yes , connectors outside is warm

thanks . undestood.


please tell me, How many temperature is hot ? i can't  distinguish hot and warm . just i that touch hand probably warm

In order to touch something and feel that it's warm, generally it needs to be over 95F. If the wires are in contact with the miner or psu, of course they can receive that radiated heat and seem warm. Personally, I don't think you have anything to worry about, but you should take precautions like I stated earlier. If the connectors are warmer than the outside of the miner, then yes may need to worry. Just keep watching the hashing rate on the miner, if it dips too much, it's probably not getting the power it wants.

Your fine,everyone's cables get warm,if they got hot,plastic gets sticky,then worry 

how to undestand temperature ?


yet i can't s3 turn off, it is runing on pool .

Though anyway i think probably itn't warm , it is very little warm .

but s3's temperature is 40

If you have nothing to test watts or temperatures on the PSU, then there's nothing you can proactively do. If you are still in the 3 year warranty time of that psu, I'd hope it does bad before the warranty expires. Either way, it'd be best if you keep the PSU on a grounded metal surface, in case something does happen.

But touch each of the power connectors that is attached to the miner. If any of the connectors are unusually warm in a room that's less than 80F, you may want to worry, or consider having a backup PSU. If only one or two connectors are hot, try swapping them around, and see if the ones that are warm change. It's possible that a loose connection causes heat at the connectors. Also keep the PSU plugged into something properly grounded, that also has over-current fuse protection, in case of a fault.

else , s3's psu is warm also my computer PSU case that i touch hand it was also warm litle hot, but it pSU i use probably 1 year ,

i have this pSU > http://i.ytimg.com/vi/8v5mHcZtUKY/maxresdefault.jpg

i use four connectior .
my cables just is warm.
s3 use 450ghs .
electro effection is "bronze".

just warm is cables.

If the cables are not getting their heat from the miner, then you are wasting electric causing a fire hazard and starving the miner for power.

In that case use all four connections to the miner. Make or invest in good adapters if you need to use them. Most adapters I have laying around are crap and they'll heat up on the electric pull of the miner. If you have a kill-a-watt or similar, check what the psu is pulling at the wall, try to stay under 90% of how much power the PSU can put out. If all else fails set the frequency lower and mine slower.

I have a PSU that's running a s3 at 250Mhz, connected to a UPS, and I stay pretty steady at 410 watts at the wall with fans at 100%.

Most good PSUs have easily a 10 year life, the cheaper ones may die out in 6 months to 2 years, so if you also have an infrared temperature gun or can check the temps of things in the PSU, do so. Capacitors might be the first thing to pop and start smoking if it's going bad. I wouldn't want to see a capacitor over 60C(that's 140F). The large transistors are ok being 130F on my fanless PSU, expect the heatsinks to possibly be that hot as well.

Are you using a cheap psu? Also what do you mean by hot? Is it like melting hot? Or warm?   

Just did not provide enough information for us to help much.

my s3 psu case and cables is little hot, what will do i ? 

Running 2 S3+'s on a single cart, one lower than the other but due to power supply lead length had supplies on the first shelf, miner on second and third and supplies on the top.  Had cheesecloth on each intake.  Yesterday one of the S3+'s was running 8-10° hotter than the other.  Remove cheesecloth from both and the temperature on the hotter dropped.  The cart faces a window fan exhausting heat from the room and the cooler S3+ was more directly in line with the window fan pull.  This morning the hashrate dropped according to the pool so I checked my miner's GUI's and found that yesterday's heating S3+ was only showing chain1.  Took the miner out, cleaned dust, put it back and still only chain1 which in this case is the left side while facing the RJ45 and typically that's chain2 in a 2 board configuration.  Both fans run.  Will continue to troubleshoot but what I found so far is that with the top off and checking voltages, with 12.00 volts set on my power supplies and the supplies having digital readouts, I measure 11.85v on the inside hashing board PCIE (this on the one hashing while the non-hashing board shows 12.00).  So, each hashing board getting fed with two 16 gauge wires, one to each PCIE, .15vdc drops in the wire run (about 30").  Will now reverse the controller board....

