WTB budget SS

[Mythical tech]

I am looking to get a budget single stage phase change unit. I am located in the United States east coast.

[Mythical tech]

Bump. 

[SparkysAdventure]

I'd say use SearchTempest to comb through Craigslist and you might find an old SS somewhere.

[Mythical tech]

There is nothing in about 500 miles from me. Still looking

[Mythical tech]

Bump 

[Mythical tech]

Still looking. Also willing to trade.

I have a HC500A I’m looking to sell. Has bypassed thermostat for sub zero cooling. 

[Mythical tech]

Still looking. I don't need anything that can handle insane loads just something for people at my colleges oc club can lear and practice with.

TBH its going to be expensive, and hard to track down. probably beter off perfecting your DICE game.  I know there are some on the east coast, but the problem is only one guy really made them or makes them, and he does the insane stuff mostly.

you might be best off looking for a dead one on ebay and trying to refill or fix it. since you are at a college, Id even consider building one yourselves. The hardest part to get ahold of is gonna be the cooling head but I think someone still makes those in EU and itll be a lot cheaper to get ahold of than a whole system. you can get a deep freeze compressor off ebay. The info is out there if you look hard enough.

 

also I feel anything single stage is gonna have a tough time on modern cpu packages. if they aren't tuned and maintained properly especially so.

[Mythical tech]

@Random Murderer I have thought about building one but I have never welded before so it will take some time before I feel comfortable making one. I will mostly just be using the single stage for ram/small gpu cooling because i am picking up a cascade to replace dice in a few days.

Also this is going to be a game of patience. phase change hasnt been popular for quite a few years now, and even when it was, it was EXPENSIVE, and between shipping, damage, gas fees. a lot of people just threw them out or burried them in their garages

 

you might have better luck over on xtremesystems

fugger is the go to guy on phase n that's his stomping grounds

[Mythical tech]

My budget is about 400-450 and I have seen some go for less so I think I just need to be patient.

Your best bet is to join an active team, and hope someone has one they will sell. I searched for ~1.5yr, then got lucky and was able to buy one from a teammate. I then subsequently sold it to another teammate about a year later. Usually rare items like this are always offered to team members first before listed at the forums.

I would recommend you look into building a window a/c water chiller setup. Its cheaper, and you can build one immediately instead of waiting for an SS. Done correctly you can get -25-30c coolant temps. For reference the small SS I had ($400) only did like -28c idle on 8700k.

[Mythical tech]

I have a dual ac chiller that gets down to -48 with three 400 watt TECs inline but the unit draws so much power and is incredibly inefficient though it is good for multi gpu. The main problem with it is that it is hard to move back and forth to my apartment and where the oc club meets. 

[Random]

i'd seriously consider building one yourself then. It may be a hundred more or so than you'd want to spend but I don't think people make new ones. I have been around the forums for quite a few years now, they really only pop up once a year. and even then a lot are broken.

if you aren't confident with your skill, practice or find someone who is because I was friends with a guy who built these and designed the head most people used said it was really easy. only problem really is getting the gas IIRC

and if you can do an ac chiller with all that I bet you could do a phase way easier

@Random for the gas my place of work has 15+ 25lb of r407a that I could probably get permission to use some of. The problem with doing a phase is I can't weld in my apartment, I am looking into getting a membership to my local maker space so I can make an evap on a cnc and find someone to help me learn to weld.

[Random]

thats the part that pretty much everyone just buys, I think they are for sale for around 100$. they were last I checked. and then you are just brazing after that. which isn't much.
if you can get the gas and access to the filling equipment you are kinda set, thats really the biggest waste of money.

 

 

... hmm its been a long time since I looked I guess and I don't think that website is up anymore. I would open a new WTB thread just for the head, maybe contact some people on XS. Fugger can totally help.

keep an eye out on ebay too maybe?

but its definitely going to be a challenge getting that, or a phase. these things just aren't popular anymore. LN2 is too cheap. these are loud n bulky.  and Overclocking in general is just a lot more expensive than it used to be. The demand isn't there anymore I guess

@Randomfor me ln2 is 5$ a liter so for pretesting it is helpful to have a phase or two. I may just setting with using my cascade and getting a fish tank chiller for people to learn on.

I am surprised that's the best price you can get LN2 for, especually with college/ uni help.

I got it for about a dollar from a welding supply shop. I think airgas is cheaper

[Mythical tech]

@Random that's the problem, the college does not have with ln2 costs because we are still on progress to get official recognition as a club so all funding is done by donations by our small member base. For ln2 we get it at a welding supply shop, there is an airgass but they quoted me at 10$ maybe if I got copies from others who bought from airgass they would price match but the welding shop refused to match their competition. I am also the only one with a dewar so it isn't worth it to drive two hours to go l someone else for ln2.

I can deliver you the most difficult parts, assembled and ready for installation (evap, suction line, mounting kits) and provide some guidance about the rest of the parts which will be needed.

The work which you need to do:

- mount all the parts on the base plate, make some electric connections

- bend a few copper pipes

- braze the pipes, the most difficult part is to braze pipes to the compressor, you'll need quite powerful torch to make it properly

- charge the unit with gas and tune it for the load, to be honest it's good to have a load tester, but it can be made from cartridge heaters for the cheap + copper part, which I can also prepare

For what it is worth.
There where 2 units for sale on local Dutch market
1 Little Devil PC-V2  and a DIY Unit.
 

Don't think he sold them.
Can always ask if you fancy shipping and changing power socket on them.

[Mythical tech]

@bartx do you think this compressor would work if I changed the oil. I happened to get it today free from work and it is supposedly still functional. I would have to use a step up convertor to run it but I already have a 2kw one so as long as there are no issues using a step up then I will most likely be going the diy rout. Depending on how far I get with milling my own evap I may be buying one from you Bart. If anyone has any tips on how to change the oil that would be great. Also a cheap Manifold Gauge suggestion would be helpful.

From a quick search it looks like 3.5 hp might be a little high but if it would work that would be amazing.
