I have a custom water loop to cool my 3930k and 2 GTX670FTWs. You NEED adequate radiator capacity. I have 2 360 rads (XSPC RX360 and XSPC EX360) to cool the cpu and gpus. Since the R9 290X has large thermal output, especially OC'd, I would consider adding another rad if I ran 2 R9 290X gpus in CF. My present rad system wouldn't be overkill for a single R9 290X. I have full block gpu coolers. The memory really needs them for OCing.
You could, but it won't perform well enough to OC crap. It will not dissipate enough heat. You're better off on air.
Not a single link in what you posted includes a GPU heatsink. And I can tell you, that shit hackjob 480 doesn't cool a thing.Wait let me link you again:

You don't need barbs if you don't want to, cable ties do just fine, you don't even need a res. you can also go all the way Magaiver and just get a H80 and do this:
You might know how to watercool, doesn't mean you know everything about it, watercooling is a concept not something set in stone, where there's a will there is a way, stop being arrogant...
PS: The card in the pictures is a 480 and has a TDP of 275w....
Why would you risk a $550 vdeo card with such a cooling scheme?
But..but...but I can put a universal heatsink on the chip and attach it to a garbage pump and a 120mm radiator!

The OP was about max OC and I can tell you that card isn't running some cheez duct tape it together trash set up.
This is expected with this kind of chip. It appears the 290X is high leakage - it will respond to voltage and clock well as long as you keep it cool.I was looking for watercooled 290x's to see how well it would overclock and came across this reddit post you might enjoy
here is the 3dmark score
it gets around 15k in the graphics score stock speed uber mode, but almost 19k here
he says it doesn't go above 50C overclocked under full load,
maybe this is the titan killer we wanted
To get this thread back on track:

That GPU only block will only get you so far... I had one on one of my 7970 Lightnings a while back, and it did well, but required active cooling on the VRM/VRAM plate. Had to rig up a fan to blow directly on it. It worked, but meh.
My loop arrives tomorrow

You can do a cpu kit like I did, RS120 for $130, then a GPU block for $100, sell the cpu block for ~$45.
But you wouldn't want to run a cooker like the R290X overclocked on such a small rad with a cpu in it.
This is the highest core clock I've seen so far for the R290X on water, needs to go higher or it just looks like a waste of money vs on air 780s.

firstly R9 290X is significantly faster clock for clock compared to the GTX 780. R9 290X at a 1125 - 1150 mhz easily matches or exceeds a GTX 780 at 1300 - 1325 mhz . its only the golden classy 780 at 1400 - 1450 mhz which requires a 1250 mhz R9 290X to match.
btw your GTX 780 is getting whipped around in the biggest PC title this holiday season especially at 1440p / 160p which is where these cards are required. with Mantle its going to get ugly for Nvidia. :biggrin:

whats this a Nvidia TWIMTBP title running better on R9 290X :whiste:

According to hw.fr the 1GHz R290X is 9% faster at 1440 than the 980MHz GTX 780. R290X just needs to go higher, there is no other way to put it. 1250 on water for a setup that will cost much more than non reference 500-570 dollar GTX 780s that can hit 1300-1400MHz all day isn't going to cut it :|
Because BF4 Single Player is what everyone cares about, right?
Ouch.
Better get that Mantle going because they clearly aren't doing something right, like supporting DX11 features?

No, you can't. 290X waterblock is $150. CPU block is another $85. I've broken your budget without a pump, res, tubing, fans or rads.
Every PC I have had in the past 5+ years has been watercooled. It is not a cheap hobby.
Seeing how CPU bottlenecked that test was, one could imagine something went wrong with the testing. 32 players vs 64? Changed map? It looks like it have very little to do with graphics card and more with CPU.
I guess the only difference there would be the $1000 processor driving the system vs the $220 or less in the other? Maybe different OS (8.1 with your link)?
Either way even the downtrodden Titan is right there at lower clocks so I'm not sure where you are getting the idea that Nvidia needs vastly more clock speed to beat the 1GHz R290X when none of it's cards are hitting that in stock configurations?
I'd rule cpu out since they use the same cpus for both cards at various speeds.
The other factors at play are the 1K$ chip swe used, perhaps driver difference, or OS (not sure what the other used, but this one used 8.1)
None of this of course takes away from the fact that at 980MHz the GTX 780 is within 8% of the 1000-990MHz R290X. Which doesn't allow the idea that Nvidia needs huge clock speed differences with their less costly GTX 780 that also offers non reference currently to beat the R290X. Certaininly doesn't change the idea that 1250 for the R290X on custom water is a poor investment vs $530 top end GTX 780s.
I could do it for under $250 ..from scratch..with cpu included..and have lower temps than your loop.
