Is that your bed next to an SP20 & a S5? Do you sleep with industrial ear muffs strapped to your head? ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) That is dedication. Definitely could keep a eye on it that way though. I personally keep them out of bedrooms ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) You stop being able to hear it after a while, its surprising what level of noise can become the baseline. Its also a lot easier because miner noise is perfectly level. improving your mining power by up to 15% by simply running an additional script and light weight software package
That's a pretty bold claim right there. So a stock S5 will get 1328Gh by a script? Overclocked yes. Im running poolside averages of 1280-1320ish on the units. Whenever you post your next resource, please make it exceptionally clear that overclocking will void a user's warranty. As far as I can tell - Overclocking DOES NOT void the warranty. There is no statement on the website - unless I am blind (possible) - and all the manual states regarding the OC/Frequency is: 4.2 Frequency Modification You are able to modify the frequency value through ‘Miner Configuration->Advanced Settings‘. The default frequency for the AntMiner S5 is 350M. No where does it state that by going above default voids the warranty. I would think from a legal standpoint that denying a client RMA because he/she OC'd the unit has no legal justification - and certainly can't be imposed retroactively. Perhaps Bitmain should add that to it's site or manuals - for new orders of course. Strato

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)

Curving the blades essentially allows you to pack the blades closer together, so it will increase surface area at the expense of increased resistance to flow. It's essentially the same as using shorter fins, but packing them closer together so you have more of them. It makes machining the heatsink easier for the same surface area though, so there are good reasons to do it.
Stratobiz, have you tried just removing the box fan? They definitely move a lot of air, but the linear velocity of the box fan is going to be quite a bit lower than the big Deltas. It'd be interesting to see how much of a benefit there really is.

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.

I think this is for the most part spot on, however I do not believe that airflow resistance is increased with the air flow running parallel with the curve of the blade/fin. I could be wrong, but I believe that resistance is only increased when the airflow moves over the blade like the wing of an airplane. I haven't tried a 2nd Fan. May give it a shot. Strato

along his idea use this idea: use the box fan as a pull on top of the s-5's Philip are you suggesting using 2 Fans in a push pull config? My only thought is the config I came up with funnels all exhaust directly up. Its pretty warm air- and those box fans are PVS plastic. I think over time the blades of the box fan would warp due to the warm air heating the fan blades and the friction caused by the air the blades are pulling upwards. You could end up with a back draft effect where warped blades result in choppy airflow and cooling may be impacted. Just my thoughts. Strato

![Huh](https://bitcointalk.org/Smileys/default/huh.gif) I asked how you were proposing to make huge gains, you replied it was overclocking [which by the way, is not new 'technology' and you're far from the first to overclock an S5]. I asked you to then make sure that you make it clear to people that this will also invalidate their warranty - which you seemd to not be aware of. What is the problem with that?

Strato - nice concepts applied here .... still out on the extra cost of that huge fan though ... They're designed EXACTLY to trap the flow and prevent it from escaping.
Thats nonsense. With the fan that ships with the S5, there's no chane of trapping anything between the blades. In any case, why trap the heat in the first place? You want that air to continue down the entire length of the blades before being allowed to exit, else you end up with an even larger temperature gradient down the blades.
Thats waffle. The curved design also adds significant surface area [heat transfer] for the same amount of material and volume.
Absolute nonsense! You mean the same material occupies less area when curved. Curving does NOT increase surface area (let alone significantly). As a last point, passive convection effects are almost negligible in regards to heat removal when you have active convection operating.
So what's this all about then? " They're designed EXACTLY to trap the flow and prevent it from escaping." Yea. he is a waffle alright lol lol

improving your mining power by up to 15% by simply running an additional script and light weight software package
That's a pretty bold claim right there. So a stock S5 will get 1328Gh by a script? Overclocked yes. Im running poolside averages of 1280-1320ish on the units. ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) I don't think those two statements can co-exist.

Our system is nothing "new" per se. Its just not: 1.) Well Documented Elsewhere, and 2.) Not widely used. Most miners arent even aware of these options. We just got the S5 units up and only ran a small test. Our 60 S3+ units are however using the system. Nice gains. I see no reason why the results wouldn't be similar, but its is why we have not yet posted as we want to run tests before publishing information that might not be fully tested. Strato

Strato Airflow resistance is increased because the distance between fins is reduced. When you have a fluid flowing in a confined channel, you have more resistance along the wall than in the center of the channel. If you have a heatsink profile that's 10" wide and has 11 0.1" fins with 0.9" between each one, it will have less resistance to flow compared to a heatsink with 21 0.05" fins space 0.45" apart, even though the total area for the air to pass through is the same. It's the same principle that causes you to have more head pressure loss running 1 gal/min through four 1/2" pipes than through one 1" pipe, even though the internal area is the same.

On topic: Interesting idea but really costs would be prohibitive to make this viable for home users. Everything is a loss at this point.

Strato Home depot was out of box fans when i went there to day i had t order one due on 11th to my house . once i read this i knew i had do it . ty can't wait for the software end of it now. if you have a BtC address i can send something let me know it won't be much but some thing for a few beers if you drink them . Sorry about that pst I sent , I was wondering if you were working with that guy. well any way I'm glad some thing like this is here. My next buy is a https://ehash.com/product/avalon4-module-1t/ I discovered to day Webb hunting. wait i got your BTC you sold me two coupons i can't get them to fix my other account, i sent two pst so far, I' m about the spam them for a fix, a day or so after the forums crashed, i had my other account for two days then it crashed and came back with wrong pass word, Ive been sending me emails they don't come .

Curving the blades essentially allows you to pack the blades closer together, so it will increase surface area at the expense of increased resistance to flow. It's essentially the same as using shorter fins, but packing them closer together so you have more of them. It makes machining the heatsink easier for the same surface area though, so there are good reasons to do it.
Stratobiz, have you tried just removing the box fan? They definitely move a lot of air, but the linear velocity of the box fan is going to be quite a bit lower than the big Deltas. It'd be interesting to see how much of a benefit there really is.

Yea sorry my response to your PM may have seemed odd, but I had no clue what you were talking about and thought you perhaps PM'd the wrong person. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) Good luck! Also This is a MUST: Pro-Tie Brand Zip Ties. Yes they are more expensive. But they dont snap, break, or become brittle over time. 100% Worth It. Amazon Sells every length. The long ones (30" and Up) are like $1 each but you can literally ZipTie a 30 Lb Large Object to the Ceiling and it stays put. Heres their product line: http://www.amazon.com/s/ref=bl_sr_hi?ie=UTF8&field-brandtextbin=Pro+Tie&node=228013Strato
