This unit was built for mllrkllr88 with the request that it be as small and as quiet as possible and as a result has started my water cooled line of single stage units. The unit is a 1/2 hp rotery with a chilly1 evap, it is designed for use on legacy gpus and should hold up nicely with up to quad cores and maybe hex cores. Unfortunately due to size and budget constrictions of this unit it will probably not handle the new 10900k at full load for more than 30 seconds or so before it gets above -30c. Here is the unit and the idle results. I am going to be load testing the unit over the next few days and will post the results of the testing. imgur.com/a/byEWRmR |

Interesting an intercooler for the condensor is it efficient compared to a normal sized rediator and fan?

Interesting an intercooler for the condensor is it efficient compared to a normal sized rediator and fan? I have found it works better than a normal condenser as it can handle r410a without an issue on a small system like this where as it would be hard with an air cooled single stage. There are a few downsides though. I have to tighten up the superheat to about 1-2c instead of 4-6c to make the the compressor stays cool as it does not get airflow as it would with an air cooled system and it requires the user to already have a water cooling loop or to buy a water cooling loop. |

So when do you start to ship world wide? you get something like that dialed in, you're going to need an assembly line...

Vin Currently shipping is just going to be north america as I am not sure what the best way to prep these units for overseas shipping will be but I have a few ideas that I will be trying with chispy's big 2 or three stage cascade in 2021. As is I can not ship ones that are air cooled but am looking into shipping options for those. |

The rest of the world is 220v I know you have 220 split phase so you are building 220v units?

Vin is just in Americas hat, not like its really horrid shipping.

Vin is just in Americas hat, not like its really horrid shipping. going over a border kills...
even with shipping from friends I have in the US to pay duty tax... and it's never the same amount... So I usually avoid it at all costs..

Shipping for this is only 80$ across the country and is looking to be under 100 to Canada. |

I just sent a case and a bunch of computer parts to my buddy up in Windsor recently, only cost me about $90USD, I mean yeah that's higher but guarantee the weight was more than that chiller. Those Be Quiet! cases with tempered glass are heavy and I left a lot of my socket AM3 watercooling gear in it for him as well to play with. Anyhow, I will be keeping an eye on this mythicaltech , always loved this stuff. |

Just did final load testing before shipping the unit and here are the results.
Test 1:
38c ambient
480 rad with only one 120mm fans
2600k at 1.58v set in bios to give close to 1.55 under load
Evap temp after one run of r15 -25.3C
Evap temp after one run of wprime 1024 -24c
Test 2;
24c ambient after I turned on the ac
480 rad with only one 120mm fans
2600k at 1.58v set in bios to give close to 1.55 under load
Evap temp after one run of r15 -37C
Evap temp after one run of wprime 1024 -35.2c
Overall for the size and price of the unit it isn't terrible but the main pro of this unit is that it is not much louder then the pump and fan for the water loop. At room temperature it should handle quads very well and hex core chips for shorter benches like r15

that's awesome.. can you post a picture of the setup?

The mounting was a piece of scrap wood with two ln2 pots on it to keep the evap on place on the board. The pump is a cheap fish tank pump in a cut up lemonade bottle. In July I am going to be doing a big 1.5 hp single stage and a 2x 1hp co2 cascade and will be doing full build logs for those units and will post them here. Unfortunately this unit isn't going to be able to handle the 10900k for long benches but the big ss next month should handle everything under the sun for the next few decades and the cascade will be instant dry ice. |

I've got an entire pallet of compressors and 110 ft of suction line coming so I will be able to bang out builds as soon as someone orders it with only a few week time from ordering to shipping

I like that little one looks good.
What size compressors you getting?

I like that little one looks good. What size compressors you getting? 1hp r2# roterys which I will use for my standard water cooled units and I will be getting 1.2 hp ones for my autocascade chillers down the line. I am looking into getting secop 18cc reciprocating compressors to make dead silent cascades but that won't be for awhile as moq is 15 and that is almost 2500$ which is not currently feasible. I am also looking into getting these tiny 1.5cc compressors that are the size of a soda can that I am going to make into really really small single stages for ram and chipsets. My end goal is to have everything under the sun for phase available in one place but for now I am focusing on my tried-and-true 1hp single stages and prototyping more exotic things like autocascade chillers which should beat dry ice for temps but stay within the apprentice league. The big project which is ending up taking a lot of my time is the ln2 single stage which is currently working but it can only be used for about an hour before it dies so I am experimenting with different ways to get oil circulate at those temps but it is a slow process that is limited by how many free acs I can find to sacrifice for testing |

ah, so the water loop is the heat exchanger so you don't need the large hot side rad.. interesting...

Vin Correct, unfortunately for every 1/4 hp you need about 120mm of rad so for my big 3+ stage cascades or dual compressor single stages I will need to do a hybrid of a small 120mm 100mm thick air condenser and a mora 3 to cool it as it would otherwise require huge rad setups that most people don't have |
