Which EXHAUST Fan are you using Citronick?    THOSE BAIKAL PRINTERS................OH MY, you need a bigger warehouse.  These print faster than you can store the money.   Too bad I wasn't able to get 1 in before they start setting restrictions.

@ Onefinecoin - Where do you live where it's 50C outside?  Holy cow.  You will need AC.  Sorry that's way too hot as the best you can do with open air / exhaust is to be able to match Ambient.  Even with Swamp cooler it will only drop the temp to where I believe is still way above what I would recommend for long term mining.  At that kind of temp, I think you either need AC or look for Hosting solutions.  However you mentioned that Power is cheap so just use AC.  They are printing so much money that it's not a concern right now.

@ ALL other, SHOW OFF YOUR PRINT STATIONS!!!!!!!!!!!!!  No need to CLEAN them up or Pretty them up.  ALL PRINT STATIONS are $EXY by Default.

@citronick: what is your outlet and inlet ? Windows? are they on 2 different sides of the room? What is the max temp it gets there in summer ?

@yun9999 - I was initially planning to completely close the setup with plywood or something and Pull air out from top (using fans ) and create inlet from bottom pushing air in, but now maybe I will build another rig right on top of this setup and push air laterally.

I just got my three Sapphire Furies delivered from Amazon, I plan on building with Furies the most as my electricity is very cheap. But the issue is they do a lot of heat too being AMD and Furious , so is there anything going to work other than AC when its 50 degrees outside  !!???

Yup I am also looking into something like tarp/canvass type solution - like the what you have done.

My group has barred me from doing any experiment during these critical times s anyways - LOL.

I have penned the ideas down on my ideas  -- no action needed at this moment because PRINTERS are busy working 24x7.

The air suckers are doing their job fairly well at the moment.

You don't really need permanent partitioning.  Hot air rise so even if you use TARP to partition without impacting structures, you can see huge improvements.

yeah _ that's the principle that I was trying to achieve but its not that easy since the warehouse is leased and I cant do permanent partitions, walls etc. etc. So the best alternative was the big ass fan method -- but since that is a a few thousand dollar solution -- I took the 2nd best alternative which is that sucker/blower fan x 2 -- it works fairly well and its mobile, meaning I can move the sucking end of the hose to where I think has the most concentrated heat area. I think I need to borrow yun9999's thermal camera - LOL.

only a small farm lah - I am using a that blower/sucker to suck out hot air - currently it works well because I can place the sucking end of the hose to where heat is concentrated. But when its too hot outside, I have to turn on the 2nd blower which I just installed.

So the warehouse have now 2 suckers and 33 printers - LOL!

yeah PRINT $$$ is on top of the priority list !

@citronick, warehouse across the border ? well, as for ventilation, best is to suck it hard than blowing directly, just figure out a way for the air to flow & suck all those hot air out. take note of noise, depending on type of exhaust. but make sure there is some sort of dust proof/filter on the fresh air inlet.

back to printing $ & work on new projects.

Indeed, the secret is to have a small space, separate where your cool and hot air circulate, and increase the air circulation, if you leave everything in the "open" you will have trouble to regulate the temperature because you will be unable to generate enough negative pressure except if you buy really big ass fans (and im talking the kind of type you can see in chinese farms that are 300 inch wide at least), Another thing, remember that the hot air goes up, and the cool air keep being down, if you don't suck out the hot air, the cool air can't come fast enough to your rigs, and the heat build up.

@Onefinecoin - It really depends on your open air layout and how many shelves.  You can do a semi Server Case / Open Air way by blocking the heat on each shelf with a piece of plastic or heat resistant material.  Then you can blow the heat from the rear to the front where you can exhaust them all out vs the heat heating up each shelf as it goes up.  

@ Citronick - Nothing to be embarassed about.  Money is ALWAYS $EXY!  If you have 33 Rigs, it shouldn't be hard if you're able to control the Exhaust and cuts in roof or walls.  Section off the Big ass warehouse into a smaller section.  Do what is recommened above for OneFinecoin.  Server case is not a requirement if you can control what holes and where you can put things.  I have to do it my way because I can't exhaust it out via the walls as I have bricks.  But if you can control what you can cut / install, just section it off and put a decent Exhaust fan and it will suck out all the heat before it can even build up.  Harder when it's trying to do that for the entire warehouse.


