The gas ir R402a...

tnx

Nice job. Very well done and clean, wierd condensor though!

[Moonman]

Nice system! :toast:

You will get a PM with my adress. :fact:

Now get that thing on your opteron.

[Athens[2004]]

Ya realy nice and clean job as all your singles ive seen /. Can this fan [1X120mm] keep condeser cool ?

[wdrzal]

Am I mistaken or are you using k probes and have your meter set for T probes???

Looks like 3 seperate condensors..??

It looks like a T in the display and these looks like K types. Blue is T and yellow is K IIRC.

Nope, i believe that SS is headed towards my Venice relatively soon :stick: :D :toast:

Great job little devil, love the heavy duty condensor!! :fact:

Thanks

A very pleasant work, a good temp. It hurts that it cannot get that gas. If not, without a doubt it would put it ;)

tnx

any info about the catube lenght? low pressure? ;)

[runmc]

Could you take a picture of the other side of the condenser so we can see the tubing.

Looks nice;)

You might want to look into that.:D

o/t but I have got blue, yellow, white with blue strips, and green - all K type :)

The gas ir R402 captube (0,7mm) is 230cm long.... Is it good or not?

tnx

I think it is fine, but -68c is too low, check you thermometer please, see that the display is showing T instead of K

[johann]

I see -6hg lowside, it will not achieve -68c. I may be mistaken but with that pressure and 402 I see higher temp normally

[Blaster]

loaded temps are a much better reference :rolleyes:

Opteron 146 1.6V @ 3100Mhz full load

R402
-67,990 T [°C]
-0.68 P [bar]

R507 at the same temp is also about ~-0.71 bar

[Ssilencer]

At least on the tablke I have it says almost 18hg for -68c on r402

[[ZIZI]]

I have a question...

Does running the system with a really low preassure result in really low temps without load, but really bad temps when under load...due to the heat capacity and load bearing capability of the specific gas?

Thanks
[ZIZI]

[Blaster]

low pressure => low mass flow => low heat transfer

higher the load the higher heat transfer u need...

Ok, -46.3 full load is more realistic and not bad (is under load isn't it?)

[LittleDevil]

update 1.72 bios 3500mhz full load -41.7....

[d@rkn1ko]

you have good contact? I see 5°c :cool:

[mtb856]

That's a typical error that software temp programs will show when you have sub-zero cooling.... that's why he has the meter, it's a lot more accurate.

[jinu117]

that cpu temp depends heavily on exact cpu, mobo, etc. Only time I use that for reference really is if all my setup is same other than cooling unit to get an idea which setup is cooling better.

1.72v bios vcore = 1.67 real vcore

a 3.5ghz opty @ full load gives -41C is very good ! :toast:
at this heat load i would expect around 0 temps... so +5C cpu temp is ok.

whats your bios temp ? and idle temp ? (cpu)


great setup !

[LittleDevil]

bios temps -18... idle on metter -48

tnx
