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.

You're expecting custom-loop results from a closed loop? Okay...

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!!!

That is freaken awesome.

Dude has used that Antec 620 for 2 years and its still working fine.. shouldn't need to worry about warm water destroying the loop. Really, 60-70C doesn't do jack to PVC, versus hard molded plastic in pumps and copper?? Nah wouldn't worry about it.

Just canceled my Gelid 2x order and gonna see if I can set something like this up or wait for this to be released.

While I feel the smaller kits from asetek will work fine - that's what Arctic Cooling is using on their Hybrid cooler, if you want a a system with a larger radiator you can find brand new AMD FX water cooling systems for $60 shipped on ebay......I may get one of these just because it's AMD logo.......

And the argument about hot cooling loops applies as much to CPUs as GPUs. If you feel that it's a valid argument, then don't even look at ANY closed loop cooling kits EVER.....it's an old, contested argument. Closed loop systems have never competed with open loop systems, they compete with air cooling systems, and the same is true here. Sure, you could spend a couple of hundred $$ (or more) on a full open loop system and no doubt would see lower temps.

But, if you can spend $60-$100 and get a silent card that runs at 60C, what's so bad about that?

Yep, I spent $20.- on a 120 size cooler master seidon, $6.- on vrm stick on coolers, and a few cents on some zip ties. Made a 7950 cooler by 20-30c and MUCH quieter.

For a 290x though I would think stepping up to a 240 size rad would be wise.

does this come with VRM sinks and thermal compound?
Click to expand...

No heatsinks nor thermal compound. You can get a set of heatsinks(with removable thermal glue) for $14 here:

http://www.ebay.com/itm/Arctic-Cool...US_Video_Card_GPU_Cooling&hash=item27c718a3af

If you don't have any decent thermal compound around, well, sure you want to be taking a $400+ videocard apart? There is no warranty if you screw it up......this is NOT the same thing as installing a cpu cooler....

It has to be said that this is not a "beginner's" place to go. You will need to adapt any heatsinks you get to fit. If you've never done something like this, or have any doubts about your ability, just wait a few weeks and get one of the non oem cards that are coming.

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.
Click to expand...

same thoghts, i have a palit gtx 770 (non jet stream) that runs really hot
i think i´m gonna get one of these

http://www.caseking.de/shop/catalog...rctic-Accelero-Hybrid-VGA-Kuehler::20849.html

this is my favourite reliable retailer and they have only this
+ its for gpu out of box, should be fine for the gtx770, i know there is a inno 3d version with this exact same cooler

http://www.caseking.de/shop/catalog...lack-Accelero-Hybrid-2048-MB-DDR5::23676.html

the nzxt looks nicer, but one would have to get the basic thing+the bracket and my retailer of trust doesnt have it
performance wise i don´t think there´s gonna be much difference

just saw they have both the kraken and the bracket, but its more expensive, around 130€
have to think abaout it, but i think i´m gonna go arctic

Wow! Much better than I thought. Now somebody do this review while giving the card some voltage :)

[sarcasm]Nothing like a 10 minute run at 69F with a large thermal capacitance to test thermal design[/sarcasm]

Gotta love how that press sample magically only runs at 170w on stock cooler.

Legit Reviews of Kracken G10 installed on a R9 290X. No overclocking, but check out the temps........and there are no heatsinks on the VRMs or memory........

Very impressive. I have a theory on VRM2. This is the first reference HSF that is heat bonded together, prior, the finned heatsink was separate to the heat plate. Now, these R290s run very hot, at that end near the exhaust, thus the heatsink is heating up the plate a lot more hence causing the VRM2 and probably memory modules to run hotter.

As for the amazing difference:

"On the previous page we found that GPU-Z reported a power drop with the water cooler in the VDDC power output reading and that showed to be true at the wall with our Kill-A-Watt power meter. We found that the water cooler helped drop the power consumption by 44 Watts at peak load and they were virtually identical at idle.

44W less at load is a massive difference just for running the card cooler, not to mention this includes the pump and new higher powered fans for the AIO as well. This again verifies other results which show the same thing happening. It really shows how stupid AMD was for going full retard mode letting their GPU run at 95C.

GPUz is not an accurate representation of power load. Add another 50W on top of it.

Hence look at their total system load to see the real figures.

Edit: Its a shame because NZXT have said they all sold out on their first production run of G10s, the next batch wont be available til late January...

Funny this should come up, I'm going to be doing a full jury-rig cooling set up on a 290 very soon. The problem here is that these don't cool the memory VRMs on the left side of the core, which is the one that gets hot. I've got a solution baked up but I won't spill the beans just yet, going to do a full write up with pictures once I've actually done it.

Although in that test it seems like they had no problems without even putting any heatsinks on it, though it was open bench testing... hmmm. The other thing to note is that it seems like the VRMs heat up exponentially faster as you give them more voltage. So no heatsinks might be ok for stock, but c'mon, gonna do all that work to run it at stock? ;)

But I do have one piece of information that should help!

Dude makes his own bracket that's even cheaper than the NZXT one, but it doesnt have the fan slot. Shim is included in the price

Anyone make a 290X/290/79xx bracket compatible with the Corsair H100?
