I have been playing with graphics cards for so long that when I read threads like this I still get an erection, but I have to poor liquid nitrogen on it to sustain it.

Sure sure
It's ok, we all need a lil help every now and then :D

But holy hell these things are screamers. I'd def expect to see a few cherry picks chips hit 1600Mhz+ under water.

Well my lightning can do +400mhz but it does get a lil warm. Interesting to see what the Lightning variants of the 980 can handle.

Yeah, thinking maybe a 2x 980 setup under water could be a nice replacement for my 780s on air. My Swift wants moar frames. Hope to see more benchies of these things water cooled in SLI setups.

That's if Maxwell wont have the same restrictions Nvidia put on Kepler. Lets hope not. Sounds like you had one of the early proper Lightning cards though.

Well i manage to sell my original titans for good money today and just picked 2x eVGA 980's Superclocked basically straight swap with extra $50 on my part.

Even though i got sentimentally attached to Titans after spending $2200 on them was time to let them go after 18months i got $1300 for them not bad for almost 2 years old cards :)

Anyways this new cards are insanely fast rock solid at 1350 OC with 1500mhz boost speed on both cards and mem at 7500mhz for now...
Max temp i saw where 74c on top card and 68 for bottom one with reference cooler i just love this coolers super quite, never liked custom cooling cards with blowing hot air inside the case.

all in all at the new 980's are from min 10% - 35% faster then OC titans at 1125mhz... in all benchmarks i tried around 15 all together.
And they run cooler up to 10c.
Even though i lost 2gb of video ram and Titan e-pen bragging rights im more then happy with new card specifically with rumors of VR-SLi coming, since single titan did not cut it for my Oculus DK2

If you guys need specific 980's SLi OC results you let me know and ill run them...

I'm really hoping Corsair finally put's out the HG10 for the 980 so I can bolt an AIW to my 980, If I can push that thing up to where some of the aftermarket cooled variants are I'll be a happy man.

Got my EVGA GTX 980s which replace the 290X crossfire.

I must say that I can't even hear these things. Rock solid at 1450 Mhz core and 7.4 Ghz memory - all at stock voltages. Didn't try to push further as I was quite satisfied by the performance but I am sure the memory could have gone beyond 7.8Ghz since it's made by Samsung.

On an average I have a 25-30% performance boost over my crossfire setup that was running at 1150 / 5.5Ghz. And 300W less power consumption too.

They're kind of nuts, mines holding over 1500mhz boost and it's a reference card. That's 1.5GHZ on a GPU... still blowing me away.

I guess now I know the feeling to loose all that heat around me during gaming sessions. I got kinda used to it with the 290X crossfire :p

I'm really hoping Corsair releases an AIO cooler that doesn't gurgle constantly and require under-volting to run without buzzing. There's also the fact that many of their AIO coolers CANNOT bleed themselves properly with the pump mounted inverted (like it would be on a graphics card), meaning they literally never stop chewing on air bubbles trapped inside the pump.

I've had to modify both an H55 and an H75 because no amount of RMA's was solving their issues. Quality control for the win...

The HG10 certainly looks like a good idea, but finding a good AIO to bolt to it wont be easy.

I guess your primary aim is to break the 1700 Mhz barrier?

The GPU can do 1550 Mhz on air easily as far as I have observed with mine. But it tends to throttle a bit, dropping down to the mid 1400s during game play. Although my temps never went above 85C. Maybe I need to crank up the voltage and power limits. Hopefully we get a modded BIOS soon so I can try to cross 1600 Mhz on air.

^^^ Amen to that brother. I can't wait to backup and mod my bios and customize it and flash it back. I have high hopes for some amazing results.

My primary aim is to keep the card whisper quiet while also getting a decent OC out of it.

An AIO water cooler would be a great choice for this, but after trying a dozen different ones and ALL of them having some sort of issue... yeah, hard to recommend.

Out of curiosity, what issues were you having?

I used to run watercooling but it was a custom solution (ugly and messy) and went back to air for latest rig because updating the water blocks would've been expensive.

