Butterfly labs bitcoin miner setup
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. 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. The Jalapeno ended up occupying the cases originally meant for the single and little single on the right. The other products in the line experienced similar changes. Like the rest of the product line, the Mini-Rig changed considerably from its original specifications. After announcing changes to the product lines due to engineering difficulties, BFL announced that they would honor the pre-orders with the specified speed for the original price.
It is also worth noting that BFL did not meet their original specifications for power consumption on any of their models. After unpacking the Jalapeno, I went ahead and plugged the power cord in and connected the USB cord from the back of the Jalapeno to my Windows 7 desktop. My desktop immediately began to download the drivers for the Jalapeno. With the drivers downloaded and installed I decided to go ahead and give Butterfly Labs mining program, EasyMiner, a try.
To download easy miner just follow this link. It is a pleasant upgrade from my sometimes finicky GPUs that will on occassion go offline. Calculating ROI on Bitcoin mining equipment is a bit tricky. However, considering the investment in potential Bitcoin lends different results. In other words, considering that a BFL Jalapeno had a price tag of roughly The Jalapeno appears to be well crafted and is running at decent speeds.
With that said, at the moment I am not planning on investing much more into Butterfly Labs.
