got 2 new heatercores

[saaya]

wich one do you think will perform better?

a lot of small alu fins
medium sized alu tubes

[saaya]

less and very thick copper fins
small copper tubes

[saaya]

here are both with a 120mm fan

[saaya]

you can see that the copper one is quite a bit larger and a lot thicker. i will compare both and keep the best one for myself and build the other one into the watercooling setup of a friend a made for him :D

got em both from ebay, paid 10€ with shipping! :banana:

[Dissolved]

The one on the LEFT looks nice :D


Edit: Sleep Makes you smart doesnt it?

[Teus]

the left one is a great radiator!

[kommando]

I've got the one on the right, the one the left looks liek some seirous ownage.

[saaya]

the one onthe left is basically like a huge bix , the one on the left hasa bigger fin surface are though i think... will get some 12mm hoses and test them with the 120mm deltas that just arrived :D

[saaya]

went straight for the copper heatercore with 2 120mm deltas (expected them to be much louder) on it.

idle temps barton@2.5ghz 2.1v 31°C :)

diference between water temp and roomtemp is not meassurable in idle! :banana:

Saaya,

Do you know what car or truck that copper rad came out of?

What was the CFM of the Deltas used? How were the fans configured on the rad?

What pump and with what line size? CPU block in test?

VERY impressive results! ! Which leads to lots of questions on how!;)

Thanks:toast:

Edit:

Also a very nice O/C you have there!

[saaya]

no idear what car it comes from. bought it on ebay for 1€ :D :D :D

if you want i can email the seller and ask him what car it comes from. http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=2461401091&category=53932&sspagename=STRK%3AMEBWN%3AIT&rd=1

the deltas have an cfm rating of ~100 and are pretty silent for that huge amount of air they move. i mean they are anything but silent, but for that cfm... should be around 40db less than a geforce fx 5800 :D

2 fans on one site pushing. since the rad is whopping 6cm thick theres not too much air moving through it. i just ordered another pair of deltas so i have a push/pull config.

im only using a termal upgrade probe i plugged into my a7n8x. its not THAT accurate and sometimes jumps from 24 to 27 and back and stuff like that, but the average temp it reads in 1minute is pretty close to what the temp really is.

with this termal probe i could not meassure ANY diference between air and water temp and the water in the res (wich is still open) is very cold even though i have my cpu and gpu in the loop.

so why order another pair of deltas? well i wanna mod them to run with 5v (they run with even 2.5v!) so i get it as silent as possible. if that doesnt work i can still run them at 12v and and hang the rad outside my window and have enough headroom to raise the vcore to 2.5v :D

each of the fans pulls 8W! im glad i bought some fan grills ^^

res (100L) inline value pump from eheim (1000L/H) ->rad -> cpu ->gpu (9500@9700pro stock) ->res

the res was filled with 35°C warm water when i started! it dropped more and more during the first minutes when i hook the rad to the system close and then exactly to roomtemp.

mobile 2400+ @12.5x200 2.1v (max stable without the rad was 2650mhz where the water would heat up to 37°C+ running prime overnight! :eek: ) hope i can get higher with lower temps

im using a cheap-o spiral cpu block immitation i bought for 25€ on com-tra.de , has 8mm in and outlets (yeah i know, but what do you expect from a 25€ block :D)

the average delta between water and cpu temp is ~15°C

right now with an open window and fresh spring air in my room i get following temps:

roomtemp: 16°C
water temp res: 16°C
water temp rad: 16°C
cpu temp (internal cpu diode) 30°C
mainboard temp: 25°C

this is idle. with ut2004 load i get "load" temps of 32°C :eek:
priming now...

EDIT: what delta does a white water have with a 1000L/H pump? 8°C? would have around 24°C cpu temps then :D

[saaya]

update: prime load 36°C

as soon as i stop the test the cpu temp drops to 35°C in a matter of seconds

damn max stable is still 2650mhz :\

hmmm maybe its my memory or vdd, i think i set it back to default some time ago as i was to busy to oc and just wanted a silent system...

[Craig]

Thanks for the details Saaya!

You need, and deserve, a cascade or White Water for your system, along with some 1/2" lines.

Great temps, what more is there to say? Who could say how much they'd drop with 1/2" lines and a White Water.

As I'm in the US and you are in Germany don't bother with e-mailing the seller. I've a listing of all the Fedco rads made and sold here, yours isn't in the file. Is most likly from a truck or something that isn't sold in the US.

Congrats on a really great find.

[saaya]

damn my board is dying? cant get 210 fsb anymore... wtf?

[saaya]

i lowered the volts on the deltas to 5v and they are ABSOLUTELY SILENT! :eek: and they still spin pretty fast and i can still feel the air running through the heatercore, almost as strong as with 12v!

those deltas are GREAT! 120mm 95cfm 2800rpm 2.5cm tall i think, bought them new for 8€ each on ebay! def the best choice for a heatercore rad i ever heard of!

lots of cfm AND silent! :up:

EDIT: my heatrcore kicks some major 4ss indeed! even with the fans at 5v the load temps wont go above 36°C!
