new bracket for GPU liquid cooling

[monkeydelmagico]

NZXT has a new bracket for closed loop GPU liquid cooling:

Looks similar to a home made dwood bracket from overclock.net. It's cheap at $30.- Not alot of compatability info available from the website yet but it's nice to see a major manufacturer stepping in to help us use these cpu coolers on gpu's.

Is there anything for the Vram?

 

[KingFatty]

The 92mm white fan is for blowing air over the VRAM and other stuff, and the liquid cooling thing is mounted on the GPU itself.

I wonder what this would do to a R9 290?

 

[smithkt]

I wonder if these brackets could be used with blocks for custom loops rather than the AIO kits? Could this be an alternative to full cover blocks?

Looks pretty good for VRM cooling.

Does anyone make a 200mm asetek AIO cooler that's like this?

I don't want to go custom water.

That looks like a great product for NZXT cases.

I don't see why it wouldn't, if the AIO fit in the hole around the GPU.

That would be good for custom boards that you can't get F/C blocks for. :thumbsup:

I'd love to see someone test one of these to see what kind of temps you'd get on the vrm and memory chips. Looks like you would need some passive sinks as well. Might make the cost of setting up a loop more attractive knowing you might not need to replace full cover blocks every time.

I just ordered one of these for my new R9 290. I have used dwood's version on both a GTX680 and a HD7970. He's gone now, missed greatly. You need to get some heatsinks for the memory chips and the VRM,s( check ebay for the AC 002 kit - about $13). Both the GTX680 and the HD7970 are still running fine - and silently with great overclocks: GTX is 1200/1650 and 7970 is 1150/1500. Neither card runs past 65C - most games the cards rarely see 55C......and, again, they are silent.

I have been reluctant to get a R9 because I couldn't get anoher bracket...this was great news for me.

I wouldn't put a 290/290x under water without at least 140x2 or 200mm backing it up.

140 x 140 x 2 = 39200 sq mm
200 x 200 = 40000 sq mm

So it makes sense that they market this to be for their Kraken asetek AIO.

How did you verify fitment? I couldn't find any compatibility specs yet.

If it's not too much trouble, it would be great if you could report back with your impressions of this thing once you have it installed.

The compatibility chart is on the web page.

Whoa they changed the website alot since yesterday. Thx

Bummer. Cooler master seidon is not one of the compatable coolers.

Aye,im guessing you will still need passive sinks.

None of the coolers that aren't sourced from Asetek will be compatible.

For me this is something like this would make me consider water cooling for my gpu for the first time. Something simple, much cheaper, and hopefully able to be reused for future cards. I am looking forward to some reviews to see if it works well.

For those who feel a low end AIO will not cool a R9 290:

https://www.youtube.com/watch?v=D44pXi9Cjkg

FYI final stats: 1170@ stock voltage
38C idle 51C load
Installation with Zip ties...very ugly, worth the cost of the mount for the looks......AND.... It's SILENT!!!

Be more than happy to....

Those aren't very impressive heat numbers for a watercooled GPU though, its not uncommon to get them down into the low 40's C with a good waterloop. This is what watercoolers call a hot loop. A hot loop has water that exceeds 10 C over the ambient temperature, while GPUs with their large silicon area don't seem to have a temperature much above the water (hence a hot loop still cools them very well) a CPU has a temperature far in excess of the water temperature.

GPU hot loops are a good way to save on radiators, so long as you don't put them in the same loop as a CPU (this guy didn't). My estimate would be the water is somewhere around +25C, which is likely accelerating damage to the pump and the tubing greatly, but it'll work for a while before the heat slowly but surely destroys the parts.

It also won't actually keep at that temperature under actual high loads for very long. What the small radiator closed loop people are doing is basically the exact same thing AMD/ATi is doing with their reference blower. Have enough mass to absorb the heat but not enough radiator to continuously dissipate it.

Typically I would put 2 120mm radiators for a GPU at 800rpm (the thick kind). The radiator they have there is good only for about 90W of dissipation at 10C water delta, so for a 270W card its going to be near +30C just for the water. Of course they tend to run these things a lot higher than silent, somewhere around 1500-1800rpm typically and that puts the dissipation more around 150W, so it really is skimming +20C or so. I doubt it gets much hotter than that at any point, its capable of cooling the card, not as well as a custom loop but as a hot loop it will do the job.

On that note, just ordered one of these.

It's the highest performing asetek 120mm I could find. I hope it arrives with all the pieces there since it's open box. Will order NZXT bracket once I verify.
