Quad core unit with @itor Evap

[Gray Mole]

I don't normally post the builds all that much any more, don't want to clutter the forum with the same thing over and over.

This build has @itor's newest revision evap though, and I was kind of a 'guinea pig' for it, as I don't think he's offered it out just yet.

Well the results are in, and I think that Rogard should count himself lucky, because he's gotten the best high load result I've ever been able to accomplish on a quiet build.

The specs...

Danfoss NL11F
Dimas small condensor (very free-flow, highly recommended)
@itor evap, latest revision with clear enclosure (best high load performance)
Unseen/Gsmaster 'Freeze pack' controller v1.7
Hybrid gas, blended for best low fan performance
2.9m of .031" captube w/slhx mod and accumulator
Dimas 'Staker' case in black
Led and EL wire mods
Front and rear alum. fans with blue Led

As far as looks go, it's pretty nice :) I did what I could to make sure of that.

It's the performance that really impressed me though.

I did most of the testing around high load and no-load so that it was compatible with any system but could handle any quad core.

0w at -53
50w at -50
150w at -41
200w at -38
270w at -34.8

That's about it, at just a hair over 270w it drops off like a rock, and it also starts to flood back at no-load if I try to tune it higher.

The other striking thing about the tuning itself was the captube. I used 2.9m of .031". I've alwys favored longer captubes with @itor's evaps and this time was no exception. I think that maybe I could have gone with 3.0m and still pulled off 270w but I didn't want to push my luck.

Time for some pics...

Well that's about it really.

I used the base of the acrylic mount to run the wiring and that ended up pretty clean this time. Overall the most striking thing about htis build for me is really the performance of @itor's newest version of the evap. I didn't think it could get any better but at 5-10c better results at 270w than his last head, that's really something special :)

Awesome job Gray, as allways!

When you say "hybrid gas"... can you expand a little on that? Is it one of the BOC "CARE" range refrigerants? I'm thinking of getting a bottle of CARE 50 (propane/ethane mix) to see what it's like compared with stuff like r402a, r404a, r507a etc.

[rogard]

Thanks Gray.

Awesome build and great service.


I do count myself as lucky and I cant wait to get this thing!

[Gray Mole]

Just the 'buzzword' I use whenever I blend a gas.

I call it 'hybrid' because I end up extending the glide a ways to allow for boht low fan speed for quiet operation and high fan speeds for better temps at high load.

This setup works at lower speed fans for the 270w result though, pretty pleased about that.

I use non-flammables for my blends though. Guess it's just something I feel strongly about it making stuff for other people, I'd hate to put them in any danger at all.

This one, to try to put numbers on the gasses, would be somewhere around 10% 134a, 40% 404a, 10% R22, 15% 407c, 25% 402a.

Strange mix when you look at the actual values, but I tried to work out what would give me what I wanted and then finetuned it as I went along. Having a few gasses to work with helps too.

The tuning process tends to look like 'spagetti junction' as i've got all the hoses connected to the gasses I'll use, which keeps any air out as I've got all the lines purged from the start.

I monitor superheat and subcooling pretty close now when I'm tuning as that's the key to a nice blend. I don't look to reproduce a blend as I don't think that's the idea. Every system likes a different ratio and mostly it's being tuned for a different 'ideal' so I just make it work for the system I'm doing.

Thanks though :) it's always fun to work with some new stuff, and this was a nice result.

Great results Gray I love your builds there some of the best builds ive seen and the information you give is second to none Im sure Rogard will it.

[HoriWanderFuLL]

Good for Quad Overclocking :up: i really love that enclouser Gray looks awsum...I like the way your coils are standing up gets good airflow across it..wandered when i would see someone doit..not that i look that often :rofl:

Also The gsmaster controller did you like it ?? i installed 1 other day i thought it was good...maybe just a heater pin would be nice ..i like heaters at idle ...

That foam inset in the evap head ..whats its description or name ..Any certain density you buy ???? i Pickud up some pvc today to make a few evap enclousers for my sons sys ..And a ls for weekends plays..