But for now, PLEASE DO NOT INTERRUPT THE PRINTING PROCESS!  Let me go fix my Printer JAM issues again.  Dammit, jam so often.

Almost all of my rig are open cage in a fairly big warehouse.

Currently I place box fans below to move air UPWARDS since hot air moves upwards.

I use a blower to move air out of the warehouse. A second blower/sucker will be setup to help further reduce overall temps. Currently temps at 37c, hope to get them to 35c.

I am working on moving the rigs to rackmounted like yun9999's project but I have halted all development work for now... because rigs are busy ZEC mining and printing money  

@yun9999 -- as you can see -- I am embarrassed to show my rigs because its messy as hell. But its working hard for me so no complaints.

For Open style rigs, what is better approach, blowing the air at the Cards from the front or pulling out the air from top ?

You will need something that is good at pulling / negative pressure.  Something like this with ducts may do the job for you.  You can add more as needed.  They're not that huge.

Well my gear is sitting on the roof (build a nice 30m² mine up there   )
The only way of getting air out is drilling a hole through the roof and embed a plastic pipe.

Usual pipe size is 125mm or 150mm diameter.

There are so called In-Line Fans to put directly into the pipe (clean and easy) but my fear is that they aren´t able to pull enough air. So I need a radial vent probably and connect it with a flex pipe to the roof pipe  
Fresh / cold air is coming from down the house since I will leave a grid to the 1st floor.

Maybe someone here did this already or has the straight tip for me  

omg...how much money you spend for all of these..totaly...please give m3 info...

@YSLYUNG - You're spot on. The bigger 10" Orion fan moves a lot of air for it's size and yes you can power then directly from the server PSU fan pin on the breakout board or 6PIN via making your own custom cable or connect via Molex.  Lots of options.  You can even wire it to a cheap 12V AC adapter.  It's very quiet and since it's so efficient you can actually use 1 each to cool per rig if you really wanted to.  A bit over kill but at 24W?  Why not.  I can also use these behind my Server rack or move air in path I want.  They're industrial quality and are designed to work 24x7.  MarkAZ usually only recommend the best and I'm super happy with these fans.  But we just have to keep things in perspective that it's still a very tiny 10" FAN so don't expect miracles but it will move way more air then a 20" Box fan.  I am going to install these on the top section of my shed, I would expect 3 of these to outperform 5 of my Box fans while consuming less power and make less noise.  The flexibility of these are endless since low wattage and can be powered by our ATX PSU / server psu / AC adapter. 

Regarding the PICO - You use the PCI from the HP server PSU to power the PICO or do you use the AC Adapter?  What I find is since we're using PCI power for the riser from the server PSU, even when you shut off the rig, the GPU is still getting powered to the riser as the server PSU is on.  This is why I use the splitter cable so when I am working on a rig, I just pull from that end vs from the GPU and riser.  This allows me to work on a rig without powering off the entire 4KW.  Not sure how we can get around this when using PICO and PCI powered risers.  For baby ATX, the baby ATX controls the riser and the MB so everything would be completely off.  That's the difference I found between the two.  Slight annoyance but I'm willing to sacrifice that for the sexiness and more design flexibility with the Picos.


@ onefinecoin - They sell these on Ebay and I buy from who Mark recommend which is Maria.  There's a lot of copy cat type fans, stick with ORIONs.    You will need to buy a pair of 254MM grill cover to protect yourself from getting your fingers cut off.  They're powerful but they're also very smart fans with slow start rampup to avoid putting too much pressure on your PSU when powering many up at once.  At $60 each, they are not cheap but each will save me over 85W compare to my Box fans x 8 = 680W so they will pay for themselves over time and I expect them to outlast my box fans as they are industrial grade.

@ Citronick - You would need bigger fans then these for pulling out of the warehouse but these will be great to push the hot air into the Heat wall or for funneling of open air rigs,etc.  I plan to buy more and do some cool things with them.  MARKAZ actually use 1 per RIG in his design.  Looks very cool.  Everything he build is meant to last forever.  Haha. 

