Black Mamba SS by Johann

[johann]

This SS I built without a controller as some people need the cooling and budget is a little tight.

Great 24/7 runner, the Electrolux compressor is nice and silent especially closed up in the solid DimasTech case.

Captube a little shorter for extra capacity with a good charge to hold a little heavier load than normal quite good. You sacrifice a little temp this way but still kicks the socks of a Mach or Vapo :mrgreen:

Fans are Papst 70cfm 220v. Great quality smooth running reasonably silent

Specs:

Compressor: Electrolux MP90FB 9cc
Evap: Chilly1 rev e
Captube: 2.1m 0.028
Gas R402a
DimasTech case
Fans: Papst 9956 220v

Temps:

idle: -52c

150w resistor load for 24hours: -37c

Completed:

Enjoy!

Nice!

Those 'Lux compressors are nice and quiet, and it's still making some nice temps too.

Looks great, Johann, I can't wait to get some of those cases too

Great work

Looks really nice that, great work

Oh yeah baby looking good. I like the Black better, may the gods favour me and let me have one soon.

[Johnny Bravo]

This would be great for GPU applications, hmmm decicisons decisions....

[johann]

Will hold a highly clocked AMD chip to -37c on the evap, I dont want to see the temp on a gpu, proppably in the region of -45c loaded with 120w

[maverik-sg1]

Be nice to understand what the temps on the CPU would be.

Hows about overclocking a x2 4800 1.68v 262*12 with it and showing BIOs temp.

I realise that the BIOS temps are not that accurate but as I look at BIOS temps now - it's the only thing that allows me to compare temps I have now with what you have built.

Great job, just wanna fair comparison of CPU temps.

Nowadays - is a 150w load enough? My FX60 churns out 180w+ fully overclocked on a SFI SLI-DR EXPERT board (volts set in BIOS @ 1.525x114% LDT volts set at 2.4).

Mav the rated wattage of a CPU is most of the time being a little over the top. 150w is fine for an AMD64, maybe 180-220w for an Intel as Thickbrit has found out, they are toasty little boogers.

I don't think Johann has an X2 either, uses Xeon's. This is theoretical load I believe, could be wrong though. Going on the 150w loadtester he is using, he is simulating a fully OC'd AMD64.

[maverik-sg1]

Even so - I already purchased one unit thinking it was better than what I had Would not want to fall into that 'trap' again.

The FX60 pumps out 110w TDP at 1.3v, I am at 1.68-1.72v and temps on the unit (R507 with Chilly revE head) I have now go well into plus temps (naked core too).

I think 200w is a suitable load to tune these units to, or too actually see some BIOS screenies of some high end kit so that people that only have BIOs temps to compare can look on, inspired what could be.

Sometimes it's good to invest in the hardware required to 'show-off' what the units can really do.

Boardy - When your unit is finished you will see what I mean, measure your evap temps using your load tester, then measure your CPU temps on that FX55 fully overclocked (1.75v LDT at 1.4v).

I guess what I am trying to say is that EVAP temps mean nothing to 'joe public' - BIOS screenies speak volumes

Please do not think that I am trying to discredit anyone's work here - you are all far more talented than me in the cooling business and I admire the work you guys do - just trying to help you guys make it easier to sell the concept of what I am sure is a killer cooling unit (compared to vapo's or mach's).

I don't think your unit has a revE on it mav, the revE's are the latest and your unit was one of the first R507 Chilly1 conversions from EP. May be wrong tho.

My unit is for GFX so won't be a very good indication of CPU stuff. I have 2x 80w loadtesters to simulate the GFX cards under load. 2x 7800GTX's under LN2 stupidly OC's only push about 100-110w. It's less than you think.

I can tell ya for sure that the AMD specs are not all they crack up to be. The wattage on the spec sheets is normally a guestimate and most of the time, over compensating.

We shall see though.

Looks great them cases are killer


Its great to see so many UK options way to go guys

[Leverpospade]

Looks nice, one day I too wish to sell phase units

Don't we all do that

@johann: Nice unit man. So when you power on th unit, you turn on the compressor, and when you have waited for a while you start the computer? No automatic? No temps to go after?

