Yes the ramsyncs I purchased to put on the temp chip took the temp down from 70-80 c to 55-60c (its in an enclosed cabinet with fans pulling air out of the top.) Unfortunately that was short lived as the Western Power were doing something nearby and we had 3 power surges/brownouts within an hour and it has killed one of my hashing boards.

There are lots of ways to skin a fish but this is the way I chose as the pump I have has a de-ariatioon cycle built into it. Most people with PC watercooling will generally try to bleed the loop by running the pump for a period of time and then shutting it down and rocking the case. Stopping the pump causes the smaller bubbles to clump together and form a larger bubble that is easier to push through the system.



No but that would solve the problem, the two boards that are closest to the centre of the fan gets the most airflow hence the temps are less of a problem, the outer ones don't get enough airflow to keep the temp sensor cool enough.


Thats what I think it is because I'm pretty sure there is no air left in the system but will keep an eye on things for the next couple of days, also without the fans running the temp skyrockets on both boards to 80c and then shuts down.

I will report back in a couple of days after adding the ramsinks to the temp sensors.

It also seems that the ASICs don't have an internal temp probe like CPUs and GPUs there is a LM57A sensor on the reverse of the board to monitor tempratures, the fan keeps this chip cool so honest throttle back your ASICs.

I have recently purchased one of these kits and put in a single S5, left it overnight on a de-ariation cycle, (pump timed to run for 30s on and 30s off for 8 hours) along with tilting and tipping the chassis to ensure all air has been removed.

I booted the miner up this morning and blade 1 was reporting 80c and blade 2 at 67c, the first blade is getting the least amount of airflow due to the position in the case so I am running my S5 as a single blade at the moment and have ordered some ramsinks to stick on the LM57A chip as per goxed advise.

At those temps my water temp is only 30c and the water block is cool to touch but the miner still throttles right back and sits down if I leave board 1 connected, I hope the ramsink will decrease the temperature readout and mean that I can run both blades without shutting down.







The above pictures show the chip that needs cooling down, the rest of the components don't really need too much cooling (apart from the ground pads/heatsink pads) on the backs of the ASICs but moderate airflow will be fine across those pads.



EDIT: This is my stats page with only one blade powered and the water at 30c

I think I know what you are trying to achieve, I'm not on a windows machine at the moment so cannot post any screenshots but I will try my best to talk you through it and post screenshots tomorrow if I can.


Option 1 - Single Miner

1) Fill out the host page as you normally would to connect to your RPi
2) In the left hand navigation pane select "SSH >Tunnels
3) In source port fill out 8080
4) Destination Port enter antIP:80 example 192.168.1.99:80
5) Click the add button
6) Go back to your first page and connect to your RPi
7) Log in to your SSH session and ensure you can see the # or $ shell

On your web browser navigate to http://localhost:8080

This will direct that web request through the SSH tunnel to your Antminer.

Option 2 - Multiple Miners Chrome and Foxy Proxy

1) Navigate to "SSH > Tunnels" in Putty
2) Select the Dynamic radio button
3) Enter 8080 in the source port
4) Connect this session to your RPi as normal
5) Ensure you have the # or $ prompt.

6) Configure Foxy Proxy to use localhost:8080 as the proxy server and to direct all traffic towards the proxy.
7) Navigate to your miners IP as you normally would



NOTE: Please be careful about using this method on a corporate network as this can be used to circumvent certain web filters which will more than likely be against your IT Policy.



EDIT: Didn't read post #3, ignore the above as this will give you remote access to your miners via the RPi as an SSH/Proxy server it will not tunnel the connections towards slush pool through an ssh connection.

As nothing useful is now being added to this thread I am locking it.

Any cost implications are between myself and my manager and nothing to do with a public forum.

I have received the information I needed so I thank those who participated and provided an answer without starting an argument over who is paying for the hosting of my server.

Thanks guys,

That is the answer I was expecting but not the one I wanted, it does make sense given that the S5 kicks out enough heat that my lounge is a toasty 21c without heating. I was hoping that if I left the back door on the cab open it would keep the temps low enough that I could run it on a temporary basis until the rack is moved to its new location in a temperature controlled server room generally kept at 18 - 21c @ 30% - 36% RH

@Jamphone I am interested if you could elaborate your response regarding it not paying for itself.

My work is allowing me to host this unit FOC in my test environment where all costs are covered (Power & Data) so my only cost is roughly £1600 for the hardware itself. Given that my current setup (roughly 1.3th\s is yielding me 0.1 BTC per week) adding a SP35 should yield me roughly 0.5BTC per week. I have to give my manager 2BTC for hosting (up front fee not a re occurring cost).

So providing that it keeps making BTCs for me i will return a profit eventually; especially if the BTC price jumps in price to some silly price again then all will be well.

The only way I can see myself not making money off this is if it needs to be hosted in our T3 Datacenter which comes with a £450PCM fee + Electricity, or if the BTC price tanks and never recovers.

NOTE: I am not rubbishing your response all input is very valuable to me but I am struggling to get past all of the people who say " you will never profit/break even mining is a waste of electricity. the difficulty is too hard" I would like a balanced argument on both sides.

Thank you again for your input.

Hi Guys,

I have been given permission to host 1x SP35 miner in my test enviroment at work which currently contains 5 other servers all pumping out heat into the comms rack in my office, unfortunatly it is not in a temparature controlled enviroment (yet). This should be fixed in the upcoming months where the rack will be moved to an air conditioned room they should also be upgrading me to a 30amp supply to my rack.

Currently the intake temprature on my servers are reading 38c and they will shutdown automatically if intake temp reaches 42c.



If I add an SP35 in this rack do you think it will push up the ambent temp up those magic 4 degrees and cause problems for my other servers, if it will how noisy are these units as I could leave the back door of the cab open in order to release some of the heat if required.

If things go well I will ask the boss if I can add a 2nd one in order to bring my # rate up to 10th/s
