I think I read it the same way jstefanop did. They state its totally self contained. Even with oil based cooling you still need to get the heat out, all the oil does is pull it away from the chips.
This video explains it: https://www.youtube.com/watch?v=Z_X_hgtlJpA
Unless I understand their post. The renders show no vent/fans.
EDIT: i re-read their post and they state Mineral Oil which would be different than the video I posted. But even with mineral oil you woul d need some kind of radiator or something to cool the heated oil.
Exactly but it makes the mineral oil loop self contained - it's still really messy and not sure if you can ship it that easily plus too pricey etc water us usually easier to do and maintain plus oil isn't really cheap.
All system is cooled with two separate radiators. Why 2? Simple - if we use 1 large instead of two, we get hot oil drain from first module to the second one(loop PUMP->Mod.1->Mod.2->RADIATOR-.PUMP). Temperature difference between those modules increases to 15-20°C, so first module is approx. 34°C and second one heats up to 50-55°C. With 2 radiators we get loop like PUMP->RADIATOR.1->Mod.1->RADIATOR.2->Mod.2->PUMP. In this case we can program both cooler fans to work separately instead of running them at one speed.
System needs no maintenance because we use oil instead of cooling liquid(which leaves a lot of shit on the internals of the radiators and pump). There is no need to change that oil because of such small electric load. Life of the oil at such load is more than 8 years.
Shipping pack will contain miner and 2.5L of the oil(in sealed bottle, with all necessary documents to pass any customs check).
With great pleasure will add a little bit oil to the fire: Small test video
