinlaunches in last time because of all the scams. The cards have been running on Nicehash since over 2-3 months now.

I would have thought that you're losing more in GPU depreciation than you're mining, surely? What coin are you on?

I have been running them on Nicehash lately. But as I meantioned, I don't have to pay for electricity at the moment. But the circuits are limited, I actually don't know how much I can after all plug into the wall 

I couldn't find out now at all which were good fans to hook up on the S5s to keep them more quiet. And can I power 2 S5s with one EVGA Supernova 1300, or even with a Corsair Platimax 1200i? http://www.corsair.com/en-us/ax1200i-digital-atx-power-supply-1200-watt-80-plus-platinum-certified-fully-modular-psu

Yes you can run 2 S5 off of 1 EVGA 1300W Gold Supernova. The 2 S5 at factory 350MHZ pulls about 1200W at the wall. I would not recommend the Corsair 1200W simply because the cost difference is not worth it $310 Corsair vs $170 EVGA 1300W. The efficiency difference between Gold and Platinum PSUs is slim, and you would probably end up getting the same efficiency because the Corsair would be at 100% load, where the EVGA would only be at a 90% load. Also you have zero room for overclocking on the Corsair and you might even need to underclock to fit both.

I have smaller fans on mine and they pull together, 1170W at the wall. I'm running 120mm Delta replacement fans that push about 150 CFM.

Thank you for your response.
I'm selling my GPUs already, some have been even sold. But somehow I'm a little bit afraid to switch all into Antminers. I somehow got used to my GPUs but seems that era ended for me . As I stated there is no electricity costs for me. And right now I do own 2 EVGA 1300 SuperNOVA and also the Corsair AX1200i. I don't have to buy them anymore. Did you have room to overclock your S5s with the EVGA? For the Corsair I guess this is what will be the problem. Guess I will have to underclock. But first I will run about 4 S5s. All powered by the EVGAs. Eventually I'll get a 5th, which will be hooked onto the Corsair and maybe a 6th one will follow. But that depends. Maybe next month or later, and if it will be still worthy then is the other question. My main concern is just about the noise. Did anybody measure decibels on the s5s? Right now even my 290s go up to 70 db. Guess sooner or later I will have to swap the fans on the S5s.

From personal experience you will not be able to run (2) S5 units in overclock on a single 1300 G2. I own both 1300s and the 1200xi as well.

Some options to consider would be to pair the the 1300 with a 850; and run the 2 PSUs to run 3 miners. Then overclock to your circuit breakers limits.

I'm running 2 - S5 at 362.5 off a single EVGA 1300 both averaging about 1.195 TH/s over the last 5 days.  Potential caveat: the 1300 is attached to 240v and the S5's are sitting at about 4 Celsius ambient.

I have an S5 that I received last week that has a dead blade. What's the best way to RMA it? I'm located in the US.

If you bought it from Bitmain they will warranty it. If you bought it from a reseller you have to go back to the reseller.

Yeah, got it straight from Bitmain China. I sent their support an email, hope to hear back soon.

Did you try to switch to a different port on the control board? I read somewhere that switching to a different port on the control board fix a dead board.

You can usually get a quicker response for US RMAs if you PM BitmainWarranty to arrange an RMA. Be sure to link to your post describing the issues, what type and how many miners you wish to have repaired/replaced and your bitmaintech.com order number. Via the ticket system it has to worm its way one more step to an agent who is in the US. The BitmainWarranty team is mostly US so they're quicker.

Many other users are running 2x S5s off a 1300 G2. Its not even 80% load?

In fact I've actually managed to run 2x S5's not overclocked off the 1000 watt variant(not long term) without an issue(EVGA PSUs put out more watts than they are rated for), the 1300 should work fine for two and has a little headroom for overlock.

Thanks, I tried the other port on the controller but that didn't help. Sometimes the Blade comes up after a reboot but only shows half O's and the hash rate is still about half the normal rate. I PM'd BitmainWarranty to see if they can help out too.

@727miner,

We got your message!  Please submit a ticket via a link in the PM so we can even more expedite for you!

Sorry for the trouble.


PS: the url in the PM is a different ticket system that speed things up a bit.  It goes direct to our tech staffs around the world who are linked back to US & EU Operations.

Can you load balance on these again?  My brother wants to buy half a miner with me, and we want to make sure we can split the hashrate 50/50 to both of our pools, also any other variation split 40/60 and/or 30/70?

Thanks,

DebitMe

Call me worried but, I think I have found a setting that gets me a decent hash rate with temps below 60c. 300 with the current set up that I have will yield 59 and 57 degrees on the blades but within the first hour or so I get 1 hardware error and over the course of a day and a half (36hours) I have 12 hardware errors. Now, I am powering this miner with a high quality 80 gold 650watt power supply.

first of all, are 12 hardware errors over the course of 36 hours ok for the miner? does that seem a bit high? I suppose the cooler I get the less likely the hardware errors will be produced. I am getting two new noctua nf-f12 fans, one at 3000rpm (push) and one at 2000rpm (pull) to replace my current setup as the wife has finally said the miner it too loud and producing too much heat.

I am asking about hardware errors again because I noticed that when I first set the miner to 300 it performed at just over 1Th/s and now it is working at just under 1Th/s. Do hardware errors effect hash rate?

The number of HW errors is not important. It's the percentage. HW errors are a GOOD thing for ASICs. It means your ASIC is being pushed to its limits for speed. Generally there is a tradeoff early on. Going from 0 to 1% HW errors results in a 5-15% increase in speed. and that takes about a hour to even out or become stable.

Future increases generally have smaller gains. Good ASIC firmware will automatically push the clocks up on ASICs to maximize the effective hash rate. but if it goes over a certain %  that is bad, for the S5 i think the safe % is 0.388 or some thing like that . mine never go over 0.02 that's  for days not mins or hours and i OC with a 750 gold psu or higher on all my S5, I'm not pushing OCing just saying even at 300 i would use a 750 or higher .


I would buy a 750 Watt psu gold . that gives you a lot of head room, but that's me. That  may even be why the high temps it's  not supplying enough power to keep it cool, when it needs it. I may be wrong . i  can't say I all ways over kill on  PSUs  not to much but just enough that it's not a waste .

How did you calculate the number? 0.388% of what?
