Heatkiller Rev. 2.0 GPU

[Ricarus]

What do you guys think of this GPU cooler?

Here's a test with some nice pics

Looking good. It looks like the design of the silverprop fusion. I think that will perform very well. I checked out the link u gave. gotta love the tubing job they did on it. I've never seen a more restricvie 3 inches of tubing and barbs in my entire life.

[DaGoof]

VERY Similar to the silverprop. Like maxx said, should perform well.

[Ricarus]

It also reminded me of the Fusion, which is good a thing

And about that tubing, that is indeed verry bad... The germans don't seem to care much about flow :rolleyes:

[Arkangyl]

Does anyone know how much the small tubing and elbows really hurt temps though? I can't really imagine it being more than 2-3c

[quicksilverXP]

Yeah... doesn't hurt that much...especially for a GPU block..

[nikhsub1]

Not sure I like how the mounting bracket comes into contact with the water... what material is that bracket? SS? Al?

[EnJoY]

Where can we Americans by this block? ;)

[MaxxxRacer]

nik, the braket is SS from what i can tell. Alluminum doesnt look like that from my experiences.

Quote from the website translated with google..

" high-quality high-grade steel"

[EnJoY]

Yes, I too am interested to know that. ;)

The type of SS is very important here, some SS is fine, like found in the D4's, others are not so fine... I know I'm nitpicking, but I'll be damned if I have any corrosion in my loop...

[MaxxxRacer]

I know what u mean. I somehow doubt its ultra high quality steel. They didnt specifially say it was SS.

[Ricarus]

In german it says something like "edelstahl"


Die Halterung besteht aus hochwertigem Edelstahl und macht einen sehr stabilen Eindruck

I don't know the exact translation to english, but I guess it's good...

Edelstahl = stainless steel. Don't worry bout it. ;)

[MaxxxRacer]

ahh thanks for the info.. soudns good. but as nik said there are different types of SS. i have no knowledge of SS metals, as I ahve only dealt with al and ti.

[nikhsub1]

Edelstahl = stainless steel. Don't worry bout it. ;)
yeah yeah yeah, I've heard that before.

"There are five main types of stainless steel: ferritic, martensitic, austenitic, precipitation hardening and duplex."

"Corrosion resistance of stainless steels is a function not only of composition, but also of heat treatment, surface condition, and fabrication procedures, all of which may change the thermodynamic activity of the surface and thus dramatically affect the corrosion resistance. It is not necessary to chemically treat stainless steels to achieve passivity. The passive film forms spontaneously in the presence of oxygen. Most frequently, when steels are treated to improve passivity (passivation treatment), surface contaminants are removed by pickling to allow the passive film to reform in air, which it does almost immediately. Most of the ferritic and martensitic stainless steels have limited corrosion resistance in marine environments, but some of the newly developed ferritic grade s (often called “superferritics”) have excellent marine corrosion resistance and are widely used in applications such as tubes for power plant condensers." From: http://www.corrosion-doctors.org/MatSelect/corrstainsteel.htm

From one source, there are many more. Again, the TYPE of SS matters here.

[MaxxxRacer]

ok smarty pants... Well it seems we need to get this steel mount out of the block. possibly a silghtly thicker copper mount would do the trick.

[STEvil]

or titanium

[MaxxxRacer]

yah that is true, but you have to have special cnc machine to be able to cut titanium. normal steel bits wont cut it.

But i am pretty sure that titanium would do the trick. as far as i know it isnt reactive to water, and copper.

bringing this back to life. Does anyone have a link for a US place to buy one? I have googled for an hour and no dice.
Thinking chiller gpu blocks. (blocks as in sli) will 2 of them fit in sli on a Ultra-D ? anyone have 2 on that way?

[eXa]

looks pretty restriktive... ill stick too mcw60.
and lol, that is really awful tubing, i hate those connections

[Radical_53]

The connections are awful, but the block is way less restrictive than it might look. It has large channels and a very solid design.
Restriction is even lower than of competitors such as EK...

Btw., if you get it as GPU-X version with the attached RAM cooling, there's no stainless steel touching the water. All pure copper.

PS: Like it better with some real fittings? :d

[creidiki]

Yeah, the GPU-X is a sexy block.

[andersson.j]

I love the all copper design, it's even nicer than my Fusions!

@ Radical_53: Beautiful picture!

[Clay]

Thx "Ricarus" for pointing it out. Thx "Radical" for the pic with nicer fittings.9The other way looked pretty bad LOL)
Does the ram heat collector thing actually work?

[Radical_53]

Yes, it does work. They all do somehow.

I did a test, like half a year ago. Passive sinks, Alpha aluminium ones, gave me temps of roughly 50°C on a X1800XT fully clocked. All water solutions, if it was aluminium with paste, copper with paste or copper with pads gave me around a 10° drop. Good thing about this design is that the RAM cooling doesn't really restrict flow as it doesn't require longer channels on the block.
