There is no one currently building cascades for the general population. I on occasion will do them but I really do not have the infrastructure to be doing many cascades unless they want to pick it up. As for those single stages if I am not wrong they use around a 40mm spiral evap which is fine for some legacy benching but you will want a better evap design for modern chips. The koolance chillers do not really hold up to a proper custom chiller that costs around the same amount for something much much more powerful or something a lot less that is the equivalent power
I didn't know they still made them... but I guess once you're in this cooling bracket a SS is the way to go as I've seen some previously sell for $1500-$2000...
Unless you are shipping across an ocean there is no reason for most single stages to cost 2k. Average cost for one built with all new parts is about 1k and then maybe a few hundred for shipping. But in my opinion there is little reason to go with a single stage unless you only do cpu overclocking and never ram or gpu as well or if you have deep pockets and want to go with a single stage and a chiller. I just finished building a dual compressor chiller a few days ago that held close to -30c at 1200w load for half an hour so 3x gpus and a cpu no problem. You may gain 10-15c colder temps with a single stage but you are going to be limited to cooling a single component
Single stage is OK but would like to get cascade .
I have never seen any advertised and although I have an AC ticket , just don't have the time or patience to build one .
I have seen that the temp transfer to die isn't the best .
Seem to lose a lot for some reason.
Now onto the million dollar question of how one actually gets a cascade in AU. You will not be able to buy one new that is out of the question almost 100% but there are some things going for you. First you live in a hot place so AC's are more common which is a good start. Second, last I checked you guys have some of the best gas suppliers around for specialty gasses so getting r170, 23 and 1150 would be easy. Onto the bad stuff, you can not legally make a cascade with the typical fist sage gas but there are some work arounds that are not hard to do if you are willing to get a bit creative. The hardest part by far for you is going to be sourcing some of the more specialty parts but lots can be made at home like an oil separator and expansion tank. Condenders can be hard to find outside of the EU but luckily there is a cheap way to do it, do a hybrid air and water cooled first stage and a water cooled second stage which will allow you to use the common 120mm condensers off aliexpress that have worldwide shipping. If you go the route of building one I am more than happy to help

The Koolance is actually a very good chiller . Build quality is second to none. It's small , very efficient and works . It should be possible to get to 20 below ambient .I see -5 on the block with room ambient around 15 to 20 (air con blasting because Western Australia gets very hot). The settings go down to -19 but can't see you getting it that cold. I have a stack of different blocks for CPU and GPU so can basically cool everything with it , including RAM .
I mainly use it on the test bench but it looks pretty good when used in a case . See below with my HOF set up .
When it's set this low , antifreeze is a essential
PS sorry about all the pics but I love cooling porn

george: sis family now had the covid all around but now ok. 4th vaccine awaiting. Here been good this far with three vaccines, otoh, the 1st wave I suspect I caught something, took 6 weeks to have the systems going, family was ok though. Just staying at home.

Vinster: Where my parents lived they made that change also. I think it was because the storm drains were backing up and people started charging the city for upkeep on the section between the house and the city drain. with no proper demarcation they stopped
Aug 12, 2022 20:52:39 GMT -5
austin86: Vinster its odd here, gutters can't go to a storm drain anymore but they can drain into the street right next to one lol. I think its more of a city property vs residents property thing, IDK all I know is the town asked us not to drain my gutters into it.

austin86: zila1 dirty sumps are the worst, my parents sump is always dirty and if its not the sump is the drain from the other low spot in the basement that goes to the sump thatch dirty, they can be a lot of work
Aug 12, 2022 8:16:01 GMT -5
Vinster: for storms, we can still drain to the storm drains. there is a storm culvert in my back yard. everything drains to it (except sewer obviously)

Vinster: son is clear so far, baby's day 2 went overall well.. no puking today. just had to keep her fever under control. shes a tough little cookie...
Aug 11, 2022 20:58:10 GMT -5
Vinster: Thanks, 1st day for me starting to feel normal (Day 7)... Partner is still really sick (her Day 10).. Wife can't taste or smell... (her day 4).. daughter feels normal now (her day 10) but she had it the lighest...

zila1: I just want to keep everything in tip top working condition and clean at all times. I can't stand a dirty sump pit.
Aug 11, 2022 18:54:49 GMT -5
zila1: You are very fortunate to have that system grandfathered in. They are very strict now as to how and where you can drain storm water. I had a similar situation at my old 100 year old home.
Aug 11, 2022 18:53:30 GMT -5
austin86: I'm amazed I not been told to remove it, even more amazed that it works. We were told we can no longer have the gutters drain into storm drain witch I get. Its a big home and it was becoming a problem with all the rain we get here.

austin86: In my case my home is on a slight incline and whoever built it rigged up a gravity fed system that feeds the water table into a storm drain in the street. I been told I can't do anything with the system as its grandfathered in and is not longer legal.
Aug 11, 2022 14:19:41 GMT -5
austin86: zila1 My home is right under the water table and does not have a sump. There are some ways a round it granted they are not always a option or all the great.

ShrimpBrime: Dogs are always crazy in their own yard. Mine are no different and why I need a fence so bad.
Aug 11, 2022 7:08:04 GMT -5
zila1: Now they can't see me anymore cause of the fence. Her dogs are crazy.
Aug 11, 2022 0:34:25 GMT -5
zila1: But she put her new fence right along side my damaged fence. We both inherited problems but watcha gonna do? At least those trees are gone and now she has a nice privacy fence there. I'm glad cause her dogs were trying to eat me.
Aug 11, 2022 0:33:44 GMT -5
zila1: First she had to have a bunch of trees cut down around the area she wanted the fence. They were all in my yard working because the trees were growing in my fence and she wanted them gone. Now my fence is a mess.
Aug 11, 2022 0:31:10 GMT -5
zila1: ShrimpBrime: it never ends Jon. Just when you think you've got it all done something else happens. Home ownership is real. The lady next door to me just had her fence installed. She told me she's been waiting all summer for it.
Aug 11, 2022 0:28:24 GMT -5
zila1: Vinster: Oh my gosh I am so sorry you have that in your family. I will keep good thoughts for you. Covid is just horrible.
Aug 11, 2022 0:26:20 GMT -5
Vinster: only person without it is my 15yr old boy. he's keeping to his room isolating from the house plague. 0 out of 10... would not recommend... even for the weight loss.
Aug 10, 2022 23:28:57 GMT -5
Vinster: having covid sucks... whole family has it.. it's been taking 1 member at a time... we've been fighting in for 2 weeks and today we lost again today, my 9 month old now has it... this shit is awful.
