9800GX2 Water Blocks...

*sniff*... male bonding... awww.... so cute...

Here is the production unit, they are shipping out at the middle of next week for those that preordered.

JackUp, does the unit come standard with the top (and maybe bottom) heatsink speaders? (the black ones). Or is that just standard on the GX2? I haven't opened mine so i'm not sure.

Thanks.

jAkUp: Can they be bought for the UK ?

Hmm, it looks that my polished EK WB performs a bit better ... of course with a different WC system though.
It is interesting that EVGA Precision shows exactly the same numbers as it was set in Riva Tuner 2.08, but Riva Tuner hardware monitoring shows different values ... except of the temp.

I have found one interesting thing - we have exactly the same difference in monitored values comparing to settled values in EVGA Precision, for me it looks like the same Riva Tuner with a different skin ... or how to explain such kind of a coincidence?

Is the copper WB better than nickel-plated or there is no difference?

We need an experiment to be sure. For me personally nickel creates another layer between the working cooling surface and a CPU, copper is second after silver regarding thermal conductivity (and is very close to silver at 231 vs 247), though nickel is 4 times less heat conductive at 52.4 only ... but such as a layer of nickel is very thin (it is only 4-10 micron), it shouldn't be a problem.

Then why EK put this nickel, if it make thermal conductivity worse?! If it's only about better appearance, it no sense for me!

Finally I am pretty happy with EK WB, it needs some modifications (spacers) IMO, but the low restriction and temp results worth to use it.

I would like to bring my apologies to Eddy being so inpatient and take my words regarding unprofessional construction back. Well, it just needs to have those spacers, but performance wise (and a look for acrylic version) is above any expectations . Thanks!

P.S. As one can see I have added those copper MC14 mostly for a look, I had to replace the sticking surface (actually it should be called as "non-sticking") by thermal AKASA tape.

Thats what I thought purchasing the copper version ... But the difference may be (and most probably it is) unnoticeable , therefore sometimes it's good to have a choice.

Yes, the unit comes with both the top and bottom heatsinks, also, here are some internal shots

jAkUp: Will we be able to buy them in the UK ? If so, when ?

LOL very creative i like it!

Thats amusing with the E as the pins :P

Nice eye there. I did not even notice that. Clever.

Hi guys: Well now that at least 3 major blocks have been out for a while (DD, EK and EVGA) what is the suggested best performance/value pick? (I was an early adaptor of this card and paid through the nose so I'll be sticking with it for quite a while still so I'm willing to make the WB investment).

Would really appreciate some advice here as my temps on air are just too damn hot under extreme loads and the fan noise is also keeping my neighbors down the street up.

[BlueAqua]

I got the Ek and really like it. You can get it at Performance Pc's for $139 now.



I have it running at 800 core / 2000 shader / 2200 memory and it's idle temps are equal or within a degree of each other at 31C. Load is only a few degrees higher. My ambient temperatures are fairly cool as it's in my basement.

Blueaqua: Damn, that's too good a deal to pass up, went ahead and ordered myself one, thanks for the info. PS: Your setup looks pretty sweet.

[Maxx103]

Blueaqua, I like how you cut out the factory card cover to make room for the waterblock and nozzles, looks like it was made that way from the factory.

Also - slightly off topic and not to thread jack, but how do you like your CPU block?

[Aqua Man]

I'm running two VID-398GX2 on my koolance system and they almost cut temps in half over stock air coolers. Trubritar did a kick arse review of these blocks showing performance buffs as well as cooling temp at load running crisis you should check it out. I LOVE THESE THINGS.
