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.

Quote from: SebastianJu on July 13, 2013, 02:36:35 PM 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.

Quote from: f.baasch75 on July 13, 2013, 10:37:34 AM 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).

Quote from: dani on July 13, 2013, 09:57:08 AM 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".

Are you sure the radiator is able to dissipate that kind of wattage (16 boards all together)? it was just a "dummy" configuration. if i would stick to cooling 16 boards with it, i would take the big MORA(slightly more expensive) and two pumps for most performance.

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!

Quote from: tigerbit on July 12, 2013, 02:29:54 PM Follow on question for the 16 board example: Connections? Is a manifold required either side of the boards? Else board number 16 in the chain will be getting some warm water cooling! Radiators llike the Mora have 3 inputs. How should the loops be best designed to make most efficient cooling. A simple chain of 16 boards sounds like a really bad idea. thats not correct. the difference in watertemp. at the 3rd and the 16th board is too low to make any difference. And besides that, my mora just has 2 G1/4. One Inlet and one outlet.

I want one of those too Quote from: fiktionist on July 12, 2013, 09:07:54 AM My MORA is ready! atm its cooling a dual Sandy Bridge-EP 8core Xeon Setup with two GTX770. The Mora is bored Fans at 700rpm and the air/water dif. is just like 8°C. http://shop.watercool.de/epages/WatercooleK.sf/en_GB/?ObjectPath=/Shops/WatercooleK/Products/25120 Looking at this setup it makes me want to water cool my whole computer. Could you do us a favour and maybe point towards a place that explains watercooling well? German is ok for me, others might prefer english. What I don't want to see is basically me checking everything, realizing that there is still something I need and then realize I have to wait three days for it to arrive... that would be unprofitable i would stick to this http://lifehacker.com/5940236/a-beginners-guide-to-water-cooling-your-computer

Hey Sebastian, könntest du mir gerade ne PN schicken?