It's been very humid, rain, present pressure 29.40"Hg.

----------------------

Flipped the controller board around so the hashboards have swapped ribbons and fired up.  Again the same hashboard is hashing and the same dead is dead although fan running.

-----------------------

Took the outside cover off the bad hashboard and cleaned the ASICs well.  Figured that removing the cheesecloth might have put dust in.  Fired it back up and still no hashing.

------------------------

Shut it down, reversed the controller board again but this time didn't connect the ribbon to the working hashboard.  Have power to all four PCIE.  Fan on the good hashboard running full out by its sound.  Fan on the other running normally but cgminer reports 0 hashing no chains.

Will try a reset to default although it's been running at stock 225M S3+ default.

-----------------------------

Reset to 192.168.1.99 using the 90 second reset switch close.  First attempt after reset, both red and green of that pair were out but the green and yellow RJ45 leds were lit, shut down for more than a minute and retried.  The top red of the red/green pair tho first solid, went to fast flashes for a period then off then fast flashes then off then fast flashes then off then on then green lit and the RJ45 leds lit, I connected to 192.168.1.99 and found only chain1.  So, it's time to remove the hashboard from the miner and look closely for a problem.  Voltages to the ASICs on the bad board ranged from .80 to .78 so they are seeing power.

----------------------------

Tried it again.  Hashing board and controller both out of the miner, ASICs cleaned and outside heatsink replaced without compound.  All the ASIC pins are clear.  Fired up, settled at red/green pair red lit bright and green lit dimly.  GUI connects but no hashing going on.

----------------------------

Up and mining on a single hashing board.  Discovered a mistake I was making.  I want both fans running.  Previously on a problem S3 I had interrupted the blue wire and brought it to 12v from the supply to get full fan speed.  Then I put in a toggle to be able to switch from 12v to dictated voltage at will.  So, to get the front fan running at full speed I ran leads to the blue and ground.  Didn't work.  Running power to the red and black worked.  In this instance without a board going  to the black, yellow and red, power to the blue didn't get it done.

Drat.  The Bitmain Wiki page says:'We also give you a 24 Month Warranty to all our Products.

But then lower down it says 90 days from manufacturer shipping.

When did the S3+ stop shipping?  Are any S3+'s still under warranty?  Come this summer, heat will kill them.  Down south here this one took an 80° day just fine but all the rain recently, a 29.40"Hg humidity reduced cooling sufficiently that 70°'s killed it.  I did have some cheesecloth over the intake fan to reduce dust accumulation which could have been a contributing factor.

This miner ran stock frequency, never overclocked, since day 1 directly here from Bitmain.

You should get 500 if you bump the freq to 250 and set the voltage to 0750.  480 sounds about right for your freq setting.

I do have it overclocked right now but i was thinking that all four would push me to 500 currently getting 480 avg @ 237.5M which from what i read has a potential of 500 with depending on your unit. But i dont understand why i can't plug in the fourth pin. It's just baffling. Thanks for the quick reply i was hoping this thread wasn't dead.

You only need 2 PCIe for running on normal or OC.

Ok I have a 1200 gold psu and when i  connect the fourth pin to the top of my S3+ it wont start up. I want to mess around with the overclock on the ant miner but cant get the up and running with the 4 6 pins. It will run with two in doesn't matter which config.  . Anyone else with this issue?

Are you going to release a new firmware for S3 & S3+ like S4 and S5 yesterday ?

Anything less than 1% is generally acceptable.  My S3+ at 250/0750 error rate varies from 0.004% to about 0.1%.

it was stated awhile ago the discarded section is not a valid number nor should it be a concern.
my s3s usually have under a .0005% HWE. i dont overclock them tho.. a lot of times they start out with a few HWE, then go days without getting any more.