EDIT:
@maverik-sg1: Why do you want to see bios temps? Even a vapochill SE can hold a X2 at subzero temps in idle (or bios). It is first when you fully load your chip that you seperate the "men" from the "boys"..

Okay so really what we want to see are Superpi 32m and OCCT running in core 0 and 1 respectively at full overclock, thought that was a bit cheeky to ask someone to actually do that - but in retrospect, it's the right thing to do if you want a real world scenario.

[bazx]

when i built my first ss i used shamino guides

so after filling the unit hooked it up to a 57 oced it to 3.4 and then tuned the
unit using the bios for idle temps
and spi to get the best performance

i think also that there is a difference between tuning an ss for out and out performance and an ss for every day use

as this unit is for sale it makes sense to cover ya a$$ and make a unit that will
keep working and that is not living life on the edge

[maverik-sg1]

You are right Baz, I just wanted to see CPU temps compared to Evap temps for a comparison - I dont understand how EVAP temps really relate to the CPU, my mach says -59 under load on the display - 2 cores running fully loaded (210x16 @ 1.72v) show temps as +5 in motherboard monitor.

The comparison that Joe Public could relate to would be to see this unit connected to a similar rig running similar volts/clocks.

[fatty]

Well Mav seems how I regassed your first unit and it would hold -12 to -16 under 210W of heatload and your chilly1 headed unit would hold 210W of heatload at -25 to -30 degrees I find it very hard to believe that the new unit is no better than your old unit
And if you realy want to get into the whole how you purchased the unit I can get into that too

Also if Joe public wants a comparison my cascade at -84 evap was holding my fx57 at only 3750 1.7v in the bios on my dfi sli-dr it was -43 in smart guardian -53 so yes there is a big differance

[boardy]

Ok Fatty, lets not get nasty mate Swaying a little OT here I think.

Johann great unit mate, keep up the good work Lets see some cascade action dammit

Boardy

[fatty]

Yes very nice board but when some one slags off my work I will have a go

And sorry johann I hope you never have to deal with this sort of e

p.s great unit mate

[jinu117]

Bios temp means nothing to me actually... as it is only 25% or so of load it will put on dual priming, etc. (at least on AMD)

[maverik-sg1]

Fatty has a PM so we can talk about this in private, apologies for the thread trash

[johann]

Mav, I test units every day and for a builder of units you need a benchmark load, this way I know exactly what is expected temp and if something is wrong or not.

Gray Mole has found his 150w tester +- equal to a FX55 at 3500Mhz 1.7vcore (Correct me if Im wrong Gray) An x2 4800 seems to put out a little more heat than the 150w tester but not alot.

So imo 150w is pretty much a good average too charge too.

When I build a system to sell after, what do you charge too? What setups do the majority of people use, mmm AMD's around 3500Mhz +- ?

Some use intel, my units will hold any Intel chip solid without falling over, give it a 200w intel chip, sure it will loose temp but it will hold it and it will hold it solid.

This unit could have been 2 or 3c colder had I designed it for 150w only. If you read the first post, captube is shorter and the unit is running a good charge. This is to hold bigger loads well.

Im thinking of buying a Intel 930 dual core for "Real world" testing with a heavy load but then again I dont really care. I dont need to prove anything to anyone.

The happy owners of the units will supply real world results for me.

Wait one week, I have a unit shipping out here on Monday, the owner have a few different setups and he will post results. Then we can compare the real world results to my test results and see how they compare.

I dont post here for people to say wow or for some temp contest.

Fair comments Johann,

Thinking about it, you are right about the tuning levels required.

Like I said great job, loving the custom cases

Look forward to seeing the user results too.

I look forward too some results myself!

This great little cooler has been standing here for some months now, I removed the chilly1 evap for another project at some time and thought Id fix her up again as I really loved this smooth running machine.

The nice thing about this machine is little lower power consumtion than the normal 11cc and very very silent operation. Compressor cannot be heard even listening closely.

Changes from original

- Brand new case (Was needed for Gfroster)
- Dimas evap rev 4.1
- Gfroster XE controller
- Re tune for higher capacity
- Fans replaced (Blue LED in back and Panaflo on condensor)

Unit is little smaller than the normal NL11F machine but not atall small in performance, you still see 10-15c increased load temps in comparison to Stock Vapo LS especially on the higher loads.
