I think I'm just going to stick with a 360 30FPI rad and a MCP655 to power my sli and CPU and go from there. Thinking serial res>pump>CPU>GPU1>GPU2>rad.

Yikes......that's one screaming build.  3000 RPM Rad fans?  That radiator might be possible for 2 GPUs with high screaming fans on it.  You're underraded to add the 2 GPUs and CPU on it.  You're going to get temps as if you were on hot air.

My goal is low temps 1400MHz OC. Would I be better advised to get 2 240 rads with maybe 20FPI? Will one pump suffice? This is getting complicated...

JerkMan... this isn't complicated at all :)
 
A single D5 ( also known as the MCP655 ) pump will be all you need for your rig no problem.
 
Rads... just figure a 240 for each GPU and a 240 for your CPU. That equals 720 so you could go with:
1) -- 2 360's or 420's
2) -- 1 480 (or 560) and a 240 (or 280)
 
I will be building my rig in the next few weeks when I get time and will post pic's then as well. Hope this helped and just remember to have Fun with this bud :)
 
Your Rad FPI will depend on what kind of fans you want to go with. Slow or fast which comes down to noisy or quiet. I will be running my feser rads which have 12 FPI because they will cool great with low RPM Fans.
 
*** crezno above also makes a Good Point on FPI and that will also determine size and number of rads. I like to have my rigs Quiet so I choose less FPI with slower fans but I will also need bigger rads to cool my parts vs higher FPI and noisier fans. Also comes down to how much space you have in your case.

+1  I am in the same boat.  Like quiet, silent operations at full load (magical).  I go with SR-1s for radiators and Helix120 PWM fans.  Can't wait to upgrade my rig in a few days.

What are your opinions on 120's? My case is running out of room and only have room for a 120 on the back; already have a 360 on top.

Crezno are you hitting 1397 on stock LN2 bios and voltage?

.  Added in my TEC unit, and some passive heatsinks to the backplate and I hit well over 1500. Need to wait for my second half of the heatsinks to get in to try it in sli.

 
Can you post some pics of how you installed the heatsinks to the backplate?

Hi,
 
Just got a classy this weekend. Barely been home though so haven't really got the time to play around with it. I have high hopes for this card :)

Do u have any information on when more cards will be in Europe? :)

Hi guys
 
Im new  here and i have a question about EVBot.Can i connect it to my gigabyte g1 sniper 5?and how can i get a higher voltage with out changing the bios?as i would like to get some more juice from my classified
 
thanks for help

Pretty sure EVbot only works with Evga products, would make sense lol.
 
You can do 1.35 through software using the aftermarket tool, but you will hit the power target limit way before you get there.

Thanx,witch softwere is best to use?is there any chance to unlock AB?
Witch bios should i use? And is there a guide how to do it?

Im realy thank ful for help

Is this program alowing me to change the bios permanent?with out flashing it?

For some reason i can not save my bios using gpuZ :(

You clicked on the icon on the right-hand side next to BIOS version?

Can't really figure out my card and the classy overvolting tool. Best bench I was able to pass was at 1293Mhz (1306Mhz passed, but with some artefacts) with 175+ on the mem, although i haven't tried any higher with the mem really. However, wasn't game stable.

Voltage is also a bit odd. Adding 0.038 via Precision seems to increase stability, however it never goes higher than 1.125. Once, when I just pushed the card to boost out at 1320Mhz it hit 1.1320 (or something similar) before crashing.

Now, the classy overvolt software... I was told you should adjust the sliders, shut off the computer and then boot up again. However, whenever I'm back in Windows again all the settings have reset to default. What am I missing here?

Not really sure if the overvolting is really interesting since my card seems to run very hot. Even at the fans running at 100% it couldn't keep my card below 79 degrees at 1280Mhz which until that point (about 45mins of playing) seemed like game stable. 

Only way to know what voltage you are really pushing is to use the headers on the video card and a voltmeter.  EVGA sells a probe-it connector to make it easier.  The software stops being accurate on the voltage once you start adding more voltage that normal software will get you.  And also, typically these cards pull more voltage than you set when its at full load. 
 
79C at 1.35v full fans even at 1300Mhz is pretty normal. Temps probably wont change much if you kept that voltage and raised it to 1400Mhz.
 
Seems like the average max overclock for these cards is right around the 1400Mhz mark with 1.3v+  I can say from exerience, you should not aim to push past that amount even with a BIOS unlock for 200% power target, if you are not running L2N or some other kind of solution to drop your temps to freezing levels, even at 1.5v there is not much stability to be had without extremely low temps.
 
With waterblocks and 40C full load, Max stable OC i could reach was about 1446. Didnt seem to change if voltage was 1.3 or 1.5  I ran my TEC unit in the loop and i hit 1500Mhz no problem. Just a little insight.

Yes ,i have the latest version of gpuZ 0.7.2 and im presing the button on the right to the bios version and im getting that. "BIOS reading not supported on this device"

Any sugestions ?

Thanx
