...

linoleum almost caught fire... Embarrassed

This happened two months ago

Noctua
IndustrialPPC NF-F12 and Super Flower
Leadex Gold SF-1300F14MG

Abbot miracle. after a few weeks of testing to wake S5 ,!right now! awakened.(not first time happened) repeatedly reboot worked.
is not the first time that this series S5 collapse and then again from the fluke is started again. but as long as the internet again collapses or pool.. soo i recomended try repetat reboot or swich power on off..

But the problems are only from the new series S5 as shown in figure. there's probably something more problems but the longer I do not understand.
older series are ok
I use second-hand. so I have no problem with warranty..

just another . I tried to reset it, attach another fan and nothing helps.

I recommend not to buy the whole series S5..

Can you provide a screenshot?

How long have you had it, what are mining conditions, psu, etc?

Bitmain... ಠ_ಠ

Come on guys... At least pretend to care at little bit better.

Edit: I mean, I suppose one is getting a "deal" with Bitmain erroneously valuing coin so highly, but where is the consistency ? Idonteven...

Trust me they are not going to bring it down.

In all fairness, they might drop the price. However, the trend seems to be, quick to raise the price, but slow to lower it.

That rate has been that since the price re-increase ... and honestly, it is them that lose out if they value BTC more than it is (i.e if you are in the market for some, just convert $ to BTC and you are in the money!). Still, BTC value cooling SHOULD have meant a price drop ....

You don't pull up an open collector line with a transistor, you pull it up with a resistor - which has NO polarity.

Try reading the specification sometime, instead of raising strawman arguments with nothing to do with the spec then ASSuming that I have no knowlage of electronics.

your the idiot who said open collector not me. and yes transistors also can be used to change the pull up state state. were did you get your knowledge from a cracker jack box.

If that transistor shorted out the voltage would be equal to the voltage across R1 depending if the 555 timer IC fries or not.

Say no more very simple basic circuit but proves my point case closed end of conversation.

If that transistor shorted out collector-to-emitter, the voltage on the output would be essencially zero.
Also, ONE CIRCUIT does not prove anything - both a PNP and a NPN transistor can be used to pull an open-collector type output to ground, you just have to set up the INPUT to the transistor correctly to do so.

I'm not "the idiot who said open collector", that's from the SPECIFICATION that you obviously still haven't bothered to read.

BTW, where is the 555 timer in the circuit you posted? It seems to have gone missing....

Go back to school I think you missed something.

Yawn boring you nimrod troll.

Will Bitmain fix an issue with fans slowing down when S5 loses an Internet access?

I really do think it is hit and miss on what one's do it. It is not all, but obviously enough to cause a lot of talk.

Instead of waiting for fix I would get molex to fan connector and just not worry about it, if you have an effected unit.

Why the f*ck prices are 414 per ant ? The last time i purchase they were 340$ ?

Let's see how long it takes Bitmain to adjust the price again now that BTC is plunging towards $275/USD...

They wont lower it they are price hogs like I said they are milking the cow.

Easier to just remove the PWM line on the stock fan (I prefer to pull the connector out of the plug then electrical tape it, some folks might prefer to just cut it as that's easier), then it runs at 100% all the time for best cooling.

Not all the time some fans will stop spinning if you remove that PWM wire. and others will spin 100% RPM it depends on the fans controller chip built into the fan. so like I said it depends on what fan.

Any fan that does not run 100% with the PWM line open is BROKEN (either by design or by failure), and does not meet the SPECIFICATION for PWM fans (the spec specifically calls for the fan to have an internal pull-up on that line and the DRIVER to the line to be open-collector).

But yes, I did test it to be sure, having seen way too many items fail to meet specs over the years....

Okay pull up huh , If its a PNP or NPN transistor what is the polarity of the voltage on the Collector when Each type is pulled up think about it.

If the collector was open On each type what would the polarity be.

Learn how the current flows through a bipolar transistor then you will know what I mean.

I am willing to bet they will let it sit at the $414 for at least a week to see if the price rebounds at all.

I had both fans wired directly to the PSU "both S5 original fans" then I remove the internet connection and I was still able to view my miner status page. The temp shot up well above 80c

the bold part there says you are lying...

anyway, your posts are becoming very annoying..

Annoying or not.. I had the same experience he described.

I lost my internet connection when I was out one day. Came home, heard the miners beeping. I physically looked at the miners and the heat coming off of them was tremendous. I logged in and I was able to see a temp of 102 or 106 (I can't recall right now). I freaked out, killed the power and stuck a box fan on them to cool off. So I didn't get a screenshot that time.

I don't know what the software should or should not allow (allowing access or not). I do know I got this screenshot when a pool failed (and the software did not appropriately rollover). The software also didn't shutdown. I know the fan was barely spinning (no matter what the screenshot showed). So I know there are multiple inconsistencies with what the software should do but doesn't. The screenshot temp was in harmony with my IF thermometer reading.

on the official firmware when you lose connection to a pool, cgminer doesnt run the bitmain sensors api and the ui freezes on whatever readings it was on the last time it was ran. it just loops trying to connect to pool.

but in your case the fan did slow down, as well as mine.
but dog1965 is saying his fans are on the psu via molex adapter running at 100% and his s5 was still running above 80c..

It is very troublesome when S5 is used on stock settings for fan. I connect fans directly to molex on psu they are 100% RPM all the time. Tried to kill the internet temps were fine, checked with laser thermometer on boards and heatsinks as well. So anyone who wants to solve issues with burning boards just connect fan on molex and you are good to go.
