Today I added a Delta AFC1212DE which has 148cfm at 3900 rpm which is being run through molex so it's going full speed. I also have a second fan running in a pull configuration at 1800 rpm. But for some odd reason Row 1 is 58 degrees and row two is 44. There is A LOT of air being pushed and pulled through this miner, why is one side way hotter? Should I RMA? I've only been running it for 5 days. I should also add I'm running it at the stock 350 setting. So no overclocking. Also the temperature in the garage is 58 degrees Fahrenheit / 14 degrees Celsius.
EDIT 1: It has now started restarting mining every 7 minutes or so. It will be at 1Th then all of a sudden drop to 0 and then start to climb back up. There are no X's.
As others have said, nothing wrong with the temp delta between the two boards, its quite common and a product of a not very accurate measurement system. It does what it needs to though. What power supply are you using, the controller rebooting rather than blades dropping or X'ing is rather uncommon.

Hi, I too had similar experience as quoted, however mine did not restart every 7 mins. When I first got my S5, it was working flawlessly for good 2 days. Then the hashing rate would gradually drop and eventually to 0 and restart. Its left at default freq of 350, temp was around 54 in the mornings and 56 highest during the day. Its powered by a CoolerMaster v1000 PSU which is running cool all day. I turned it off for 5 mins and started again but after running around 30 mins or so it will happen again. I have another 2 units of C1 running 24/7 which does not seems to have any problem, so I guess that rules out the internet connection possibility. I inspected the blades but could not find any burned or damages. The time it takes to enter the reboot cycle is not consistant, at times it happens in a few minutes or sometimes a few hours. I got my S5 via the DHGATE link at Bitmain's site together with a friend and he too has the same problem. Currently to get stability, we ran the freq at 300 and 325 respectively. Any ideas? Thanks.

Please try and find the exact model, as its the first point of debugging for your problems.

Please can you try and take a screenshot of the S5's status page when you're getting degraded performance? What firmware version are you on - it should look like a date. How can I tell what firmware version I have now? - Navigate to System -> Overview and look at "File System Version".

I have used my S5s now for about 9 days, I like the lightweight design but I don't understand why top isn't covered. One piece plastic cover over the top and sides would have been very easy to make.
Noise is terrible, If so much fan speed is needed top should have cover also. Before I covered top with ESD plastic and duct tape I could easily feel air flow 1m over the miner. Very hard to built efficienf cooling for many rack mounted miners if air flows almost every directions.
I installed S1 fan pulling to one miner, original fan speed is 3960 and S1 3480, temps 56 and 50 1320GH/s.
One fan miner 3960 rpm, 54 and 49 temps 1312GH/s.
STD air flow seems to be enought, I use DPS-600 server powers.

I hear you. It's called "cutting corners to improve profit margin"...but people still buy them in spite of this inadequacy and so it is. I think the S3 is the best one they ever made for this reason.

Well do keep in mind the miners are disposable. They will be fully obsolete in less than 6-9 months time. So build to junk them. No need for expensive cases.

"Case" could have been made from one sheet of the same plastic which is used now, holes cut for cables at top and U-shaped square "case" covering sides and top. Every cheap plastic thing is stamped "Made in China" so I think it can't be very hard to find producer for this "case".

