I've been considering going with water lately to keep my rig cooler, and most importantly, get it as quiet as possible. I'll admit i'm a little out of the loop (ha ha) when it comes to water cooling. I'll be selling some more of my old parts soon and would like to put that money towards setting up a water loop.

My specs are: i7 860 @ 4.0Ghz / HT off Gigabyte P55-UD6 GTX 470 @ 750/1850 4GB Mushkin Redlines @ 1528 / 6-7-6-17

My temps are already decent now, i'm hitting around 70C under Prime on the CPU, and around 70-75C on my 470. The only problem is, my rig sounds like its ready for take off with the push-pull setup fans on my Venomous X and case fans all going. Its kind of funny, the 470s fans are actually the quietest in my rig. I would also like to be able to OC my i7 a little higher or even just be able to turn HT back on. I can't run with HT @ 4.0 or my steps start shooting up to 80C+ fast.

This kit was recommended by Kow in another thread: XSPC Rasa 750 RS240 Universal CPU Water Cooling Kit Hot Item! - FrozenCPU.com

Now, what would i have to add to that kit besides a GPU block for my 470? What blocks are good for the 470 without breaking the bank? I assume the rad in that kit would need replaced for something bigger, but would everything else be good to go with a GPU added? I might not be adding the 470 at all since its fans are fairly quiet and it doesn't get too hot, and i need a new case first, but i would like to know just for reference. Would it be better to setup a custom loop instead of buying a kit like that and adding too it? If so, any recommendations?

I'm not sure how much i'm looking to spend yet until i sell some stuff, but i would like to get a general idea of how much money i would be looking at for a good setup.

Buying that kit and adding another 2x120 rad or 3x120 rad wouldn't be a bad idea if you want a cpu/ gpu loop. Not sure if that pump is strong enough for two rads and two blocks though.

You might want to build a custom loop if you dont mind waiting to find deals.

SwifTech has an interesting modular GPU HS/WB design that accommodates among others the 470. Lowest price I've seen on the HS and MCW60 block is around $85 total for the two. Might be able to find it cheaper somewhere. The MCW80 is superior in heat transfer, but higher priced.

If you were to add your 470 to that loop, you'd need some more hose, and depending on the block, barbs(1) and clamps(2). That's it.

I wouldn't recommend doing this however. Even with an RX240, that'd be pushing it, so an RS doesn't really have a hope. See how much it would cost to get the same components seperately, but replace the RS240 with an RX360 or PA120.3 from Thermochill (they're very similar.)

(1) Barbs are what screw into the waterblocks, hose is then attached at the other side. Usually G1/4 for the thread size, and 1/2, 3/8, or 1/4 inch for tube inner diameter. (2) Clamps simply hold the hose in place when attached to the barb. You can also use compression fittings, which arguabely have a better seal, but you're not going to need that kind of hold unless you're hooking your loop up to and industrial pump or something. They do look a lot nicer though.

The 240 rad in that kit is enough for just the cpu. If your going to add a gpu block then you will need to ditch the 240 and buy a 360 and a extra fan. The pump will do the job (just) at 750 lt/per hour although you should look for a pump closer to 900. It it was me I would ignore that kit although for a single cpu it is a great kit and go custom. If you have space for a 360 rad then chances are that is at the top of your case so there is still space for a 120 rad were the rear fan goes. As you already looking to buy a gpu block and a extra rad then buying a 360 and a 120 rad with a pump, cpu block and resevoir is not going to be much more expensive.

That pump is far too weak for two blocks and two rads, which is what you'll need to add your video card. Presumably, it's sufficient for one rad and the CPU or this kit wouldn't exist.

A single 240 is enough for a CPU, or a GPU. Not both. A 360 should be able to handle the heatload well enough, as will a pair of 240s in series. (In practice, most users will never see simultaneous full load on CPU and GPU. If you do run applications that result in this, however, a 360 and then some might be a good idea, depending on how much heat you're generating.)

The problem you're going to face is that a decent pump or rad, alone, will cost you almost what that kit does. Think about that for a second, and reflect on the relative quality of components at work.

Also, most modern video blocks are of full cover design and will set you back around $120. This is, I assume, primarily because of the ridiculous amount of heat that video VRMs are putting out now. They're prettier than core-onle blocks, at least...

And a thought on tubing: I run 7/16" ID Primoflex over 1/2" Fat Boy barbs. No clamps needed and there is no difference in ∆T over 1/2" ID tubing. I bring this up because it looks at lot better than clamps (and frankly, works better) while avoiding the fitting issues that compression fittings can cause with a lot of blocks.

Aqua Computer Aquastream XT Ultra USB 12v Pump | Ebuyer.com This will be my next purchase. It controls the fans and it is listed as usb device in windows so it can be controlled :)

The thing I don't like about the idea of running a CPU and GPU on a 360 rad is that only one of them gets freshly cooled water.

Question though? I'll call this the "Rad Rad". Would it make sense to make a 360 rad with 4 fittings, each pair with pipes on only one half of the rad. The water from one block would go through the first half of the rad, to the other block, then through the other half of the rad, all with one pump.

Seems to me besides making more efficient use of space and money, having one block at a time send warmed water through the rad would also allow that half of the rad to have the effect of a larger than 180 cooling area, due to the rad fins being part of a larger unit, helping to dissipate the heat more than each half's own surface area. Ideally it might have the effect of a 240 surface area for each block, vs 180. The only thing is, with the extra tubing and fittings, would it put too much strain on the pump?

Theres no such thing as cooled water, its a loop. The water in the loop is all pretty much the same temperature. Maybe a 1* difference after passing through the rad but thats about it.

If that were true, the block wouldn't actually be taking heat off the processor via water and sending to the rad to be cooled. From my understanding the whole point of WC is that water more effectively removes heat from the processor than air. Obviously the water then gets warm at the contact point of the block, otherwise the rads wouldn't be necessary.

In the case of two blocks on one rad, you have even more wattage to account for in the loop as far as removing heat from the processors plural.
