Really? This issue was reported maybe 2 months ago by me. I don't think there will be an update.

EDIT:
Here you go, this is when I first mentioned this problem. This was back in March!!!

Shocked we haven't heard of burnt up miners because of this. I was the first one to report/post about this issue many pages back and it still being discussed. Since I put all my miners on the "always on" molex connections I don't need to worry about any overheating again. I also removed stock fans and use two Noctura Industrial fans which do keep temps in check, even in this 95 degree temps in NJ. Worth the extra money. Those fans have a 6 year warranty and have been superb from day one. They will outlast the miners and then I'll use them in a couple computer builds. All PWM too.

i ended up just pulling the blue wire on the fan for now.. i can always put it back in when its fixed.

That and the fact that KNC are a bunch of huge liars...

nice I hope it's fixed, when ever I leave home, i turn off all my S5 .


for the over heat reason .

Bitmain is already working on this issue, so wait for new S5 firmware.

Next difficulty retarget occurs at block 360863.0 (eta 2.8 days): 46504486469.3 / -2.3% [est.]



going down I did read the blog about KNC and there 16 mm chip it's not suppose to increase hash, if I read it right but save more on Power then anything and be one of the most efficient farms around.

its still working.. i think i got it turned off in time before it damaged itself.
i really dont want to pay to ship it to them, wait weeks, and get mine back because they cant find anything wrong with it.

Agreed, i'm still waiting on my replacement.

email bitmain START TALKING TO THEM NOW

i can confirm the temp problems without internet.
just today my internet went down for about 30 minutes..

they started beeping as usual when it detects no internet and all the fans turned off. i pretty much ignored it and went on doing what i was doing.
after a few minutes i noticed the s5 beep turned into a solid tone.. ive never heard that before.

i went to check it and when i touched the heat sink and it was so hot i couldn't put my finger on it. the fans were not spinning very fast and really hot air was coming out the back. i instantly shut it down.

the internet is back on again, it seems to be working ok.. today was the final day of my 90 day warranty.. i hope i dont have any problems because of this.

this is a problem and a potential fire hazard.. had i not been home who knows what would have happened.

i went and put the fan on a molex adapter.. its not ideal since its now at full speed.. but if the internet shuts off again the fan wont stop.

you dont have them in quiet mode do you?

try running them off molex so they hit full speed..

the problem with that fan is i think a lot of air will be sent to the outside of the boards.. not down the center like you want.

For those interesting in my custom S5 enclosure, I started a thread here with pictures:

well 2 silverstone fhp-141's in a push/pull config isnt enough. damn thing is still hot. not as loud though. not enough airflow.   have to underclock to 325 just to get around 60c

Nope

This is a huge high!  Wondering if it the new KNC or something else.

looks like a lot of network hash is coming online.. seems difficulty is about to go to the moon

I've built a couple laser cut acrylic enclosure for my S5, some that use the frame as a base, some that don't.  I was planning on posting some pictures in a week or so when I'd done more testing with ducting... I'm also doing full heat analysis with a thermal camera, not relying on the temps reported by the board, that are next to useless.  So far my best design screws in on the bottom and sides (fully enclosing them) and then drops in over the the top, basically resting on top of the PCB, with a cutout section for the Beaglebone.  The Push fan configuration is actually less efficient in this situation - so I switched to pull which works great.  Not much gain for push/pull, so didn't bother.  Right now I'm using 5.6mm acrylic (I can easily get it at Lowes, and they'll cut it to my laser cutters max size for me), but I think 2mm will work as well and be cheaper.  Once I get everything nailed down, I'll probably just figure out my yield and go to TapPlastics or one of the larger places that has a greater selection.

On the ducting side I originally tried 4" aluminum flex duct, but there is too much resistance so I've order parts to test with 6" duct (5" is too hard to source generally speaking).  For the 4" I found a great flange that I liked, but on 6" it's more difficult, so I'm opting for a PVC toilet connector, which I will glue to the acrylic - and I think this will also be less work at the same time.

All in all the enclosure path is the way to go - I'm going to redo all of my S5's to use the cases, plus I think the S5 looks quite a bit better when in acrylic.

Anyone who is impatient and wants to see what it looks like can PM me their email and I'll shoot over some images - then they can also confirm that I actually did it. 

Yeah, i think i can pull out the vernier caliper tomorrow and begin designing. Maybe even get a prototype by month's end and see if there's still interest in this type of product here. heh

Syscooling has not logged in since: Last Active:    March 21, 2015, 09:35:43 AM.  So I think we are safe to say we are done with them.

On the 3D cases they are really neat, I think price can go down some as time goes on.  Right now I think most printers are a little time intensive to do out of the PLA stuff.   There are some amazing resin printers but they are pretty pricy.  But I think 3D printing offers a lot of possibilities in the future.
