First glimpse at the EK-FC7970

[tiborrr]

@wolvers: No, sorry, but I believe it can shave a degree or two off the VRM.

[wolvers69]

OK, thanks. I guess it's more of an aesthetic thing then?

[Bestofbritish96]

Yes, the back-plates make a massive difference visually. Some Tri-7970 EK love:

You have a kink in the tubing :p

My system with the copper/acrylic EK 7970 block, lovin' the looks under black lights

[lowfat]

Looks good with milk.

[tiborrr]

Brilliant, lowfat!

nice

is there going to be a two slot adapter plate for this

Yes, the back-plates make a massive difference visually. Some Tri-7970 EK love:

Oh damn, that's nearly the exact same setup I'm going to start in the next few days

Your photos are actually quite useful to me in determining dimensions since the only thing that has arrived so far is the case. Glad to see someone else with a similar build and quality photos

I want to see the FC-7950 block :p (I actually want it, but I'm already talking to Gregor about that )

[JohnMike]

Also the work is nearing completion with FC waterblock for ASUS HD7970 DCII:

Why isn't any EK-VGA Supreme HF Bridge Edition available for the DCII ?!

[tiborrr]

It is, should work like a charm.

[JohnMike]

It is, should work like a charm.

But the EK Cooling Configurator doesn't show that option like it does on the reference gpu card.

Regarding ram & vrm cooling on the Direct CU II, looking at this photo from EK CC site... Is the EK-VGA Supreme HF enough for cooling the Direct CU II sence ram & vrm seems already taken care by reference cooling PCB plate?!


Regards

[tiborrr]

Edit: My bad, just physically checked - capacitor and inductor are in the way. Sorry, no Bridge Edition possible.

Also, very proud to show you this (you have probably seen it already):

any more on the EK-FC7970 DCII water block because it looks like it needs more cooling going by some [H] posts

[aReado]

I got some problem with my newly purchase wb, plz advise
http://www.xtremesystems.org/forums/...like-corrosive

[tiborrr]

@aReado: This appears not to be exactly new - it looks used. The screws could corrode if they were exposed to water since they aren't made of stainless steel.

I present you the EK-FC7950 water block validation sample. Already done hydraulic testing as well as some thermals, will post results tomorrow!



The block should be available for purchase in 2-3 weeks and should cost the same as EK-FC7970 series. It will be available in all four versions (copper plexi, copper acetal, EN Nickel plexi, EN Nickel acetal). FC Backplate coming as well!

Sweet Jesus that's good

2-3 weeks?

[Raul-7]

Why do all the new blocks have this nickel plate on the top? Why not all-acetal or all-acrylic like previous blocks?

[Waterlogged]

Why do all the new blocks have this nickel plate on the top? Why not all-acetal or all-acrylic like previous blocks?

...because the water needs to jump over some caps or other non cooled components and the only way to do that is to machine the top side of the block.

We have completed internal testing of our newest EK-FC7950 water block, built specificaly for the AMD Radeon HD 7950 graphics cards based of AMD 109-C38137-00 PCB. Once again we have managed to manufacture the highest performance (both hydraulic and thermal wise) water cooling product.

The test has been conducted using the following water cooling components and measuring equipment:

- EK-FC7950 prototype (RTM) water block
- EK-RAD CoolStream XT 360
- 3x Yate Loon D12SH-12 120mm 2200rpm fans
- 2m 12mm ID tubing (1/2" ID)
- D5 Vario water pump + EK-D5 X-TOP V2
- EK-RES X2 Multioption 250 Advanced
- EK-12mm High Flow fittings

Measuring equipment:
- Greisinger GTH 175/Pt J-type thermometer, calibrated
- Voltcraft IR-800 20D IR thermometer
- Digmessa digital flow meter FKHU series

Furmark torture benchmark which stresses the graphics card to the maximum was ran for more than one hour. Graphics card Radeon HD 7950, running at factory set frequencies and voltage yielded the following results:

Tgpumax = 37°C
Th2omax = 29.8°C
---
dTmax = 7.2°C = ~ 7°C



Overclocking the graphics card from factory set 830/1250MHz to 1000/1375MHz (GPU/RAM respectively) - note that we were not able to raise Vgpu voltage via software therefore it remaind at factory set 1.090V - yielded similiar result:

Tgpumax = 38°C
Th2omax = 29.9°C
---
dTmax = 8.1°C = ~ 8°C

Where Tgpumax is the highest temperature of the GPU core, logged by software; Th2omax is the highest temperature of the coolant measured by thermometer; dTmax is the highest delta (difference) between the GPU core temperature and the coolant temperature - lower is better.

Please note that the smallest resolution for Tgpu probe is 1°C therefore a rounding error is present. Considering this fact we can see that dT does not increase more than a 1°C even at overclocked conditions. The VRM (voltage regulation module) also remains cool, the hottest measured temperature was ~ 45°C (behind the MOSFETs, on the back side of the PCB).





The EK-FC7950 water block's hydraulic curve resembles much the one of EK-FC7970. The design once again features extremely low flow resistance, again even lower than the CPU waterblock EK-Supreme HF. As a result any medium performance water pump will run four of these water blocks yet still offer enough flow for optimal system operation. Picture below shows the hydraulic curve:



The EK-FC7950 water block - which will come in all four versions (Copper Plexi, Copper Acetal, EN Nickel Plexi, EN Nickel Acetal) - is already listed in the EK webshop and will be available for purchase on March 13th 2012. The matching FC Backplate is also in the works and will be available in the following weeks.

any news on the EK-FC7970 DCII block

[The Jesus]

Can't wait for these 7950 blocks

[Rattle]

Can we use just the back plates on reference 7970? I'm not water cooling but I want a back plate.
