Considering going down this route. How are the Vrm's being cooled on this 290X?

http://www.overclockers.co.uk/showproduct.php?prodid=WC-069-TL

Or is the NZXT KRAKEN G10 GPU Cooling Adapter sufficient enough to do this job on it's own?

Any info on this chaps?

looks like the 92mm fans cools the VRMs.

Looks tasty, think I have an old Corsair cooler around somewhere. Have to see if its compatible.

To you perhaps. To others out there, they may prefer the NZXT. I know I do. It looks clean and rather tasty, whereas the Arctic one looks a bit plasticy and weird with all the angles. Not bashing it, I'm sure it's great. But, how do you know it provides better cooling? Just out of curiosity...

Tis personal preference though when design comes into play

The Kraken you supply uses the same pump and radiator as the Hybrid so temps should be close to each other.

VRAM and VRM temps have the chance to be a lot cooler on the Hybrid.

Looks promising cheers.

What about some deals on this and some compatible coolers Gibbo?

rjk · 21 Dec 2013 at 18:18

this isnt gibbos thread?

there will probably be some bundle deals when the stock lands.

See this same avatar thing screws up stuff to people

I do.

EK Water Blocks EK-VGA Supreme HF Copper Shim @ £3.95 inc VAT

A 0.5mm thick copper plate adapter which fills the height gap between the AMD Radeon HD 7970 / 7950 series GPU and the surrounding metal shim.

This use of this copper adapter is mandatory in order for EK-VGA Supreme HF series water block to make proper contact with the AMD Radeon HD 7970 / 7950 series GPU. Also useful for installation of extreme cooling solutions (e.g. liquid nitrogen evaporators).

Notes: Please use thermal grease on both sides of the adapter plate (not included - we recommend Arctic Cooling MX-4)

Technical data:
- Dimensions: 28.5 x 28.5 x 0.5 mm
- Material: Copper
- Application: Radeon HD 7970 / 7950 GPU
- Mounting: Clamp force between GPU and water block

Only £3.95 inc VAT.

ORDER NOW

Any idea when these are due in?

The Accelero cooler looks to be a complete PITA to install, also the VRM and RAM heatsinks need to be glued on making this upgrade pretty much a one way street. This in itself would rule it out for me as I'd always be looking to put back on the stock cooler for a future sale. Cooling isn't the only factor into getting one of these things.

I've glued heat sinks to the last 5 cards I've used the Hybrid on and I've not had a single issue.

As long as you use the right amount the heat sinks will remove easily and be very easy to clean up.

Failing that thermal tape is also an option that many people use.

And you have to run some form of VRM cooling on the Kraken anyway so it's a moot point to be honest.

It's quite easy to install also

Geeman1979 · 30 Dec 2013 at 13:26

This is what i'd like clearing up. Is the cooling fan sufficient enough to cool the Vrm's or are separate heat sinks actually needed in conjunction with the Kraken.

still waiting for the stock currently. I have asked EK now to see if there is an update.

Andygully · 30 Dec 2013 at 13:58

looking forward to getting the kraken and was thinking about the shim for my 7950.
Do you guys have compatible heat sinks for the vrms that fit under the fan? also the tape to attach them

On my overclocked 7970 ( 1.25v @ 1150Mhz ) my VRM's can hit 60c under load.

That's with the hybrid fan on auto controlled by the graphics card and a VRM heat sink.

Geeman1979 · 30 Dec 2013 at 16:29

So what are deemed as acceptable temps of the Vrm's, say on a 290X?

Check my thread history and you'll see I reviewed a hybrid on a 290, complete with VRM results.

That was a with a massive heat sink on the VRM's, that heat sink could not be used on the Kraken as there's not enough clearance.

VRM temps put me off the Kraken that's why I ordered the Arctic hybrid instead (and now ocuk is out of stock) although I preferred the look of the Kraken. That video review linked further up the page is terrible there's no mention of temperatures just the fact the card doesn't throttle anymore (which we would assume so as the card won't be running up to 94c).

Agreed!

I also prefer the look of the Kraken.

The legit review link has VRM temps in it. Here is what it says..
http://www.legitreviews.com/nzxt-kr...oler-review-on-an-amd-radeon-r9-290x_130344/4

The NZXT Kraken G10 is not a full coverage water block, so that means the GDDR5 memory and the VRM components are no longer dissipating heat to the reference cards heatsink. In the past we have found this to be a major issue as some parts of the card can overheat and actually run hotter than before. The NZXT Kraken G10 helps combat this by having a 92mm fan on the custom designed bracket to help keep the PCB components nice and cool. GPU-Z reads the temperatures of two areas of the VRM. We aren’t sure what two VRM areas GPU-Z is reading though. We asked AMD PR and they thought that VRM1 is most likely VDDC (the 3D core power rail) and VRM1 is most likely VDDCI (the MC power rail). VRM 1 was a bit warmer on water when at idle, but once the GPU was under load it was actually cooler. During the benchmark run the air cooled card averaged 63.9C and the water cooled card averaged 62.2C at VRM 1.

VRM Temperature 2 showed a huge decrease in temperature with the NZXT Kraken G10 + Kraken X40 water cooling combination. The Sapphire Radeon R9 290X retail card with the AMD reference cooler averaged 78.4C and the NZXT water cooled setup averaged just 51.3C!

Almighty said above that his hybrid cooler hits 60C on the VRM, I reckon they are pretty comparable for the VRMs then. I'd still go with the Kraken if I was to get any.
