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?
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...
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.
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?
imgur.com/a/97Rzhad I'm ashamed with how messy the benching setup is but it is what it is. 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.
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...
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
funsoul: Now ya'll know one of my other "hobbies" lmao

funsoul: Based on your statements, I'd not be at all surprised if the soul of your dad is one of your actual greeters on that side

funsoul: Losing someone we love is so painful. I don't know much but I do know that when your time comes to make the transition, you'll know you're together again.

ShrimpBrime: If it counts, I hope it's a very long time before you meet your dad again Eddie.

zila1: Strange. I hear my dad's voice all of the time. Like he's watching over me. Sometimes I hear that strong voice of his calling me. And I hear his laughter. It sounds so real. Like he's standing right next to me.
Aug 15, 2022 23:51:11 GMT -5
zila1: I can't wait to see him again. One day God willing when I finally leave this place I will see my Dad, my hero again.

zila1: My Dad was all over Europe during WWII. Served under General Patton. My Dad kicked some ass. It's no wonder he was always such a tough bastard and could drink anyone under the table. I miss my Dad.

zila1: I am feeling very emotional tonight. It took a year but I finally received a copy of my Dad's military discharge papers. I feel very proud of him and I also miss him very much. On the 21st will be a year since I lost my Dad.

ShrimpBrime: Thanks, I appreciate that! I only left because the pay scale was too low. They considered me as a Tech 2 last time. Which I'm beyond that and they know it. Diesel Tech and welding fabrication is my specialties.
Aug 15, 2022 20:45:21 GMT -5
funsoul: That's fantastic! Good for you! Glad they're giving you what you need
Aug 15, 2022 20:22:01 GMT -5
ShrimpBrime: Actually going back to a previous employer. I left on good terms, the pay was too low. This time, they are making up for it.

funsoul: Beautiful! Hope you're off to better

ShrimpBrime: Nice and easy re-entry. Day 1 of the last two weeks at current employer.
