3.6W needs the D12SH, 24W the FFB... But the difference in airflow volume is only 150m³/h to 322... I wonder why.
Not everything in life is linear my friend!

funny thing, im in this hardware/overclocking/modding business since approx. 2001 and the best fans ive ever had were the Yate Loon D12SL - 120mm, 1350 U/min 28 dB/A 28 m³/h.
The D12SH (last letter h for high, l for low, m for medium) were pretty good too (2200 U/min 40 dB/A 149,51 m³/h) both must be around 5€ per Fan.
If i would put my miner into a datacentre i would recommend high performance fans, with as much airflow as possible.
You could also put some Delta Fans into it. (FFB1212EHE 120x120x38mm, Doppelkugellager, 4000rpm, 322m³/h, 59dB(A)) but i doubt, that the fan port on the bitburne is ready for a fan that draws itself 24w of power
But i think burnin should say something about the production heatsink, since the choice of the best fan mostly depens on the surface/material of the heatsink ...

@burnin... what fans are included? Can you give some details? Name or rpm, airflow volume or similar...
Hm. didnt think about that yet. Are those fans really better? What settings should i take a look on? I mean it shouldn't be some trash cheaply built in china but it should cool the miners the best they can. Of course with automatic fan-speed-change. Airflowvolume? Whats important?
Yes, thats why i look for other countries with lower electricity. But the main reason is... i cant really host it at home. It will reach limits of home electricity, it will maybe be strange too to have such high electricitiy bills (in usa you could get a raid because they think you raise hash), its unsecure at home (miners were stolen already) and the price for electricity is high too. So datacentres look like the only solution to me.
If its true that watercooling isnt allowed then watercooling isnt a solution for me. The only thing i would try then would be to form a real tight airtunnel for my miners. From fan through heatsinks. This way i hope to optimize the heat dissipation through air. But i still search an appropriate material for forming the tunnel and fasten it. It shouldnt cause shortcuts and should be flexible and static enough.
In a datacentre, I guess nobody will care about the noise of your miners.
So you could just go and use high performance fans above 2500RPM...
Nice explaination.
I think before burnin didnt test the advantages of watercooling its all speculation. Only when there is a reasonable advantage it would make sense to go that route. So i hope he will test it.
And i wait for an answer from hetzner if they would allow watercooling in their datacentres anyway.
been there, done that. in 2011 they did not allow it ... i think that especially in germany its not very clever to host miners in datacenters due the high costs for electricity.

if you wanna have watercooled systems in germany try it and give them a call

with 2 boards i would go for sth. like this http://www.aquatuning.de/product_info.php/info/p15479_Bundle-Alphacool-NexXxoS-XT45-Full-Copper-240mm--Standard--mit-2x-Yate-Loon-D12SL-12-1350rpm.html
with 4 boards that http://www.aquatuning.de/product_info.php/info/p15480_Bundle-Alphacool-NexXxoS-XT45-Full-Copper-360mm--Standard--mit-3x-Yate-Loon-D12SL-12-1350rpm.html
until 4 or 5 watercoolers this pump would do its job pretty well, if more than that i would prefer the laing.
http://www.aquatuning.de/product_info.php/info/p13342_Alphacool-Eheim-Power-1046-12Volt-Vollkeramiklagerung-II--4m-F-rderh-he-.html
i think its safe to say:
Bitburners <100w = 2x120mm Radiator for silent cooling
Bitburners <200w = 3x140mm Radiator for silent cooling
Bitburners <300w = 4x140mm Radiator for silent cooling
everything more than that, take sth. big like the mora.
and if you are totally whack and want to overclock the shit out of these poor bitburners, take that http://www.aquatuning.de/product_info.php/info/p4742_Durchlaufk-hler-Hailea-Ultra-Titan-2000--HC1000-1650Watt-K-lteleistung--.html but thats just for the hardcore guys.

Intriguing. Looks very nice.
Couple of questions:
can the boards still stack easily with this back to back cooler arrangement?
can someone with some watercooling experience give me an idea of the BOM to cool 12 boards?
12x80 = 960W
It seems like a great idea but I'm worried it will prove expensive when you add in radiators, pumps, fans, reservoirs. Is this going to need £300 investment on top of the cooling blocks?

it honestly all depends on the waterblock price and number of boards your going to get..
Can you translate this into cost per miner? For example "Watercooling a bitburner XX would cost X more €/$".
as burnin said earlier, the cooler will be for two bitburners and the price difference between aircooling and watercooling should be at ca. 15euro per board.
simple math.
15€ per Board for the watercooler, 280€ for the watercooling itself.
the more bitburners you cool, the "cheaper" it gets.
Watercooling is nothing for beginners, if you have no clue about it, leave it. One leak can kill your bitburners instantly!
Well , do you have recommendations for alternatives for 2 - 4 Boards without that Mora and that Laing ? Doesn't make sense to me with a small number of boards.
Nice explaination.

what do think about this radiator?
http://www.ebay.de/itm/KUHLER-WASSERKUHLER-OPEL-CORSA-B-1-0-1-2-/370838293132?pt=DE_Autoteile&fits=Make%3AOpel&hash=item5657af4a8c
it is much cheaper and it can easily be mounted outside the house

car/industrial radiators are optimized for high airflow, so if you dont have a high airflow, its not working so well ... PLUS you have to get g1/4 fittings on it somehow ...
@eheim1250, same problem with the eheim compact, those pumps are not suited very well for so many coolers ... the only pump suited well for this kind of job i can recommend is the laing ddc (plus).
maybe this pump will work:
http://geizhals.de/eheim-universal-1250-790-vollkeramik-a397389.html?plz=&t=v&va=b&vl=de&v=e#filterform
1200 L per hour

Those liang pumps cost around 70 bucks, why not use an eheim compact 1000? It provides double the flow at around 20 bucks each, plus you can put it into a bucket where it will be quiet?
the problem with the eheim is the fact, that it doesnt work very well if there are very restrictive coolers in the chain. since you will have 8 coolers and a big fat radiator, thats going to be very restrictive, so the laing is the better choice because it has simply more "pressure".
I didn't consider that, thanks. Any other pumps running on 230V that you can recommend? I don't want to hook up more on my PSU, plus I think those 12V pumps are more expensive than 230V ones that are widely available for aquariums etc.
Any recommendations on a silent, powerful (and cheaper) 230V/12V pump? Anyone?

the more bitburners you cool, the "cheaper" it gets.
Are you sure the radiator is able to dissipate that kind of wattage (16 boards all together)?

EDIT: Hmm this thread is talking about 1000W dissipation, so maybe it is doable (depending on the OC of the boards)

You'll just end up with a higher delta T....