Very Nice build Gray:)

Your temp variation from idle to load are amazing. :clap: Where do you mount your temp probe on the evaporator?
Good job on evap and enclosure goes out to @itor

[Ssilencer]

Nice results!
I didn't know that it was uninsulated ones... :up:
I think that with for example pure r402 we can get even better temps if we are not worried about higher fan speed, am I right?
Well, looks like we can keep doing evaps for quite some time...
Oh btw, this enclosures were already channeled for wiring? I don't remember

[boshuter]

Very nice unit :up:

Can you elaborate on the
2.9m of .031" captube w/slhx mod and accumulator? I'd like to try some kind of slhx/accumulator, mainly to help control floodback at idle.

[gosmeyer]

Results like this have become expected with you Gray.
Very nice results and very good looking.
Well done!

(good to see you post)

[Jack]

Looking better every time!
Where are the photo's of @itors new evap? :D

[Clemmaster]

Why do you blend gases that are already blend of other gases to give the best performance? If there are so many gases that's not just for fun and blending R22 with other refrigerant is a bit curious : You use both R402a and R134a (one contains an amont of the other) so you reduce the R402a capacity, then you put an amount of R407c wich isn't very good in the LBP range (he's used in HBP, under -20° R404a is better)

With 2m30 cap tube and pure R22 I wouldn't be surprised if you get even better temperatures once loaded (R22 involve the highest COP you can ever get).

Nice build anyway :)

[dr.rafi]

very very nice temp and build:up:

[Dimas small condensor (very free-flow, highly recommended)]
is the use of short(small) with large pipe is better for high load unit?

[DarthBeavis]

Is that the same evap head going into my vap?

[inspector-71]

looks mint mate but......

I'm missing my games. :)

[Ssilencer]

Nope.
Remember that I told you gray was testing a new evap that I can`t offer you at that moment.

We have currently two evap models, the MA1 and the new CA1 currently on test by Gray Mole.

I'm very confident the new CA1 will be a even better performer for high loads, but I can't recommend it to you as we are still waiting to get feedback from him.

Anyway, send me a pm and we will talk about.:)

[DarthBeavis]

PM sent

[Ssilencer]

PM sent

Replied :)

The model name of this evap is CA1

I was talking to @itor today, we decided to discontinue the MA1 model and go with the CA1 from now on.:cool:

[n00b 0f l337]

Ya after recently testing the difference between a clean chilly1 evap, a clean runmc stepper, and a modified roughed up chilly1, its clear how far we need to improve evap design.

[dinos22]

how does this compare to current designs in performance

any relative comparisons?

Well, the only comparison available is from Gray mole, the MA1 was the best for high loads, and the CA1 is about 5 to 10c better...
Also, We (as a community) keep taking evap temps as the parameter to evaluate, when the real parameter is the cpu temp, I'd been telling this from more than a year, I hope some day someone will understand that.

The most important part is the delta T between evap head and processor, it is not difficult to get great temps in an evap with for example a 10mm base thickness, but when you check the proc temps you will find the worst delta you ever saw.

I'm sorry but i don't understand the jargon. I would just like a simple comparison to something older that's all. I am not having a go and trolling and don't think there is any need for an attitude. I just asked a simple question that's all

whether that comparison is on CPU or hotplate or whatever you use there...........I'm a layman and i need simple comparisons i can understand

Sorry it wasn't my intention at all.
I was just thinking out loud, it wasn't directed to you or anyone it was just my personal opinion.
We don't publish our own test as I don't think it is fair.

I just wants teh @itor and Ssilencer pimpage added to the V2-V3 pimpage in meh gansta-ized Vapochill to go into meh Gansta Rig . . .tho I may have to change the flames on teh Vap from red and black to blue and white . . .

Could a unit like this be used on the upcoming AMD quad cores?

Dude u need to call the psychic friends network to answer that one . . .

AMAZING work gray mole :D

Love the partabout taking care there is noo floodback :)
hate that sound on the LS :D

[CometMan]

did you actualy tested one quad in it?

[teyber]

i really like @itors evaps.... i like it a lot

[kayl]

nice work gray, were you able to find at what wattage the cooler drops off and stops working?? interesting to know :up:

[Zannema]

nice work :clap:
