Jinu117 SS Worklog (vapoli, UFO, etc)

[eagle101]

hi jin can you give a hint of the results of something new....

[jinu117]

Here you go
Due to some major change in component, not quite to the perfection yet.
Ambient is tad cooler today at 19c right now.
I decided to go reverse on this to minimize some waiting time on temperature settling down

240w... I am actually quite surprised. In real usage I do expect number to be higher though...



230w... Well, what can I say...



200w...



175w...



100w...



0w...



Still need to test on higher ambient temp and tune more but this looks promising so far

[DagoDuck]

Hi jinu,

well done, nice results!

Some argued that -42°C at 180 watts is not possible. As you can see, they have no idea.

Best regards,

Hey Dago,
Du bist mir noch was schuldig . Hier rumposten und EC nicht mehr sehen lassen - super Einstellung.
Du weißt genau das es um den Lasttester ging, das es möglich ist denk ich schon. Sry for the german text nothing interesting in there .

Hey Jin!
Nice results! What refrigiant did you use?

[jinu117]

R507 Too bad it is flooding back at 50w.... bleh... I need to retune some more ...

[Creek Tha Gray]

ok so system up and running with a temp video card @#%#^

so im at 3.2ghz at 1.45 volts
just running windows at im getting on the lcd a temp of -30 to -29 bouncing without playing games or video just web pages and basic stuff. i will try a game and post in a sec.

ok so at the setting playing gears of war and cpu only using soemthing aroun 60% of all 4 cores unit temp on lcd was at -27C after exit of game back to -29/-30

update at 3.6ghz at 1.5 volts and 100% load for 1 min using OCCT lcd temp was up to -24c / -25c all other system temps from the mobo had no change they are way off to around -14c. the old bios would show same as the lcd on the cooling unit.

jin plz let me know what you think at last when i said some thing you wanted to see load so i have it here for you plz post back asap.

[Creek Tha Gray]

ok at 3.8ghz and 1.5volt vcore unit is at -27C room temp is 26c at unit inlet.

[jinu117]

I get strong suspicion unit's temp probe is at wrong location again... -_-;
Do you see any change in the bios temp that goes above 0c, etc? The evap temp you told me is right around where you would see positive temp from system monitoring to begin with I belive...

PS) I am still in CES so I will be kind of unavailable till end of week unless I happen to drop by like now Sorry... but it's hactic out here.

one first note %&%*^^& i want to be at CES

and second note there is no change in temp using any sytems monitors

will the K-type probe work better and what is the range i should see

i get paid in 2 days and will order one then.

any plz link to any info from you about your CES time


ok so here we go testing tonight is

with NB at 1.61volts cpu is at 1.55 volts
fsb is 390mhz or rated fsb of 1560mhz
cpu is at 3.9ghz stable occt at 30min
temp on cpu is some where equal or below -22c jin unit temp is at -22c during the test.
NB was at 21c for first 8min or load then down to 20c for the last 17min or load and room temp is 24.6c

the unit was at -22c and during load unit back down to -27c / -28c
in pc software showing -7 on first 2 cores and -14 on second 2 cores no change for compleate test.

There probably already is small short temp probe (unfortunately, will most likely have to open the case slightly to use it). But k-type will work much better for sure. I've always had not so good time with those LM probes unfortunately with the evaps that are used due to placing it in awkward position.

CES was busy for sure.

[Creek Tha Gray]

so the k type is positioned better? / in the same area?

and i have played call of duty 4 and no issue with unit a 3.9ghz
for some odd thing the system will not post past 3.95 and this is stable.
new bios could help

will order k type temp unit.

[jinu117]

They I believe are position at same place (RunMC did that part). But it doesn't move around as easily so I am sure it will be more accurate
As for not posting beyond that, maybe want to check with OC portion of XS for some tips They are quite robust in this regard

[jinu117]

Well here is something bit different
Silver V2000, bit different plumbing order... Silver does have it's nicety for this more than I thought... (think this is first silver v2000 I've done after so many units...)



What I really liked was the hdd bay on this one... Funny enough, this is something I asked lian-li distributor to make it for me while back and first time I finally get to use it... lol. Matches with V2000 better this way after all.



Sorry for delay in shipping this... I've been running around like headless chicken as of late.

[n00b 0f l337]

Any autoc updates?

[tim-]

what a waste of space on that SS

you could easely fit a 4hdd bracket below psu if you just planned it a little more.

[DagoDuck]

Hehe, I like the color, too. Not bad, but as tim- already said, there is even enough space for the power supply. I am also building such a unit and it fits fine.

[crfracer290]

Looks great Jin, can't wait until it arrives

[Buckeye]

Gah ! I need to stop looking at this thread and reading it over and over and looking at all the nice pic's

[Moc]

Any autoc updates?

That would be in interesting.

[jinu117]

Not much on Auto-c to be honest, priorities dictates such that I didn't have chance to work on that one much. last test was around -65c @ 250w. Still need to spend some time figuring out charges.

[jinu117]

It has been a while since last time I posted a SS build. This time some differences from usual unit...


Yup, new evaporator. Takes more effort brazing, etc but I've had some good fun with this design before on some testings. This is actually bit more advanced version of some prototype runs I've been going through on evap.

Evacing... going to take a while since I forgot to put the valve core remover -_-;

[{.bLanK} GoD]

Good to see you around again Jinu. It's a pleasure seeing you're work.
Do we get to see inside your new evap? or are you going to keep it a secret?

[jinu117]

Sorry, for time being, I am going to keep it to myself.
As I am planning to get into production of such units, last thing I need is someone to verbatum copy all the time I spent figuring things out and just make it before I hit the market.
So far, results are promising. Certain design factors of evaporator is to get rid of suction accumulator for higher load system (pita to deal with for insulation).
Overcharged (it starts flood backing around 80w right now), 250w load holding evap temp is at -37.7c and load block at -18c. In comparison, heavily modded chilly1 evap would do 230w at -32c and load block at -8c.
(Load block is closer to what inside of CPU temp might be like)
Cap tubing was made tad long for the load to start with so I might not have to put accumulator still by adjusting cap tubing length.
Heat transfer characteristic is right on target for this one Even surpassing that of cryostar I tested last time (not by much though probably in 1-3c range).
I am crossing my fingers that cap tubing alone is enough for this unit (specification of tuning is for 230w... I might make it go higher if I see possibility without adding suction accumulator). After all, this unit is for 24x7 usage. Suction accumulator is not a bad thing to have, but I just don't like having them (for sake of cleaness, etc)

PS) I really never left.... just been too busy to have active participation in forum... all I would do is come, read select few topics and read pm, respond and than get back to business...

[{.bLanK} GoD]

Fair enough, I fully understand.
In fact I am privileged enough to know a few Daikin secrets, our service manager has a Daikin prototype hot water heat pump in his house "testing" lol It has some very interesting features, wish I could tell ya'll.

[Gunslinger]

Hmm, I work for Daikin America Inc.
