Kepler arrives, so does the EK-FC680 GTX series water block

[tiborrr]

The demand is again crazy high. We have blocks manufactured and assembled daily. Don't worry, yours will probably ship tommorrow at latest.

EDIT: We've made an installation video for EK-FC680 GTX:

haha, im quoting you in 2 different places now.

the tap vs distilled water was actually just debunked by martin a few days ago. the distilled gets contaminated in just a matter of days and so it makes little difference. also i change out the water every 6 months or so, and clean out my cpu block (the pins make a great filter).

it's not about contamination. but galvanic corrosion with tap water coz it contains ionic minerals when contact with copper based wb. distilled water is mineral free.

time to ask martin about this, since i have no idea about these kinds of things.

Ya, it's more about the minerals in tap water that you don't want. Especially if you live in a hard-water area.

yeah the more i read the more i think i should spend the 1-2$ on some distilled. and i do have hard water problems in my house.

Ah, no worries. Not a huge deal Just looking forward to filling out my loop with the two 680s. I would of probably paid more in duties/taxes shipping to Canada from frozen in the US anyways. In the past I've almost always lucked out and not had to pay duties on international shipments coming to me via DHL.

Got my EK blocks! Thanks a lot Tiborr for your support!
Temperature are wonderfull 42°c after three hours of gaming, quality is very good and assembly is easier than 7970. But i'm a little disappointed one of my cards is not as good as the other...

Yeah, I wouldn't recommend tap. While I have it in a loop for over a year now without problems, tap is different for every area and grocery store distilled is less than a dollar and well worth it's purity level for the low cost. I just question the value of double distilled and ultra pure waters that cost $10-$20 a liter. Regular grocery store or any water purified with a distilling process is good enough in my book.

Anyhow back in topic..these new cards and blocks look really nice. I like the bare copper version myself.

so has anyone got theirs up and running and can show us what their results are?

mine got miss-sent from frozencpu, so it wont be here until tomorrow

No problem buddy, glad to help out a friendly customer. As for the overclocking goes: yeah, one of my cards is also a dud - only ~ 1280MHz stable on the GPU, Vgpu tweaking still not working. That's why I prefer Radeon

[penguins]

uhhhg, All the 680's are out of stock!! I've never seen a gpu get bought up this quickly before. I see like 3 on amazon for 600 something dollars.

edit; ah looks like galaxy and pny replaced some of their cards

I hear ya. I have both my blocks but haven't been able to get cards yet.

[penguins]

there is a galaxy at newegg.... but Do I want a galaxy ? I'm somewhat partial to asus...

I am sorry for such a novice question, but am a bit uncertain on the instructions. It says to apply additional TIM to the "Phase regulators". Where are these? EK has posted a video installation guide, but this step is omitted. I have searched all over Google and found nothing. Thanks for any help

Not necessary. Just use thermal pads and tim on chip.

[squick3n]

New problem. I have a Gigabyte card. One of the standoffs doesn't line up. Its obstructed by the PCB. It's not in a critical area, but it's still concerning. I used my phone for the camera so apologies on that. This is the best I can do until the cable company gets out to fix the Internet.

[tiborrr]

Very interesting indeed as this is P2002 PCB, nVidia reference design. Care to share P/N number of the graphics card.

I don't know if you can tell from the picture, but if I had an M3x10 I could thread it down to the copper. It looks like the intended standoff is touching the layer of thermal pad placed over the coils

[tiborrr]

Very interesting indeed. I know it sounds stupid but have you installed the block correctly. I would suggest loosing all the screws and repositioning the water block. Then start screwing in the screws on the far edges of the water block. Also make sure you've put the thermal pad where you should, trim excess that overhangs the coil.

Thanks for cooperation!

P.S.: The standoff's thread is M4, the inner thread is M3.

[squick3n]

Uploaded those from having just taken it apart. I don't see how I could have put it on wrong if all the thermal contacts are in the right place

[tiborrr]

Woow!

The standoff should be in this hole:



Use some pliers and place it in correct spot.

Can you please provide QC check number (not the one that was inside the mounting mechanism bag but the one inside the cardboard box)?

Regards,
Niko

I thought it didn't look right, but this is my first ever WC build, so I'm pretty much following directions. As I noted above, there was a bit of disconnect between the included instructions and the Youtube video guide

[tiborrr]

Thank you, squick3n.

Proceed with standoff repositioning and reinstallation. If you encounter any more issues please contact support@ekwb.com

apparently these don't work with the evga backplate (http://www.overclock.net/t/1240214/g...evga-backplate)
