This is my KNC Mercury happily hashing away at 143GH, 91C.

Notice the custom book-based thermostats and mandatory thermal "overlay insulator".

The PSU is stuffed in there to get the temperature up, the beaglebone fans are OFF, main unit fan is ON.

Its stable and it works, though. Dunno for how long, realistically. Huh

I hope so. I only see fire hazard all the place in that picture: obstructed fans, close to books, over a carpet, with a pillow...
If that's for real, I wonder how long will it take to catch fire and turn the room into ashes.

the pillow is a cooling pillow. look it up, one that size is capable of dissipating about 700W, which is more then enough for a jupiter with the fans unplugged  Cheesy

Here is my rig:
1x Antminer V1 with the secondary board being a V2 replacement (bitmain absolutely nailed it on the RMA process and got me a replacement within only a few business days)
1x Antminer V2
1x Bitfury August Starter Kit w/ 1 H-board
1x 730W modular RAIDMAX
1x 600W Modular Corsair

Total hashrate of about 435GHash/s. The units are on a small table underneath another table. The antminer with an orange fan is to replace the obnoxiously loud fan that came on the unit. the second antminer did not suffer the same noise issues Smiley

Oh that's one of those Cougar fans, I just bought 2 of them for my case since the stock ones died after 4 years of continuous use. They're really nice and quiet with the rubber mounts.

they really are. I am strongly considering replacing the other stock PWM fan with one. They look AWESOME and are very quiet, but unfortunately have lower airflow. (box says around 75CFM, while the stock fans must push over 100CFM).

BTW: anyone have good liquid cooling ideas or methods? It would be pretty sweet if the antminer boards could be placed into immersion cooling, but i know that they would require a radiator capable of >400W for each antminer which i imagine is costly and semi-complex to install

AFAIK liquid cooling (waterblocks) are not really ideal for ~200W (per blade) spread over a large area. The blocks would tend to be expensive. They are usually made for higher densities. For an ant you would likely need to get slabs custom built... then mount the blades onto it. I did see some early avalon threads where someone got custom waterblocks made... and used a chiller to cool the water.

Immersion cooling could work, just need to figure out how to keep the solution cool...

I think liquid cooling is waste of money... unless you can overclock it to the point of justifying your investment.

wow thats a massive aluminum heatsink lol. I was thinking along the lines of immersion cooling (single or dual phase, though single phase would obviously be cheaper and simpler to build and seal)

if it would work with the heatsinks removed, you could put 4 antminer blades (total 400GH in aircooling, ~900W) into a tank as small as [12"L x 6"W x 8"H] and have space for liquid to circulate. With the heatsinks, the width would be closer to 12".

I think heatsinks still needed for single phase.

The big problem still is how u gonna cool the liquid... You still have to deal with the same amount of heat to remove. Immersion is good for 2 things.
1) Have a buffer zone. If u generate heat in bursts, like typical computing, gaming, etc where you run it at max power for short times and not 24x7. You only have to deal with the average. - Not applicable here.
2) Channel heat elsewhere where you can exchange it more efficiently.

I was thinking a system more similar to the asicminer system, but i beleive that involves a sealed tank, and still requires either circulating the liquid through a radiator or having a peltier cooler for the gas state

standard disclaimer //

Immersion cool in baby oil (paraffin oil) (About $5 per liter not buying it in bulk), circulate with a quality car windscreen wiper fluid pump or electronic fuel pump. The reason for this oil choice is its availability and its not very viscous at all. These are about the same cost as a "gaming" water cooling pump but far more better quality and more robust: just get one from your local car junkyard they should have millions. Also, fuel pumps are designed to handle non-polar fluids (which includes oils) so they're more likely to be compatible with the oil than a random watercooling system pump which may contain materials that will disintegrate / dissolve / embrittle in the oil.

Get yourself a portable air conditioner, or external unit of a split system air conditioner and have the gas removed by a licensed refrigeration mechanic (of course). OR, a second hand car radiator. All of these should be able to handle over 3 kW of heat assuming you put some decent fans near it. Even with silent fans you can remove immense quantities of heat thanks to their ridiculous surface area.

Tubing should be silicone (medical) tubing or fuel line tubing that automotive and some hardware stores stock. Fuel line tubing costs about $7/meter where I live for 2 mm thick walled stuff (Masters Home Improvement centers, Australia). Medical tubing is usually even more expensive ($10+ /m) and not necessarily any better and you'll probably find stock in your country is monopolized by companies who specialize it selling it.

Before installing the system for real, you should place it over some kind of sealed basin or container and leak test the entire system with its full lengths of tubing for at least 1 day. However as some materials are semi-permeable to oils you should think about testing it for at least a week if you want to be cautious.

If you have access to a quality router with metal routing bits you can easily make your own waterblocks with a moderate ammount of fore planning their design. It should be made from aluminium. If your have a router or CNC capable of doing this work then you don't need to be told where to get metal from. You can buy silicone sealant strips or rings, and silicone sealant type glues from any half decent hardware store to make the seal.

If you dont want to make your own 'oil blocks' then you can buy the relatively large (and relatively dodgy) Chinese eBay waterblocks. I have heard reports that they CAN be used with oil.

It's also worth keeping in mind that although its VERY hard to ignite paraffin oil without preheating it to at least a few hundred deg C, it can burn. And if it starts to burn and you have a few liters of it you have a extreme problem. I recommend that any high-current cables passing through the air-water interface are sealed inside of a metal tube so that if there is a fire in those cables then it cannot contact the oil interface. It is almost impossible to get a resistively heated wire to ignite oil if it is fully submerged in the oil. It can only ignite if it manages to heat the entire oil mass to its autoignition temperature or if it can come into contact with the air-water interface. I recommend you test this for yourself with a small qty of oil and and old ATX PSU.

You start off talking about immersion then you talk about machining 'oil blocks'

I understand the concept of both cooling systems, oil immersion and using blocks with fluid, but why would you bother running oil through blocks when water is a) cheaper, b) more efficient at removing heat from the block?
