EVGA preps water cooled GeForce 7950GX2

[Darksaber]

EVGA is playing around with a GeForce 7950GX2 with water cooling. Innovatek is providing the cooling, with hand made water blocks. The setup keeps incredibly cool, even when overclocked. The usual 7950GX2 temperatures are hover just under 90 degrees celsius. The EVGA card barely hits the 50 degree mark. The GPUs can be overclocked to around 600MHz, while the memory reaches 1500MHz without breaking a sweat. Do not expect the card to be cheap, as the hand made water blocks will surely raise the price by quite a lot. Expect a street price of 750-899€s.

sucks
-aluminum = corrosion
-1/4" connectors = no flow

there are other people working on a 7950GX2 watercooling solution that won't suck.

Aluminum doesnt really = corrosion. I have aluminum in my loop and havent had any issues. 1/4 isnt that great, but anything bigger wont really fit through the cards. Looking good.

mixing metals is a bad idea 100% of the time. it will always decrease performance and there are always risks associated with it for absolutely no good reason. Sure, you can mix in all the addative crap you want to to "prevent corrosion", but thats just reducing your cooling power by diluting the water. aluminum corrodes when mixed with copper, its a fact. the process can be slowed and so on, but it still happens. it requires maintenance. good waterblocks with delrin, copper, brass, acrylic, or anything that isn't aluminum tops don't. also, this block will most likely be entirely aluminum, and for what purpose? copper is more efficient for a base material, there's no doubt about that, and as a top material copper (or brass or what have you) is a better choice than aluminum too. also, 1/4" fittings are not mandatory; larger fittings can easily be achieved even with such a thin space. a 1/2" connector flattened down a bit fits in between the cards, providing the same height as the 1/4" connector but the same flow cross-section as a 1/2" one. then, outside the cards in the spacious emptiness, the "flattened" connector can be rounded out to a 1/2" barb.

absolutely no logical reason for aluminum or puny connectors to be present, and yet they are.

We really shouldn't fight over video cards we can't afford anyways . The point is that the cards stay below 50*C. Did anyone else notice the advertising ploy on the box? EVGA is calling these cards "the black pearl"...might get some girls into computers lol.

Wait... you want EVGA to flatten hoses so they can fit bigger ones in? :S Thats just asking for a kink... BTW all you need to do to prevent corrosion is put in a chunk of zinc in your res. It will corrode instead of the alluminum. It should leave you corrosion free for years.

 

[XooM]

no, not hoses, just like take a round copper tube with a 1/2" diameter and flatten one end of it out a bit. 1/2" round on one end, 1/4" by 1" oval on the other (made up dimensions of oval)

A GX2 with proper cooling???!!! Running decent clocks???!!!


They may be on to something here....

-_-

 

[markkleb]

Did anyone notice the "90 C temp" of the reg card, What a POS, LOL

 

[demonbrawn]

No kiddin.
