Specs:
Gigabyte 990FXA UD3
AMD FX 8150
2 x Gigabyte GTX 560Ti SOC (This is not a reference card)

Planning to build a custom loop my budget is $1000 (all in - including tubes, blocks, fittings etc.), my case is a Corsair 600T and Im pretty sure my only option is to mount my rad externally.
 
Triple rad on top of case for CPU, triple on solid side behind mobo for video card loop. Just an idea.
 
To remain internal: Look into a 200 mm rad for the front and a 240 rad for the top. you can also squeeze in a 120 on the back. I did this, minus the 200 mm in my old 600t. Worked really well.
 
A 2x120 and a 1x120 should be more than sufficient to cool your system. You'll probably spend ~$500-700, depending on how much value you place on aesthetics.
 
We need to know more about your intentions...do you want to overclock? Do you care about noise? That will effect the rad surface area you need, and ultimately where you can put your rads.
 
I dont really mind putting the rads outside and I will really overclock the 8150. Im not really concerned about the noise but i don't want something like a vacuum cleaner :p

I would like to put water blocks on the CPU and the 2 video cards and maybe the board NB/mosfets if my budget fits.

Forget the NB/mosfets blocks, and put your budget into a larger radiator.

Larger radiator = better cooling with less noise.

Since you're fine with an external setup, for the price of most fullcover NB/mosfet blocks + radiator, you can get something like the Mo-Ra Pro 3 120mm version. And you will have truly epic cooling with near silence. 1200 RPM fans should suffice, and they would be nearly completely quiet.

For that setup your going to want fat rads. Im a huge proponent of the XSPS RX series. I have an RX480 running a 2500k at 5.0ghz with a 6950 2gb at 1.0ghz with very acceptable temps, with 1000ish RPM fans, and good pump/res. Very quiet and powerful. Seems like a single RX480 or comparable rad combination will do what your lookin for given you have 2 GPUs.

Acceptable temps!?!? I should say so! That's a lot of rad for not a lot of hardware! But it wouldn't be [H]ard otherwise. ;)

If you want stay internal thick rads are out of the question. There is no room above the mobo or on the rear of the case for big rads. I had the RS240 on top and the XT120 on the rear. I had to mount the fan for the XT120 on the outside of the case. And the RS240 barely cleared the ram and 8pin mobo power plug. Honestly the 600T isn't the greatest WC case. Not without modding. But an external 360 or 480 would be just dandy.

Personally not a fan of XSPC radiators due to their extremely low FPI making them not good with fans above 1000 RPM in push/pull.

Sorry but...no. Might want to take a look at this.

Most radiators perform pretty similarly. Even at 2800rpms, the high FPI BlackIce GTX only beats the XSPS by 1.5 degrees on an SLI system. At 1400rpm and below, the XSPC beats it, with much lower fin density and therefore less noise. Basically, the XSPC is so good that it doesnt need push pull, which is entirely over-rated in the first place.

Acceptable temps at those clock speeds and low fan speed makes it really not that much rad, quiet was a must, and i also wanted lots of overclocking headroom.

That doesn't show push/pull, it's a pull only setup (or push, whatever they used).

http://www.overclock.net/water-cooling/518786-huge-radiators-roundup.html

The RX480 gets overtaken by the GTS 420 at around 700 RPM in push/pull. The TFC Monsta (very low FPI like the RX, and also a 420 design) gets overtaken at 900 RPM.

How can you directly compare a 120mm fan rad to 140mm fan rads?.140mm flow more air at the same rpm. You would have to raise the fan speeds of the 120mm to match the volume of air per surface area to get an accurate comparison of what the radiators heat exchange abilities are. How can you say with any confidence that the difference is due to the FPI? Theres more to a radiator than FPI...

Either way, the point of a low FPI radiator is to use sub 1000rpms fans...

Actually, the opposite is true. And I gave you a direct 140-140 comparison inside that also.

140mm fans may have more airflow, that is true, but they have lower static pressure, which makes them worse on high FPI radiators. So a XSPC 480 (which has more surface area than a GTS 420) with 8 120mm fans loses to a GTS 420 with 6 140mm fans starting at 700 RPM.

And if you look at the TFC Monsta compared with the GTS 420, you can see it loses to the 420 at 900 RPM. Both are 420 radiators, so they're using the same fans. One is ultra low FPI (around 8 like XSPC radiators, and thick as hell, like RX radiators), one is ultra high FPI (32). So given the choice, since the GTS radiator in push/pull can fit in the same space as the TFC Monsta in pull only, the GTS will perform better.
 
Great discussion guys, one more question:

If I ever decide an external rad box - what is the best way to power the fans? use an external AC adapter or connect a long extension from my PSU ? will a 750w PSU handle 9 of these and 3 case fans?
 
The fans you linked to use max 13.5v*.19A=2.57 W per fan. So times 10 to give you some headroom 25.7 watts, and as for the case fan I'd say 5 watts per max. All in all you need less then 70 watts for sure. TLDR: Pick up a cheap PSU you don't need 750 watts.

I have a 750watt on my rig its running 2 x GTX 560 Ti and a couple of HDDs, If I run a 4pin molex extension, Will it handle those fans and a pump?
 
Once you get something together Onin let us know how the temps are. I'm really curious to see how the new BD FX8150 does out in the wild OC'd (as you said that's what you were intending, right?). Reviews tended to think that the power draw ramps up pretty quick, so depending on how high you take it, it'll be interesting to see.

Also, while I can in no way state this conclusively, if the power draw really is what they're talking about, I offhand might be concerned about a 750W psu handling an OC'd fx8150, 2 560's (presumably oc'd too?), and the rest, especially depending on the quality of that psu.

I will definitely post it. I have a Corsair TX750 V2 and Yes I have factory oc'd 560s Im gonna have to use universal blocks for it and stick some heatsinks since they aren't reference cards.

Easily, especially if you have a good power supply.
 
Just an update, my budget wont make for an external radbox but I will most likely will do it in a few weeks.

What I ordered :

Watercool HTF4 w/ 3x noise blocker p3s
Aquacomputer Cuplex Kryos
D5 pump
FrozenQ res with D5 mount
2 x EK VGA Supreme HF Universal + Swiftech Universal SLI bridge + Ramsinks
Bunch of bitspower compression fittings (worth almost $200 :mad:)

and some odds and ends

Thanks for the replies.
