Butterfly labs bitcoin miner drivers
I put a small fan that blows on my units. Quiet and all units bounce from C temp. Also get rid of stock PSU. It generates to much heat around miner. Without the coolink 64 degrees. I have the big fans in the opposite direction, so 1 big fan blowing to the heatsink, the otherend is blowing air out.
The smaller fan is blowing down on the heatsink set the control to max. Everything back in the original case, except the 2 perforated plates are not added on the sides because these cause more noise. I bought just a 60Ghz Butterfly off eBay to learn more about mining bitcoin.
After finally getting it to run the temp was topping out at 90C, and the unit itself was shutting down processing, cooling off and then starting up processing, over and over in just a few minutes of starting to mine. I touched the top of the unit and nearly burnt myself — I exited BFGminer and left the unit running to cool down. Oh the noise it made was similar to small airplane up close. While searching for solutions I stumbled on this article.
I checked the fans and both fans where pushing air out with no air intake, not good. I opened the unit up and flipped the fans on the heat sinks to push air down, and insured one fan on the end was pushing air in and the other was pulling air out. Before I made this change the unit only ran for 6 minutes before I had to shut it down due to concerns of heat.
After the change I have been running this unit for the past 50 minutes yup I started the timer on my phone thinking it would fail at about 6 minutes again and the temp has stayed around C. It still runs load but nothing like before. I have a small oscillation I can hear and will reopen the unit in a few minutes to see if I can fix it.
Thank you for this excellent article. Moving forward with learning about bitcoin mining. Do solve my overheating problems, I just replaced the crappy thermal pad with a bit of Artic Silver 5. Your email address will not be published. A Torx T10 driver to remove the case e.
Remove the four Torx screws from one end of the unit. Slide off the casing. Remove the four Torx screws from the opposite end of the unit. Remove the two Philips screws from the heatsink fan. Turn the heatsink fan upside and screw it back onto the heatsink. Use the 3-pin Y-splitter to connect both fans to the single 3-pin fan connector on the mainboard. Slide the case back on and screw the end-caps back in place using the Torx screws.
Did you try to run it without the case on and see if it had any impact on the temps? This thing is far and away louder than the eight GPUs I used to have running full-bore minting Bitcoins. Something needed to be done. I took it apart to see if any improvements could be made.
Two problems stood out: Rummaging in the closest revealed a pair of Corsair mm fans and a 3-pin power splitter, so I already had all the hardware I needed. Flipping the heatsink fan around, replacing the stock exhaust fan with a quieter model, and adding an intake fan took about 10 minutes. The noise coming out of the unit is easily half of what it was; using a cheap iPhone sound meter gave a reading of 60 dB for comparison, the same meter read 55 dB for a pair of mining GPUs. The blue arrows indicate the direction of airflow for each fan.
Hi, I am following your instruction try to scilence my miner. However I can only remove three of tje four screws. I cannot get the last one off no mater how hard I try… Do you have any suggestions?
Try re-tightening all four, then slightly loosen each one. Keep slightly loosening them as a set e. Try holding down the metal pole that sticks into the fan and to which the screws attach.
Otherwise, the whole metal rod may start spinning which defeats the purpose. Reversing the heatsink fan to point down resulted in a 4 degree increase in the reported temps. Not sure why, but it seems to work better in the opposite direction. Thanks for the info! I found the opposite result on my rig, but good to know that some experimentation may be needed to find the optimal temperature for each unit. Can you share your temperature stats? Silence, same directions as you.
Hovering at around 76 C. The ambient temperature seems to have a strong impact… during winter, I rarely ever saw it break 70 C. I took my miner out of the shell, flipped heat sink fan and operate it like that. I put a small fan that blows on my units. Quiet and all units bounce from C temp. Also get rid of stock PSU.