Whenever you post your next resource, please make it exceptionally clear that overclocking will void a user's warranty.
I am not sure that is necessary as most mining rig owners know that OC'ing voids the warranty. In any case, it is bitmain's responsibility to advise its customers about the terms of the warranty, and to my knowledge, I have never seen any official bitmain literature to that effect, bearing in mind that the so called overclocking frequencies ship as selectable options (on the S5 at least)! Yeah, as we see above / below - someone with many, many S5s who is overclocking and suggesting others do the same didn't know. Overclocking voids the warranty? Then why is it a drop down option in the control panel of your software which ships with the units. I'm not trying to start a fight here. But I find that it's ridiculous to put an option to set a frequency higher than 350 with a simple dropdown menu - in your own software - and there be no warning whatsoever - and that BM would deny a warranty claim.
Yes it does. I can't really answer on behalf of the other questions as its not my rules. I added an overclocking question to the wiki. Is overclocking allowed?
Users may overclock at their own risk but overclocking WILL invalidate the product warranty. This is a more official quote if you will, there is a bigger quote but this is the best one I can find with search as it is. Over Clocking will void your warranty on the unit, please be careful ![Cry](https://bitcointalk.org/Smileys/default/cry.gif) To me this seems:
1.) Shady: Bitmain advertises the product on its own thread as a device with "Overclock Potential". No where is it clearly stated that doing so voids your warranty.
In order to find this "Phantom Warranty Policy" one must first dig through a Wiki, where the information is buried. I didn't even know there was a wiki.
2.) Perhaps not in China; but here in the USA we have Consumer Protection Acts on both a state and Federal Level. From what I understand BM now operates offices/has employees within the borders of the US. These laws do not like hidden fine print, and having a business presence and conducting business here in the states would give the states and the Federal Government personal jurisdiction to enforce these laws.
These laws cover things like Intentional Misrepresentation to Mislead, and because Im now slighly upset my topic has been derailed: Intentional Infliction of Emotional Distress. Both of which are subject to punitive damages as well as Treble Damages.
3.) I'll add it to my post - HOWEVER - Bitmain should be forthcoming about this policy if in fact this is the case.
4.) I had an S3+ go bad - It WAS overclocked. Bitmain was very helpful and responsive and swapped it out for me.
5.) I am in no way badmouthing Bitmain. I love their products. I run 60 S3+ Units (Roughly) and 24 S5 Units. I have only had a single failure. Thats really great in my opinion considering how high defect rates are on name brand consumer electronics. So +1 for BitMain.
What I would like; and I feel the community deserves, is a response from Bitmain from Bitmain's account. They should clarify their position. And if this claim is true, they should add this information to the Warranty Section of their website at the very least.
Lastly; I purchased my units with my Amex Platinum; which extends all warranties on all products for 1 Year past the manufacturers warranty. This is a great feature, however I doubt Ill be running these 15 months from now considering difficulty.
I'd just like to add that we have gotten sorely off topic here:
I put together a diagram as a reference community members could use. I did this on my own time, and have given it freely without asking for any compensation. Dogie... Respectfully: From the start of this thread you have responded with nothing but comments that come off as harboring animosity that myself as well as other miners are getting hash rates which are nearly 15-20% faster than the units were rated at-- and do not deserve. As if we are in the wrong and Bitmain got the short end of the stick by not charging more. How about a "Wow, great concept", not just to me but to all the other members who have contributed to this new technology system. You all know who you are. Ill refrain from going through names simply because I don't want to miss anyone and the list is long.
Dogie, I read your Guide as well; but personally found it the least useful in terms of how to get the most out of your miner; best setup practices; tips and tricks, etc. It was pictures mostly of things I have no need to see on a macro level.
StratoI'm moving the discussion quoted above on Bitmain's warranty policy here since it was getting off-topic as per the OP, but I think it warrants some more discussion. I also had my own comment, which is that Bitmain should make its warranty clear and conspicuous. Some people may be misled by the fact that Bitmain advertises the overclock potential of its miners when overclocking voids the warranty. I don't think something should be advertised as a feature if it also voids the warranty, unless that fact is made clear to the buyer. Just my two cents. Another question on the warranty - any warranty issue will obviously cause some downtime, which is a loss to the buyer. Does Bitmain allocate an equivalent amount of hashing power from its cloud mining service during the downtime?

I just got my S5 hooked up today. I'm currently running 1 S5 on a 1300W EVGA Gold and will be adding a second. I replaced the stock fan with a Delta Electronics AFC1212DE-SP02 (Dell P/N Y4574) 120mmx120mmx38mm Cooling Fan, 148.34 CFM, 51dBA, 3900 RPM, 1.60 AMP, Dell 5-pin 4-wire Connector, which I bought on Amazon for $25 after shipping. So far I'm very impressed and my board temps are at 55/51 while running at room temperature in my office. I hooked the fan up using a molex adapter which is pulling power directly from the PSU.
For the noise level I went from 75 db stock fan to only 59 db with the Delta fan.
Using a kill-a-watt meter it is pulling 587 Watts at the wall while running at the factory 350MHZ speed and hashing at 1155GHs. That equates to a 0.508 W/GH ratio which is right on spec. I also suspect that running the smaller fan is probably saving me a few watts too.
I have 2 SP20 miners running at the same hash rate underclocked and they are getting about a 0.54 W/GH ratio, so for the same watts/hash rate the S5 is winning that battle. 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 feel alot of air escaping the top and I'm forced to place these on a flat surface so air doesn't escape the bottom as well, where for the SP20's I can stack several of them. Not to mention I don't have to alter the SP20's fan or design. It's truely plug and play.

They are a few options you can do, most of them "today" are not worth the hasle but most of the time, they are good and you just point your miners to the better one.
1 - Nicehash.com ( they pay you for your hash in BTC, usually better than mining straight bitcoin ) 2 - LeaseArig ( you rent your rig to people ) 3 - betarigs ( same as above ) 4 - miningrigrental ( same as above ) 5 - multipool.us (profit switching pool ) 6 - and of course mining new coins at release and trading them went they hit the market ( If they do, its a gamble but pays best most of the time )
The easies is Nicehash put a password of (p=0.01225) this is the current payout for mining bitcoins today, so if nicehash pays above, you`ll mine there, if under it will default to you second pool and mine bitcoins at your pool choice.
Hope it help and Happy Mining.

That is very helpful. I did not realize that about Nicehash. Thank you!
