Members of the competition, please post your ice batch shots here
I have no proper thermometer, will my G-Froster count?Quote:

With rules like Fhqwhgads6680 wrote we rather wouldn't be having ghetto auto-cs like there were in previous auto competition :D
I think that 200W resistorload is a bit overkill, 150W resistorload is much bigger load, than eg. A64 Venice on 1.8V and clocked to 3.3 ghz :rolleyes:
@johann : You're going to use SC21CL ??

I am in, just to participate.
Embraco 1/2 HP compressor

did everbody suddenly forget that r4** gasses aren't suitable for autocascades? I see lots of people with r402a.
I sacrificed one of my son's Ice Lollies for this :D

That REALLY shows how bad the original UEI probes are, both of them showed about the same at 3-4c. Get's much worse at -50.

Swapped over the replacement probe from the Fluke to the UEI, much better. Still way off using 2 probes tho :rolleyes:

And my son, very scruffy at that time of day, who coincidentally had just eaten of the Ice Lollies I stole for my icebath :D
Cheers

LOL @ Grey
Nice looking young whipper snapper you got there.
oh...dang didn't realize that...whats the reasoning, is it cause its blended or what? still learning about autocascades...its what I had that was a good gas so I figured it'd be ok. I guess then 507 would be the best first stage choice then...thoughts on this? thanks for letting me know.Quote:

If we remember back to first autocascade competition there were only a very few ppl that actually got their autocascades to well autocascade.
Apart for chillys autocacade that he recharged, no one else actually owns a autocascade that’s cooling their pc.
I had my autocascade running on my gpu at some stage and was quiet hard to get it to hold nice loaded temps to that what ya get on a king single stage.
So asking ppl to cool a 150W-200w heatload is not going to yield temps much better temps than an average big single stage.
I have some issues with heatloads and how ppl construct them. Firstly the resistors arnt all the same size so when you attach them to a cold plate some parts of the resistors run hotter than other parts. Depending on the contact mount between the resistors/cold plate and evap head will also greatly effect how much heat is actually being removed.
Also how can we tell if the dummy loads are even being powered??
Also some ppl use 3mm cold plate between the resistor load and evap, other use 25mm copper plates, some use aluminium some use copper etc.
There is also the risk of ppl electrocuting them selves.
These little dummy loads are live mains voltage, and if not build correctly, someones gonna get zapped. I am yet to see ppl ground their dummy loads.
The resistors that are used in these dummy loads are only rated to 50w each. So ppl using 3 resistors and running them at 200w, well the resistors are over powered and are gonna burn out in time.
For the last autocascade competition we kept it real simple, lowest noload temp was winner.
Since these coolers are meant to be used to cool cpus, why not judge them on best loaded cpu. To be fair cpus must be run at stock speeds loaded by OCT with a pic of temp probe and screen dumb of die temps after 30mins.
Ppl can tune their autoacasdes on dummy loads if like, and could also OC the crap out of their CPU to see how the autocascade handles high loads.
But keeping the heatload to a stock cpu means heat loads of around 80w.
And we all know that cooling a t stock cpu isn’t that hard and gives some nice temps, both evap heads and die temps.
Why not just remove the rules and have the judges make there own assesments on catagories including temperatures and such? Removes a lot of the complexity.
We're having a fun little autocascade competition where we all just want to get autocascades running, we're not fighting a war.
Well either way when it comes to the Guide lines (rules)... gota to fix my Omega for calibration first.
But I'm in with a KAJB-010E-CAV... refrigerant will prob change as time goes on. Have to do some testing before I could make that obligation.
/em from some noob in the background, "Rules are made to be broken"
"I second that"
As for the equipment I'm using, it's subject to change, but right now I have a 1/2HP matsu and I'll be using R22 in the first stage. Second stage gas is undecided as of yet, but It probably won't be CO2.
anyway, here's my ice-bat shot:

I can aready see Redwolfs AutoC :D No one can compete with that monster when its ready.
BTW I have grounded my loadblock :) And I got my last autocascade to hold decent temps with 180w resistor. The real problem was to keep the whole compressor from freezing in the process. Well 1.7hp and 34cc does have slight advantage over 1/2hp and 12cc :P
@Kayl - some nice ideas.
@Redwolf - so, I will add you when you`ll be sure about participate in competition, ok ? :)
Maybe Chilly1 will said something about testing of working auto-c, on what load ite. He`s the judge, so maybe he will have some nice ideas like Kayl.
r4** gasses seperate in the phase-sepQuote:

So R507 would be separated too :( ...it's very similar azeotrope mix like R404a .Quote:

Ahh that makes sense....well luke, put me down for 507 then instead of 402a.Quote:

btw i was always concered about putting a probe into a liquid. If the liquid is slightly conductive does that effect the Ohms of the probe? (which in turn changes the temperature)
Very good point. Trying to cheat Gray Mole? You sly little devil. :P
So what are the limitations then?
wow, with Unknown Road running around barking at people over what gas they use or saying that he won't get involved unless the heatload he wants is used, and getting slated for using an 'Ice Lolly' for my icebath, it's sure sucking the fun out of this 'fun' competition.
Take me off the list.
