Looks good, but it's rather irritating that no other blocks other than the hydrocoppers cover the entire pcb. I understand it cuts down costs, but charge more for the item so it doesn't look so bad comparatively. Ek, Koolance and Aquacomputer all do this. Sadly DD is the closest to fully covering, but the blocks are just meh.

I agree with the others that its a very nice looking block, but its a shame its on such an ugly card. tongue.gif

I feel this way too, although its not necessary it is nice to see blocks that are symmetrical with the PCB. Its nice to see blocks coming out for something we can't even get our hands on yet though, shows that it will be a hot seller when it finally hits the stores.

meh, that's my last concern. Already 150lbs, what's another 4-5oz each? Not like anyone watercools to save on weight anyway.

First real test:

Loop:
EK-FC7970 prototype block
360 RAD
3x Yate Loons D12SL
2m 12mm ID tubing (1/2")
D5 Vario + EK X-TOP V2
EK-RES X2 250 Advanced
EK-12mm High Flow fittings

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

furmark.jpg

Furmark ran for almost five hours!
Cards running at stock volts yield the following results:
Tgpumax = 41°C
Th2omax = 30.7°C
---
dTmax = 10.3°C = ~ 10°C

Overclocking the card to 1125/1500MHz (GPU/RAM respectively) @ 1.250V yields:
Tgpumax = 42°C
Th2omax = 31.1°C
---
dTmax = 9.9°C = ~ 10°C

The dT does not increase not even at these circumstances. Cooling engine holds fine! smile.gif
Also the VRMs are noticably colder than we are used to. The hottest measured temperature was ~ 49°C (behind the MOSFETs, back side of the PCB), highest logged temperature was 50°C after 5 hours of Furmark.

The best thing about the block - flow rate. It surpases our flagship CPU waterblock EK-Supreme HF by a large margin. You can easily run four of these cards out of one mediocre pump! :up:
Attached is the hydraulic curve for EK-FC7970:

Serial production - block in the making. Made in Slovenia - Europe:

Hi both,

@tsm106: I believe the adequate stock should be available for purchase from EK webshop by the end of next week, perhaps few days earlier. Retailers will have the our water blocks some 5-7 days later.

@just_nuke_em: I was testing only the FC waterblock.

Regards,
Niko
