Well, I pulled the fan connector off and let it go. Temps quickly raised to 65, 70, 75, 80 and since I had M's monitor program running that even popped up a warning that my temps were over 80c. So I took a quick screen shot and immediately powered down. What's weird is the 5s hashing went away and the average just kept going, which was pumping the temps up. I had an iR gun pointed into the fins and I couldn't get an exact reading, but at one time it came back with 194F, which is 90c. I didn't want to risk anymore so I shut it down right away. In this case that miner should have stopped hashing, all dropped to 0 and made my pool connections dead. But it kept them alive and kept hashing with no fan connected. That little box below the fan#2 and fan#3 is M's monitor program I had running. I set it to alarm me when the temp hit 80c. And it kept popping up on me when it did, so I included it in the screen shot.

Thank you. Message received. I also found another screen shot of an S5 with temps over 90c+ from Rabinvotch. His unit didn't stop hashing or shut down either when it hit 80c. He has a screen shot in his own thread, and I'll grab it from there and put it here also.

Temps should of not reached that high. Machine should of stopped hashing or "freeze" like Dogie said. How could it still be hashing at temps in the 90's when there is an 80c shut off?

Oh, I thought you were "in" with Bitmain and could get another S5 fairly quickly if yours blew up while testing for the team? Fresh controller? Your controller died or something?

Is this software able to reboot an S5 when it reaches a certain temp?

This is exactly what happened with mine. The connection to my pool didn't drop out %100, but was still hashing at like 400Gh/sec. I knew something was wrong when I heard my fan slow down considerably. Soon as I checked the web interface and saw the 92c I kind of freaked and just powered them off. So regardless of what everyone says we shouldn't even be seeing a temp over 80c on our screen if the shutdown/freeze/stop is working properly, correct? I would have grabbed a screen shot but I didn't want to burn anything up. It confuses the hack out of me. Not hashing, but the temps kept rising and I physically felt the heat from the miner before powering off.

Dogie, I know you want to keep dismissing that this could be a bug in the firmware so would you go on a deal with me here? I'll pull my fan connector off while it is hashing to see if the miner stops operating and protects itself when it hits 80c. I'll perform this if you promise me a new S5 if I burn my rig up?

What does this mean? I'm grabbing it from the output of cgminer. I only have two pools setup and the third one is a blank. Is that what it is trying to test, the third one that has nothing in it?

You found a block with one of those or another miner?

I do not want to put my miner through any "testing", since I want to keep it running and not blow it up. But the temps definitely do go higher than 80c, which "should" kick in the fan to spin higher but it doesn't. If I had a test S5 to play with I can probably find a way to duplicate the results I was getting before. In my mind once it stops hashing the temps drop, fan slows down because of that. I wish I could explain it with some proof, but I can't since I have no data to prove the temps went that high.

So when it hits 80c what is it supposed to do? Shut down? Stop hashing? Lock up?

If you get free electric then any speed is worth it.

I was previously on here before, but I'm so use to real time graphics and stats I switched. I did have issues configuring my rigs to connect and what to put in the worker field, but then tried to look up my stats by searching for my btc address and couldn't find it. Is it true Kano pays the users here manually? When I tried to use my API I just got a white page with all the information in black text on one line across the screen. Maybe we can get some real world examples on what to use in the URL field and worker field and how to exactly access our stats and maybe more users would join up?

If I had tons of hashing power of course I would try to set some up on here, but when you only have so much you have to point it at a pool that solves blocks more often I think. This is my opinion though and everyone says it all evens out in the end, but I don't see that.

It doesn't need to be mining. Once the pool drops or connection drops, the fan slows down and the temps keep rising. I can keep my iR temp sensor pointed at a certain spot on one of the fins and it will gradually get hotter and hotter.

I was trying to add antpool.com but I've already been disconnected from that twice. I guess they still are getting attacks. I'm back to Ghash (yes, I know the world hates them), but it seems to be the only pool I can connect successfully with, and with stats. I tried CKPool, but wanted more stats. I couldn't find them.

Also, can I run this on my linux VPS?

EDIT: Downloaded the master and uploading it now to my VPS. Then I can access my miners from any computer on the net. Very nice.
EDIT#2: Maybe not. I'll need to port forward to my miners address but they have to be using different ports. Is there a way to change the default port to another number or is that hard coded somewhere?

My antminer S5's aren't shutting down when they hit 80C or above. Could this be a cgminer issue? The temps start runaway when you already have been mining and get disconnected from the pool/network. Even if the miner isn't hashing the fan will slow down and the temps will start to run away. Soon as I saw 90c I think it was I powered mine off right away. Now, if you turn on the miner from the start with no connection to a pool it will be fine. This only happens while you were hashing then get disconnected. What's really weird is my Dad also has an S5 and the same thing happened to him. He was hashing on the Guild and he heard the beeping, walked over to his miners and the fan was not spinning. Then he felt the heat coming off the top and smelled that metal heat type smell and quickly powered off both miners. If we both weren't home and this happened we'd be in trouble, possibly a fire? I also posted this on the Official S5 page, hopefully there will be some kind of fix. I tried using M's monitor program but that only gives you an alert if the temp goes over a certain amount. It doesn't power it off.

Was told this issue is probably in the bitmaintech driver code and they need to resolve it.

All stock. And I just read other's are having the same problem. Temps over 80c and keep climbing. Not good. If I wasn't home I'd have two toasters.

Remember, they weren't mining or even connected to the pool at this point. The temps just started rising past 80c without shutting down. The firmware seems not to shut the rig down when it is over 80c. That really needs to be fixed.

How do we add a pool if it is not there? I wish it would let us input the URL pool ourselves then be static.

Possible bug in firmware. A critical one.

I had my pool drop out on me, they were having problems and I was disconnected, so the miner wasn't hashing. The fan slowed down to almost like 100-200 RPMs but the temperature kept rising. The fan NEEDS to keep running to keep the ASIC chips cools weather hashing or not it seems. Temps went up to 75-80 so I turned them off right away to let them cool. Bitmain, you need to review the firmware so that when the rig gets disconnected from the pool it doesn't disrupt the fan speed to keeping the chips cool. If I wasn't home and didn't hear the beeping sound I'm wondering how high that temperature could of went to. I actually felt the heat if I put my hand over the miner. It can't just be ambient temps, because these chips cool really quickly...so something else is going on here. If you want to try and test, pull your ethernet cable out and see if your fan stops or slows down and watch your temps closely.

Once I re-established a connection, everything looks good. Any ideas on this? We don't want burnt up miners, right?

I'm trying out antpool and I don't see or get any stats at all on my workers. My rigs are certainly hashing, but the web site doesn't display anything. I should at least see my current hash rate somewhere. Is there a trick or something to get your stats to display?

I'm using

stratum+tcp://stratum.antpool.com:3333
worker.1


Scarey not to see your stats, so I wonder where the return is going to go?

What pool to try and use. I never tried antpool and I don't think I ever tried Kano's pool. Didn't Kano have a pool up a while ago and then shut it down? Is that the same Kano?

This place down again? All miners just stopped hashing on this pool and dropped to secondary already. Every damn pool is getting hit. POOL OPERATORS, put some more protection in there will ya!
