I found a way to change the fan speed to whatever you want. You can edit the html ..

The changes to /var/WWW folder (where you edit the HTML) shouldn't be persistent after reboot.

Network Connectivity is via a standard ethernet cable.



You can change the following file to lower the fan speed below 20.

Code:
vi /etc/mg_custom_mode

FAN:10 VS0:650 VS1:650 VS2:650 VS3:650 VMAX:700 AC0:288 AC1:288 AC2:288 AC3:288 DC_AMP:170


Two comments .. pink is NOT standard Grin .. and the fan hack might void warranties if outside the allowed range .. >> see here <<

I found a way to change the fan speed to whatever you want. You can edit the html to change the fan speed drop down value with chrome or firefox by right clicking on the drop down and select "Inspect Element". The html of the page will appear on the right side of your screen and you can change the attribute and text value of "40" in the dropdown list and change it to whatever value you want. After you edit the html, just click the Save button on the page. I verified in ASIC stats page and I set my fan speed to 20. FYI, my settings page shows 40 still because that is the lowest option in the dropdown list, but it is running at 20.

Here is what the html looks like..




for the option value that is "selected" in this case 40.. right click on the 40 for value and select "edit attribute" then change the text to 20. Right click on the text value >40<, and change that to 20. Click Save and restart your miner. Validate on the home page and in ASIC Settings

could you give details on how to lower the fan to 5 via ssh method. TIA  phil

you can change the following file to lower the fan speed below 20.

Code:
vi /etc/mg_custom_mode

FAN:10 VS0:650 VS1:650 VS2:650 VS3:650 VMAX:700 AC0:288 AC1:288 AC2:288 AC3:288 DC_AMP:170


this is very interesting, i must have a play around tomorrow now that all those expensive rentals are finished paying me ludicrous rates to borrow it!

I assume I could do  5 or 10 or 15 correct?

I got it to go to 15   now to see temps.   have a warm room but heavy duty under clock




here are temps:
will check in 1 hour.

Great review and fan hack is great as well  Smiley.
The settings shown may work only because input air temperature is 12C.
At 32C in my "mining" room, I have to go much higher in fan speed (50) at similar chips voltage, hence lower hashing (1360 Gh).

The keyboard on top of the miner reminds me of the shoe-on head photos.

Disclaimer: I received a SP20 from Spondoolies tech for review. Thanks Guy! This review is being written after 3days of use. The unit has been functioning as per expectations (hash-rate = 1.46GH/s at 800Watt at wall through a 1KW 80Plus gold PSU)

Meet the SP20 Smiley Full-size Keyboard for scale:)


Unboxing. I like the eco-friendly padding material. It does the job well and is bio-degradable






Network Connectivity is via a standard ethernet cable.
Power delivery is through 4X PCIE-6 pin power cables, the ones that power GPU.




Comparison with an Antminer S3.


Detailed Review

The miner when first connected to the LAN uses DHCP to acquire a local IP address. It also sends data back to spondoolies tech so that the miner's IP address can be identified by going to http://myminer.io
HTML web access to miner is via http://IPaddress of your miner
Code:
 Username admin
Password: admin

You can ssh to it as well
Code:
ssh root@
password:root

The fan on this miner is very Loud at all settings from 20 to 80 fan speeds. One can change the fan speed lower by ssh'ing into the miner and editing the config file.
IMO fan speed of 5 or lower has been tolerable for me in a home environment.

The fan pulls cold air through this outlet over the heatsinks covering the Rockerbox ASIC chips.
There are 8chips inside this device.

It will take an average user no longer than 10 minutes after unpacking to get start mining on the SP20.

The fan on this miner is very Loud (Loud is an understatement, esp. when compared to the whisper from the Antminer S3. The fan noise is similar to the noise from a small vacuum cleaner; similar to the noise heard in server rooms when the fans are running at full speed). The fan is loud at all settings from 20 to 80 fan speeds.
One can change the fan speed lower by ssh'ing into the miner and editing the config file.
 
IMO fan speed of 10 or lower has been tolerable for me in a home environment.

Here's a screenshot showing the hashing speed. Note the lower fan speed (10)
