Question for Cube owners who have had them apart.

Do the heat sinks have thermal paste on them or ?

Thanks,

It has thermal pad underneath the heatsink.

Has anyone removed it and stuck some arctic silver on there?  I presume these have heat sensors that throttle?

  in my experience if it has a thermal pad switching to paste is not that good of an idea.  one reason a pad is used it to match less then perfect chip face to less then perfect heatsink.   if you replace with paste  you are worse off.  unless you buff out the heat sink and the chip to mate closer… problem with that is the chip may not sand up to the smoothing out of it.   
Do this first:

make sure the heatsink is tight and consider a better fan. leave the pad alone.   


  if a no go then try a higher quality thermal pad .

 BTW  what is the thermal pad and is there a better pad out there for this gear?

That my reason for the question. Is there a better way to remove heat? Assuming the cheapest method was used and not the most efficient is it worth "fixing" so they can run at high clock speeds without harming the components.

yes buy an external fan like this


http://www.amazon.com/gp/product/B009OWRMZ6/ref=s9_simh_gw_p60_d0_i1?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=11281RHPP98P0XWTJ15V&pf_rd_t=101&pf_rd_p=1630083502&pf_rd_i=507846  

 dismount the internal fan.  mount this externally and this will blow 2x the air. 

 or leave the internal fan in
place and add the one above.


or stack 4 cubes into a square and mount this against them

just a fast google and you could find one for under 20 bucks.

12/19/13 I am out of cubes. Cubes that shipped 12/18 will receive a pm in the next 8 hours. If you have provided shipping labels, please watch your tracking numbers to see when they have shipped. Any orders not confirmed/and/or shipped yet will be confirmed in the next 24 hours and will ship Thursday or Friday. I am changing the payment address for all new orders of any of my products to 14wUQTiS2ZqfXptbiKTEWjRxxkdKUQfNai . I am taking PREORDERS for cubes at the same pricing as before below for shipping on Friday 12/27/13 and/or Saturday 12/28/13. If I don't ship by these dates for some reason, I will gladly refund your bitcoin. All orders are shipped in the order they are received/paid. I may receive the cubes sooner and will ship earlier if I get them earlier. No orders will ship on Christmas day 12/25/13 and Thursday 12/26/13.

  All cube orders please pay attention to the following by forum member vnhyp0 . 

I have had a few boards get a few boards that are half or full X's and have taken them out completely from the unit so it does not reconnect every 2 minutes. One way that has fixed the X's has been changing the clock to high and back to low. Some boards will have 0's on low and X's on high; I was able to group the boards that would work on high clock setting and the ones that worked on low (i.e. showed all 0's) into separate cubes. I then just ran the boards on low that had X's when set to high, and set all the others to high. Hope this helps some.

To avoid this if you haven't opened yours yet: Take the 4 screws off the front and pull the boards out carefully. Make sure each board has all 4 screws in snug on the heatsink (several of mine were loose), and make sure each card/heatsink is seated completely in the socket (a few of mine were not fully seated after inspection). The sticker on the front of the fan flew off of 3/4 of mine within 10 minutes of running and stuck to a board inside, so I recommend trying to get it off if it is easy to do (else you might have to later after it gets sucked in). Then, Carefully, slide the boards back into the case along the grooves, plug the fan back in, and screw the 4 screws back on, making sure the entire time to watch the LED lights and other fragile stuff around the edges of the card (ethernet, usb, power input, etc.)  THEN plug it in after all that and start mining (Don't forget the fuse!).

I bought 4 and didn't do a through check on them all, and each had some minor issues. The last I've gotten I have checked like this and had zero problems. Hope this helps stops any headaches before they begin. It may seem a bit overkill, but it only takes a small bit of time to save a big headache!

okay thanks to SSB for fast shipping Boo to the USPS for taking 4 days via priority mail.


ALL FOUR CUBES HAD LOSE HEATSINK SCREWS AND ALL FOUR WERE NOT IN THE CORRECT GROOVES.  I took a lot of photos will post a few.

for photos
every cube sent had one or more misaligned boards


 



use  a roll of paper towels and some antistatic bubble wrap to push the boards out



almost there


all resting on some static guard plastic. from that asus gpu in the photo

I removed all 4 heatsink screws  I had many screws loose on the 4 cubes



 chips heatsink and thermal pad

a few more photos


proper boards in the grooves






set down deep in place




make sure this little usb is lined up it tends to get out of place.  sorry for the blurry photo



I use a cheater plug for a psu.

Mine won't start without a 3 pin fan attached internally?  I just figured it was a safety feature.  I tried to put 110CFM delta fans inside but they are 2 pin.

Do you have a link for that PSU plug?  My paperclips just don't look good.

Du u have a link to a cheap PSU I can quickly get from best buy or any other B&M store?
What's this plug you are using? What is it for?

[CloudzEye]

Finally, after all the setup hassle, got my Cube up and running at 38GHs High clock with 98% efficiency.
Surprisingly mine arrived without any loose part or X's chip.
Used different kind of power supplies and finally get two to work.

Corsair CX430M -No
Corsair HX750 - No
Seasonic X-1050 - No
Thermaltake TR2-700 - Yes
Corsair GS800 - Yes

Anyway, does anyone successfully run it with bfgminer or raspberry pi?

Yes, just set bfgminer up as the proxy on your pi and point the cubes to the pi. Worked just fine for me using Minepeon on the Pi and adding this to the box in settings > miner startup settings>

#!/bin/bash
/usr/bin/screen -dmS miner /opt/minepeon/bin/bfgminer --http-port 8337 --net-delay -S all -c /opt/minepeon/etc/miner.conf

This has worked for me but I have only had the chance to try with 3x cubes at one time.

Good info, thanks!

How loud is the Thermaltake?

I am using Raidmax on blades because they have the fan boost button which I leave off and they work perfectly and are virtually silent. However they don't make anything strong enough for cubes with the button available.

I can't really hear anything from the power supply since the fan in the Cube is so loud. But I tried to lean closer to the power supply, it is fairly silent for me.

 my psu did not need the resistor some do some don't.  I just snipped the resistor out.  I can use it in another place.

 plug tricks the psu into turning on.   I do not know what power supply to tell you to use.  I do know now that  none  of my seasonics would work.

I  found out it is picky about the internal fan. hates noctua   has to have a 3 pin fan.   so far this one is best.

  runs quiet .  

I put this on the outside of the 4 I have

end of story dead cool  set the electric on low. quiet and the yellow fans look pretty.

pretty much hit or miss on the 3 pin fans.  do not use a noctua  it buzzs like a bee when you power down.  I sold all four that I ordered.  I am going to order 2 or 3  more on sunday.

Why do u need this plug? Shouldn't the PSU turn on when you plug the cube to it?
