That's all.
Thank you for your attention.
Welcome to discuss it! Thank you!

To the managers of this site and this forum:
May I link my website address with the Signature logo? I'll very appreciate your kind.:bows:

[Blaster]

good job

but plz reduce the size of ur fotos

[runmc]

Welcome to Xtremesystem.

Please resize your picture:eek: :eek:

[Xeon th MG Pony]

well this IS the extream forum, lol but ya at least knock em down to 800*600

[epion2985]

Wherer are the details? Compressors? Gases? Metering Devices? Heat Exchangers? tisk tisk.... :slap:

[CoolingMaster]

>"< Sorry about that.
This is the first time I post the infos on this forum.
If I made a mistake,please inform me and forgive me.
And may I link the site address with the signature logo?

The pictures are really over-size .... XP
How should I do? please tell me.

The brand of compressor: Umbraco
Gases: R507

[\Karting_freak]

R507 on both stages? must be R507 and R1150

[epion2985]

Dont worry about it, just busting your chops.

Umbraco? Maybe you mean Embraco? I have a few Embraco units, never heard of Umbraco.

[guess2098]

i hope it is better than my 3 heads......

[fatty]

Hmmm says 410/508 nice

[CoolingMaster]

Sorry, both they are Danfoss. It's my fault.
The first compressor: R507 is used.
The second compressor: R508 is used.

[Athens[2004]]

Do u build those unit by your own ?

[CoolingMaster]

to Athens:

It's a modified product. Made by our company.
We can accept the manufacturing-order of players ^^

[CoolingMaster]

By the way,

The heat exchanger is Tube Refrigerant Condensers

[gundamit]

power:ultra 500w Wow. Hard to imagine this PSU didn't stop the OC party. I got one of these dirt cheap after rebate, but didn't bother to test it on my rigs. It went into straight into my brother's bland media machine.

BTW - Nice CPU. Not bit by the bug, or at least not very hard.

[Unseen]

Nice work there :)
I see u r using r508
Can u plz tell me the evap temp at load?

thanks

take a look over there:)

[Ssilencer]

-14c core temp at -89c? something is not right there.

[Carlz0r]

-14c core temp at -89c? something is not right there.
I'm guessing it's meant to be -41, and is just a typo.

[Jort]

3.75 ghz ain't a all day frequenty too remember.

but it will be a type prolly:)

[Unknown_road]

or the evap just isn't that good?

[Ssilencer]

It is almost imposible to do -14 with -89 in evap, I think you can even use a stone evap and get better temps :D

[Weee]

If you look at the photos of the desktop after the benchmark, SmartGuardian is showing -16, so I definitely don't think it's a typo. Great CPU MHz if that cpu temp is right though

[Xeon th MG Pony]

the onboard sensor is usless do not put ANY weight on it, only use an external prob to validate. befor my bios update my procs where running at 300C on one machine, after bios update one they where at -1, third update they finaly got "Close' to the right area @ 30C so don't take what the soft ware says with any real weight. (Unless some one has confirmed on several systems it is indeed some what accurate)

[Ssilencer]

we all known how the dfi ultra -d measures, so we know the temp references.
We don't agree much lately Xeon :D

[Athens[2004]]

Dont look the cpu freq.... Cpu freq doesnt mean anything ... Maybe this cpu did 3.5g with water so 3.75g was quite easily with sub . Something's going wrong with the load temp definetly -12 -13 @ from dfi monitor i had with a single stage @ Venice 1.88vcore @ s&m load... / Maybe the only explanation with the big difference between---> core temp --- > and evap temp is that the evap doesnt sit correctly or wrong apply of thermal grease..

I agree with you

guess what, a cpu @ 3.7 ghz puts alot of heat. air,water,phase.... you still got the generated heat :)

but the coretemps i don't know but -15° on 3750 ghz i still nice.

modded mach2 @ 3.1 venice and 1.79v around -7 ~-5° stressed:)

where is dumo, he can tell us;)

edit:

you guys i don't know but when i tell you something its based on what i saw.

check this out!
So far so good, only 57 mem. controller still shy with >-75C...

[C-BuZz]

those load temps look pretty close, my 146 @ 3.5/1.65v idles around -17c with Kayl evap @ -42c. Loaded it hits +10c & evap on around -36c.

I initally thought I had a bad mound but after remounting it 10+ times with exactly the same results I figured it was as good as it was going to get .

Time to remove IHS ! I had 3700+ @ 1.79V -26C loaded read by mbm5 on jin's cooler with IHS off..........

[Ssilencer]

Well, -26loaded at 1.79V is extreme! for a single stage, jinu did a really nice work on your unit, I think you have to send him a bonus :D

Vcore is a lot more important than mhz if we are talking about heat a delta evap/core of 70c is far away from being efficient.
Nobody take temp measures with smartguardian... just speedfan or mbm5

Oops, my mistake, -16, I had a typo, however this is still comparable to the number being shown by a cascade!

your right about the delta but the cascade is prolly not as good as other cascade's.
looks like any temp shown is off because of the sometimes worse contact between the ihs and the core.

and we don't have many info on this big boy right now.:)

[piotres]

Thare must be mistake ...I think there should be -41*c instead of -14*c :)

[fatty]

Mine was doing -84 evap idle and -78 full load @ 3750 vcore of 1.7 something but my bios was reading -43 idle smart gaurdian was reading -50 odd????

[s7e9h3n]

~-70C Evap on the autocascade:

Or for a little more voltage, maybe this is a better example :p: IIRC, ~-68C evap:

There's significantly more load while in the bios than in windows desktop idle.

[s7e9h3n]

Not really ;) I had caught this thread when it started and noticed those odd temps. Thought I'd throw some input into this as something's VERY wrong with his core temps. Don't want anyone to get scammed (no offense OP). Now I don't know much about building a cascade, but shouldn't the second compressor be somehow connected to cooling loop instead of just sitting by itself? :p:

http://coolerexpress.org/images/2stage-72-20x16.jpg

[Carlz0r]

It looks like it may be connected through the middle divider, and the condensor is just blocking the view of it.

[CoolingMaster]

Hello,

I can understand maybe someone can not sure if this test report is true or not.
No problem we will entrust other site to test this product in the future.

But I think the owner of this unit was very satisfied with it. ^^
(This buyer is an European.)
