I received two C1 and two syscooling kits. One kit has one fan not working. How can I get a replacement?

is it possible to power an s5 with a 550W gold psu? Seasonic G-550 80+ Gold Modular

Only if underclocked. Using HP server supplies my S5's running stock speed pull 605-610 watts from the wall as reported by the UPS's on some of them.

One NEVER ever should continuously run any PSU at or close to it's max output. It simply will not last or be stable. For any constant load eg miners, general rule of thumb is to load a PSU - and the line feeding it - to 80% or less of the maximum rating. So for an s5 I'd go with at least a 750w supply to keep everything happy.

Agreed 80% is optimum depending on efficiency rating on the PSU. 85% is doable too but overloading a PSU in any case is not good and really just gambling with equipment lifetime.

Go Big or Go Home.....

That's a pretty bad design flaw if you ask me. This should be fixed ASAP.

What is the best way to overheat the miner to check if it will shut down at 80C?

Blocking or unplugging the fan in my mind, could be voiding a warranty. My test was to simply disconnect my internet - which is a real life occurrence (failed internet service). It might take a few minutes for the current information to finish its hashing and start beeping, but it will.

Why would no internet connection cause it to overheat?

Oops... I made an assumption, that the way my S5's and Opentoe's are working, that will do it. When there is no internet, there is no new information coming in to the miner to hash. What at least the 2 of us have seen, is when it's not hashing, it heats up. I would try that first, so that if you have any hardware failure from overheating, no internet access is a regular problem that should be planned for (the other options mentioned, are not normal operating conditions expected for the miners - just my opinion).

Another thing... I paid almost 50% as import fee (in Italy)... is that normal!?!

No! Your government is a criminal enterprise. I though I had it bad at 15%!

Ouch
A lot cheaper in the USA even with exchange factored in!

Wow, that's a crazy markup. Where do you live?

Canada no longer exists. Failed experiment.

Yeah everyone had to move south to Yankeestan

Put something infront of the front fan?

disconnecting the fan, is probably easier

Stick it in a small closet with no ventilation. It will slowly overheat itself.

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?

You can configure it to shut off at 80 C but yeah it would be nice to have a control from the GUI.

I wish some others would test this. I had this same type of thing happen about 6 weeks ago. The firmware safety net of 80C shutdown did NOT work (yes, mine is checked). When I saw it, one blade was up to 106C. I mentioned this before, here, but with the Chinese New Year timing, I'm guessing it didn't fall on any ears at Bitmain.

If true a major fire hazard. BITMAIN can you confirm that the 800 C shut off works. I will be operating my miners remotely in the coming weeks and need to make sure that safeguards work so my house does not burn down.

My S5 order shows paid, unshipped, valid, order date 3/18 but then again so does my second C1 order which is happily hashing away in my backroom.

If you crank the clock down it might work, at least for a while.