With water cooling my main beef has been not being able to get adequate cooling for memory and MOSFETs on GPUs unless you go for a whole card sized block in which case it is usually useless by the time you switch cards.

Got my 980sc up and running yesterday and pretty easily hit 1504 boost right out the gate. Frigging insane for a GPU. 7710 on the memory. Tried 7800 but it didn't like it so I backed off. No voltage adjustment so I'm pretty happy. Maybe I'll try to squeeze more out of it later but I gotta say I'm pretty happy. Almost frightening to think about what the Ti version is going to bring.

Well, the biggest issue, across the board, was pump noise. Corsair recommends you run the pump on their AIO coolers at 12v at all times, but that's simply too noisy for any PC where silence is of any consideration (louder than the stock Titan cooler at idle, too).

Under-volting the pump to 5v or 7v pretty much fixes the issue, and doesn't impact cooling performance much at all, but it's still a ridiculous problem.

Some pump designs (like the one used on the H75) are also unable to evacuate air from inside the unit when mounted upside-down. Unless you have a case with an inverted motherboard, mounting an AIO cooler to your GPU will result in the pump being upside down, where it can end up with air trapped inside forever. The pump will NEVER stop gurgling, no matter how long you let it run.

Multiple units also arrived hilariously under-filled. Not nearly enough coolant, which also exacerbates the H75's inability to purge itself because there's so much more air in the system. This can also cause the radiator to make tricking sounds because there's enough room for falling water.

I currently have an H55 and an H75 in service (H55 is being used for GPU cooling in my main rig, H75 is begin used as a CPU cooler in a secondary PC). They both had to be opened to add additional coolant, and both of them are running with their pumps under-volted to 5v to eliminate buzzing. I personally recommend the H55 over the H75 for GPU cooling, as it uses a different pump design that doesn't seem to have any problems purging air, even when mounted upside down.

With water cooling my main beef has been not being able to get adequate cooling for memory and MOSFETs on GPUs unless you go for a whole card sized block in which case it is usually useless by the time you switch cards.
I resolved that by using the front-plate from an EVGA ACX cooler on my GTX 780. It covers all the RAM chips and VRMs. I then thermal-epoxied RAM-sinks to the plate over the hotter components. The G10's 92mm fan seems to keep things cool enough when combined with the front-plate. The back-side of the card's PCB doesn't break 90c while benchmarking, according to an IR thermometer.

Here's what the card looks like. This was right before I removed the permanently-gurgling H75 and replaced with with a (personally repaired) H55. Cooling performance of the H55 and H75 appears to be identical in my installation. Makes sense, since they both use the same size radiator and I used the same fan on both coolers. Only difference is the pump design.

Both fans (The 120mm fan on the radiator and the 92mm fan on the bracket) are wired together and plugged into a single motherboard fan header so Speedfan can control them. They run 600 RPM at idle and ramp up to a maximum of 1450 RPM if the GPU core goes past 60c (this is rare).
You can use the fan header on the graphics card + EVGA Precision for speed control if you prefer, but you'll need to use PWM fans if you want to go that route.

^ Nice cardporn, Unknown. I've been a disciple of the AIO cooler + bracket (dwood, the one that started it all) scheme ever since stumbling on this miracle with my GTX570. The performance-per-dollar on this investment has been absurd - paid $35 for an Antec 620 and $7 for the bracket and I've been able to re-use it on every single card since (570 -> 680 -> 780 -> and on Monday, a 970). Have been able to always run the cards overclocked to the hilt, and temps always within 50-60C at full load, always easily destroying the performance of the factory air cooler. And best of all, its pretty much silent.

I used to be all about custom loops and getting that extra 2-3C cooler but convenience is king these days, and the AIO method gets you "close enough" to custom performance without all the headaches of custom -- like draining and filling the loop every time you want to change a component, or the recurring expense of a new custom waterblock every time a new card comes out, or getting 10 cents on the dollar in resale when replacing that waterblock again. Good riddance.
