Latest SS by Johann

[johann]

Been working on this latest singlestage, turned out really nice

Specs:

Compressor: Danfoss NL11F
Evap: Chilly1 rev e (Courtesy of Gray Mole )
Captube: 2.8m 0.031
Gas R402a
Controller: G-Froster Xe

Temps:

idle: -59c
160w resistor load for 24hours: -42c
150w resistor load for 24hours: -44c

I expect to see around -46c to -50c on the evap with average overclocked AMD loaded Should be around -20c core with IHS on.

Thanks to Gray Mole for all the help! Also thanks to Chilly1 for this incredible evap.

Beautiful

It's great to things going well for you sir

No load and load temps are ideal, and the layout looks great

Can't wait to see that case come in and the final product, and I suppose this means we'll be seeing more of your work soon too

Gray

[johann]

Indeed there are a few more coming soon including a gpu freezer which is basically done

[MeltedDuron]

looking good! love the desuperheater too (gray can you do a couple of them on the vapo before SLHX? :p) Those are awesome temps for straight 402 as well johann

[kayl]

very nice
160w is big, can i have a look at how ya did the resistor load?

[johann]

Hey Kayl, thanks!

I dont have pics of the loadtester in current form but here was the original. Since then the surface was lapped to mirror finish. Also uses some heatpaste under resistors to make sure heat transfer good.

Also used to be around 185 watts but I swapped a 100 ohm resistor for 150 ohms to give a total of 350 ohms and 160w at 237v

Its insulated of course, the outside of insulation is always room temp so not alot of heat getting lost there. I suppose they can never be perfect but its close enough for me. A real CPU rarely puts out 160w anyways and there are also some heatloss there through the mobo so it equals out I would think

[Ssilencer]

Nice work Johann, nice temps too

[Shinuza]

I hope I could do as good as you done there

Nice job m8

[Fhqwhgads6680]

Wow Johann that is looking REALLY nice! very clean and professional! All around an EXCELLENT SS...keep up the awesome work!

[boardy]

Wow that does look nice mate. I see your not using the black conensor on this one?

Boardy

[johann]

Thanks alot guys.

Yeah Boardy I didnt use the black one as I had a little more space to play with and this one I used has a little better capacity so I can use a more silent fan to match the silent NL11f

[quintus]

nice job dude!!!
greetings

[bazx]

looks good J but you should be getting better load temps than that for the
parts used

[LukeXE]

I don`t think so, 160W dummy load is very big (it`s like >200W CPU), unit must have some nice power to hold this load.

Temps are very good, that same I can write about Johann`s SS

I agree LukeXE, I think you will see temps of around -50c on the average overclcoked AMD loaded, but nice thing is it will hold hotter CPUS like X2 and P4 to a nice temp

[SoddemFX]

Very nice Johann

I like your pipework and placing...

Tom

[yngndrw]

That's really sweet mate, good job.

[johann]

Little update..

I have changed resistors on my tester and it outputs 150w now, gave it a go and get around -44c loaded with 150w

Frosters have arrived Cases shipped and should be here before the weekend.

[fatty]

Very nice work mate well done !!!!

160watt dummy load is like 200watt cpu??? all the power is transformed into heat in electronics so 160watt heat load=160watt cpu.

[johann]

Very nice work mate well done !!!!

Thanks! Today Im building a sligthly smaller one. Similar setup but 9cc compressor and smaller condensor. Will be interesting to see the difference

I have written this, because I had red this in few posts on polish forum, so If I`m wrong, I`m sorry for mistake

Also I am not sure but I am pretty sure that 150w is a good load to tune as few overclocked AMD CPU's generate 150w. Some x2 maybe a little more but in general it is less than 150w so tuning for 150 then a little more is a good average.

I may be wrong also

[Haar]

How did u make this one? What kind of pipe bender? Is it Ø10mm. pipe?

And nice work.

[johann]

That was made using a PVC pipe. It is 1/4" (6.4mm I think) soft dehydrated copper.

Simply take copper and bend it around any pipe or round object. Sometimes I use my MAPP or Deodorant bottles
