I know it is, and so is the suggested alternative .... but the Nidec TA 500DC is a bigger form factor thus deeper fins

What would be the reason to try these? Being 38mm form-factor, the noise they emit has to exceed the stock fan noise.

Try these out ...

http://www.ebay.co.uk/itm/Lot-of-4-Compaq-Nidec-Beta-V-TA500DC-A34538-90-Proliant-Fan-with-Dual-Housings-/251820064274?pt=LH_DefaultDomain_0&hash=item3aa1a53e12

Strictly speaking, these are not 120mm fans and the holes do not match up with the holes on the S5 mount, but they'll sit nicely inside the brace of the fan on an S5 (even S1 and S3), couple that with a slight mod (using this resistor: http://www.maplin.co.uk/p/wirewound-3-watt-33-ohm-resistor-w3r3 on the +ve line) plus double sided tape to hold them in position and you'll get a humming rig with more than enough CFM. If you put them in a pull configuration, the pressure will also help hold them in place.
PS. All the mod does is reduce the voltage to ~7 volts (and thus cut its noise dramatically), so if you have a source with that voltage, use that!

You'll need to strip all the housing off and remain with just the fan.

With free electric, it definitely is more profitable to mine with ASICs than GPU's. If I were you, and seeing you are already with nicehash, I'd get a couple more S5's ..... then you'll be making some serious returns in comparison with your GPU rigs ..... my 2 cents.

If you have the Advanced Settings page, then no need to SSH into the rig, just change frequency then click Save & Apply..
If you do not have the page, then YES, you'll need to SSH into the rig and edit the file manually. Google for Putty, it is one of the common software(s) for SSH'ing ...

Simplest answer is do not flash the 12192014 firmware because along with a raft of S3 firmware releases during that period, that version was scrapped by bitmain (after testing in general release) as being buggy. Proof of the pudding .... check the bitmain website, its no longer officially available / supported.

That is your usual waffle! There is NO official literature on overclocking voiding the warranty, and your quotes, wiki additions and public forum quotes by a bitmain employee can not be used as binding statements to bitmain. Like I said, waffle as usual!

Add to that, Strato (or anyone) is not obliged in any way to add a warning to their threads regarding any statement as to OC'ing voiding their warranty, if only because even bitmain themselves do not mention that anywhere authoritatively. You, dogie, are a simple dogs-body for bitmain, toothless dog if you want, as your assertions are not worth the digital ink that they are written in (let alone have the force to void a bitmain warranty)!

PS: And stop being off-topic here, if you are so concerned about the warranty warning, go and open a thread in the scam accusation subforum or press your favourite link to report to the moderator.

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)!

I am not interested in arguig with or shadowing you, but I shall always point out the misleading information you give out under the pretext of being a bitmain representative. And the ball is in your court here, if you do not want to be challenged, stop giving false advice to bitmain customers (of whom I am). And if you do not know the answer, let others who know answer!

Your self-annointed bitmain representative badge neither confers nor imparts any knowledge unto you to shadow any and every comment on a bitmain instigated thread to the extent of you pretending to be an authority on all things bitmain. That much I know from your numerous waffle responses and the patently wrong advice that you keep giving.

EDIT: If bitmain have scrapped a firmware release, why do you keep telling people to install that release? Will you recompense them if their rigs (which may be out of warranty) malfunction? Or will it be a case of you can not help since warranty period has expired? Do you ever give thought to that you twat?

If it is no longer hosted by bitmain, then anyone in their right mind should never install it as it is junk firmware and will surely invalidate any warranty they may have. It is well documented, and been brought to your attention several times, that the firmware you refer people to causes all sorts of problems but you refuse to take any notice of it.

The most recent person you tried to ram your firmware up clearly has a pre-S3+ rig, i.e Aug firmware, and those particular units have been known to have a decayed performance with the latter firmware releases, but you still jumped at the opportunity to refer them to your special upgrade .... how daft is that?

If you think I am making any un-reasonable accusations, feel free to open a scam accusation thread against me. And your private firmware updates aree the off-topic ones in as far as this thread is concerned! All firmware upgrades SHOULD be downloaded from the bitmain site, not from your stash of compromised firmwares. How bitmain let you potentialy tarnish their image beggars the question, are you their hatchet man? Fortunately, this is not a bitmain forum.

That is bitmain's flaw to have you as a representative if they actually do. Saying that, I've never seen bitmain refer to you as their representative anywhere.

In any case, you should know that it is adequate to simply update cgminer in the Aug firmware as the reset button (your favourite excuse) works well. Just the stratum bug that was fixed in cgminer 4.6.1 needs to be corrected in the Aug firmware, but you did not even ask the OP to check for cgminer version before suggesting your firmware update (for all we know, his unit may have an updated cgminer from the previous owner!).

EDIT: And why do you insist on posting links to your firmware updates rather than refer people to the bitmain site? Does that link contain your own edited firmware where you've introduced suttle bugs to steal hash-rate or some other sinister stuff under the cover of a bitmain representative?

Nothing un-usual about the 58, 48 temp readings (mine has 44, 50 at night-time and up to 52, 59 day-time with just an S3 fan), but worrying in your instance are the restarts .... you need to get in touch with some-one directly at bitmain.

Turns out he had the former .... simply setting DHCP on the active connection.
Saying that, what does a DNS clash look like?

Ignore him! If it ain't broke, don't fix it!
The only thing you'd need to update with the Aug firmware is cgminer, not the firmware else you run the risk of bricking your rig, even worse, installing dodgy firmware (of which there are loads for the S3 variants)!

Beeping is more commonly associated with network connection failure, but you seem to have covered that. (though I'd make sure DHCP is enabled on the active connection nevertheless)
Try manually starting cgminer via the System -> Startup tab. Click on Stop first then click on Start.

Go to status - overview for the firmware date ...

Can you also be more explicit about the "not working". Is it not hashing at all or is it not hashing well?

Make sure network is set to DHCP .... also what firmware are you running (you can get this from the intial web UI page when you log in)

Was not disputing any of your claims, just dogie's waffle responses.
I know the S5 is easily a 1300Gh/s + miner (mine is at 1350 albeit at a higher freq), but now you got me thinking of the S3 variants too .... aka the vertical position.

Nice concepts applied there, aka pointing the rigs up, though I suppose it limits the number of rigs in a space as you can not then stack another set atop them.

Looking forward to your forthcoming guide ..... had a glimpse of the initial thread before the party pooper reared its ugly head!

Strato - nice concepts applied here .... still out on the extra cost of that huge fan though ...



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?


Thats waffle.


Absolute nonsense! You mean the same material occupies less area when curved. Curving does NOT increase surface area (let alone significantly).


So what's this all about then? "They're designed EXACTLY to trap the flow and prevent it from escaping."

This ...


Hedging your position in mining is gambling too. I'll go further and say bitcoin mining is gambling to a large extent.

I did not want to digress but you've forced my hand .....

It's not just the semantics of whether mining is gambling that you definitely got wrong, or whether hedging your position in mining makes it less so (not negating the fact it is gambling though), it is that you can make such a contradiciting statement, pretend to be ignorant of your error and then proceed to advise on something else! Staggering!