@ TheDue - Not sure what you're trying to accomplish.  What type of Exhaust fan?  Will need more details.


@All - Seems like the bubble burst is starting.  BTC below 1K, Eth drop from peak of over 50 down to 36.  Sucks, was hoping for at least a few months of Bubbleness so we can ROI faster.  On the bright side ZEC is 76!  I've seen this movie too many times, that's why I hardly get excited seeing any bubbles.  I just try to savor the short moments.  =)

Still looking for an InLine Fan or something else to put in front of my exhaust that works quite well in / with a 150mm or 125mm diameter tube, any idea?

@onefinecoin- Tax free land... WOW, you are either in Middle East country or Brunei DS.

@yun9999 - OMG - what fans are those - looks like it comes from some exotic car/limo? Be sure to send pix when completed - I am looking for a big ass fan that can pull air out of the warehouse. Incidentally, I did get a call from bigassfan.com (LOL!) but their warehouse industrial fan cost me 2k! I told them I cant afford their big ass price! LOL - 

OP can you share the link to buy those fans from ? Also did any1 try the exhaust fans? the small ones that are generally used ikitchens & WC

Just to tease you guys, I don't need worry about taxes, as there are no taxes where I live. Its a tax free land

then how abt PS ON & PS OFF ? if mobo are powered directly by server psu then the mobo will always have +12V, not too sure how it works that's why i let the pico do the job for the PS ON & PS OFF & to avoid any accidental short circuits if it may or may not happen.

yep in some cases it won't even get warm, depends on each individuals setup, some put the whole bunch of rigs, psu, gpu and everything close & stacked together so that may have some accumulated heat & heats everything else up. just saying & do take note, a proper planning is always a good idea to start with when expanding especially cooling+exhaust.

since you have a monster psu the 4kw, just power those orion fans directly using the psu itself, you can even add a simple on/off switch instead of pulling out the pcie from the breakout board. let the pico rest heh . . . nice fan ! hook it up behind the rigs (2 would be sufficient me thinks), will suck all the hot air and bring in fresh & cool air over entire rig, psu & gpu. how's the sound of it ? i'm pretty confident it's not as loud as the small ones. can you do a short video of them running ?

yeah totally agreed, let's enjoy the bubble now & hope it won't pop so soon. faster roi/profits for most of us too.

tax ? hmmm don't even wanna think abt it too much as of now till year end or time to submit them, then let the P&L numbers do the rest.

Nah..............I have zero concerns.  Most of us are running Intel Celeron and the entire system is using 50W or less.   The Pico won't even get warm.  I'm using 80W Picos right now with no issues.  Finksy Pico is 160W and we're not even powering the CPU which is the biggest power draw for the entire system as the server PSU is powering it via the 6PIN to 4+4Pin EPS cable.  There's so much spare power left that I can even use the MOLEX on the PICO to power other stuff like my new FAVORITE ORION FANS!


You see this MASSIVE 10" FAN to the right?  That's an ORION DC FAN.  That thing move more Air then any box fans you can find and the negative pressure is insane for the size  Guess what?  It barely uses 24W!  The Pico will be able to power that sucker instead of using a ugly and wastefully weak BOX FAN that waste between 70-110W of power on MAX!  Special thanks for my MAN MARK AZ for the recommendation.  I Absolutely love this fan.  I added the grills because they are so powerful they will cut your fingers!    The way Finksy have it setup, you're not even barely pushing this Pico other than on and off.  99% of the load is handled by the server PSU.  






P.S These ORION FANS ARE SICK!  I'm going to be ordering lots of them for my $$$$ Makers


@ Tmdz  - The CHAMPAGNEs are paid for from the tax deductions.  Let's not talk about TAX, and boring economics.  Let's just ENJOY THE PARTY!!!!!!!!!!!!!!!!!    All we care about is PRINTING MONEY..................

I just want to celebrate our potentially SHORT BUBBLE.  DONT POP THAT BUBBLE SOONER THAN IT HAS TO BE.  These BUBBLEs are usually followed by TROUBLEs....................just enjoy it while it last guys.  Quit being so serious!
