CRAP!  My shipment just updated and it is now set for delivery on monday instead of tomorrow....

CRAP!  My order hasn't been built yet

Ditto...and as far as I can tell are ANY miners even being shipped the last few days or are they holding them for firmware updates....no one seems to be passing on that their stuff is in processing or tracking numbers work

or the stuff is moving it is very slow?

sigh...had a 190x order could not get $$$ together ..now have 304x order duh..that may have been a mistake

and yeah I've been looking at the bitcointalk order page it has not been updated in a few days

(well this sucks....BFL deja vu)

Has anyone tried the push/pull method by adding fans to the heatsinks on the free side, is there enough room with the cover on? That should increase airflow quite a bit.

If a person gets a Bitpay refund when the spot price is lower than when you paid, do you get more BTC back?

I'm thinking of buying 2x 140mm fans and just put them with cables ties on the outside of the case at the rear (exhaust side), so they can help a little bit with removing the hot air.

The pre-installed fans at the front of the case are intake fans?!  Are you sure?  That would be very poor design if true.  I assumed they were exhaust fans.

But yes, I think it's an excellent idea to install fans on both ends of the case in a push-pull configuration.

Yes, intake. I think it is better that they are intake as there are no other fans to supply fresh air into the case. Adding a second set on the other end to exhaust will probably improve the airflow and the temps:

Thanks for clarifying that!

Well, no wonder these things are overheating and bursting into flames!  Lol.  How could someone design this simple case and NOT include exhaust fans.  With all of those heatsink fans blowing air around and causing turbulence, I can't imagine the case is adequately exchanging air.

I have a few ideas I'm planning to do.  Yes there is a lot of room even in the Jupiters for adjustments but I think the bigger issue with them is that the front row needs to push hot air out the sides (and above if you dont care on stacking them)

when I get something more complete (research sizes of fans, etc) I will post something


one thing most don't know is that the lid does have fins to try to push air to the sides from the front heatsinks but I think they should go all the way to the sides and have their own vents on the side

adding a few more strategic fans inside will aid the flow a lot

I think the consensus is you take the cover off you find the 1x or more boards that seem to be hot...you then take fan an point it directly at hot unit.....and another fan a bit away from the miner to move air away from the box entirely....and/or find a "cold' basement as well (Minnesota)

Does the above seem to be the consensus on what to do 'so far' till the firmware gets fixed or other issues are dealt with?

yes

this was my quick fixes the day I got them which led my miners to go from ~420 Gh to ~520 Gh which more than paid for the run to Kmart for fans

so now I have lids off to measure modifications and can plan to cool it way better before I put them back on

hmm...if you have a really bad board/chip arrangement is this something that should be considered?

or would you void warranty? (i'd guess yes)

curious need some guy with 'modding' experience to see if something equiv  or better then the arctic i30 heatsink is worth doing?

or, you can just buy a HashFast.

well im waiting on my knc first.

also does anyone have the link to the heatsink setup they are currently using. I could not find it under search.

Well I don't need another girlfriend..ie ...I'm still paying thru the nose for the ex-wife BFL (the skank took me for everything) ..the new girlfriend KNC seems spunky enough but she is kinda a flake on being on time...but then again I've heard she gives great GH.....as to Hashfast...well.....alas.....no $$$ no desire.....no hope on that...I'm tap'd out

Well those are standard heatsinks made to fit AMD and Intel CPUs.  I don't see why you couldn't slap 4 Corsair H80s in there to replace the existing heatsinks.

ok there are "some" folks on here with only 1 really bad board/chip...who prob don't want to RMA yet.......I mean a few of them I think have "really bad" hash on that board like 176gh or some such...they'd be the "target audience" to try this imho...if it was me in that situation i'd probably be game....but then again according to bitcoinrama this stuff is all a "firmware" issue so maybe not worth the effort....a toss up imho

it's really too bad you guys are having to go thru all this trial and error to make up for what KNC should've taken care of.

in HF's case, they hired the water cooling company itself to do heat simulations using all the Babyjet parts except for the actual chip itself.  they used a heating element to put out 250 W of nominal heat production to make sure the cooler could handle that first.  then they took the wattage up to 350 W of heat to make sure the cooler could handle that amount at what is meant to be an overclocked situation.  no problems according to the results from the water cooling company.  they may have even taken it higher but don't quote me on that.  i won't bother to tell you what hashing rate that took the chip up to b/c HF doesn't want to overpromise but it would knock your socks off.

Oooo yea. Giggidy

[Searing]

on a side note I had a "thought" probably a lame thought...but with the folks taking the cover off...I was wondering about the 'standoff' method used to attach the boards and as such heatsinks etc how they are attached to the bottom of the miner plate:?

ie was thinking you could get an extender if they are screw in standoffs and just raise the whole board and heatsink unit up like 2" or some such with such a standoff plug

thus increasing airflow underneath....shoot a usb fan on the side blow the hot air away underneath

or am I just being silly (likely?)

(Damnit Sam I'm a KNC miner...not a aeronautical physics major on airflow!!!) using best Dr. McCoy Star Trek voice.
