D-14 On GPU?

[iNothing]

The Kraken G10 is great and attaching a closed looped CPU water cooler cools the GPU alot, but i've been wondering has anyone ever attached a Noctua D-14 onto a GPU?

[MegaDave91]

That would be the weirdest thing I've ever seen if it were even possible.

[Excon]

No.... It would break the card in half and it wouldn't fit right into the motherboard, you would need a riser cable.

[Oshino Shinobu]

I hope not. Besides, you'd need to use a riser card/cable and probably a lot of modding.

I don't think that would be possible, it would put enormous strain on the GPU, as the cooler would be sideways with all that weight. It also really wouldn't fit, unless you had a riser card even then I still wouldn't do it. 

[iNothing]

Yeah, I thought so

 

I was just thinking what it would look like and how it would run

 

I think it would be an achievement if someone did it

[TheSLSAMG]

...

 

The card would obliterate itself. Not to mention the PCI-E slot.

 

 

Oh mother of god.

[WoodenMarker]

I doubt it. It'd be overkill though. Gpus don't output nearly as much heat as the cpu. 

[MegaDave91]

Yeah, I thought so

It would look like an NHD14 sitting on top of a graphics card, and would run no different than being on a CPU. It would do an excellent job though.

Oh mother of god.

That's a painful sight.

[Hans Christian | Teri]

Wouldn't surprise me if someone has done it, I mean as long as you take the right precautions it should be completely possible. It will take some stabilizing in order to not kill both the card and the socket though.

[GameHard6]

I would love to see it in action though it wouldn't work well.

[ivhyn]

Oh boy, that VRM would be really hot

[applebook]

Wrong. 

[lachyman]

Wrong.

He's right, they don't output a lot of heat, that they eat a lot more is a different story.

A mid-range GPU requires far more power than a mid-range CPU, e.g. 4670K vs 770 Ti. I know that TDP doesn't translate precisely to heat output, but how is it possible for a CPU that draws 84 watts to generate more heat than a GPU that's taking in 230 W?

Gpus have larger dies and manufacturing process. Also, the TDP stated is for the entire graphics card including all the things on it and not just the gpu. There are parts on a graphics card that generate heat that aren't the gpu.

I understand that, but how much power can the caps, regulators, and memory on a mid-range GPU really draw? Most of the 230 W has to be for the graphics core. 

[Face2Face]

Mid to high-end GPU's put out much more heat and consume much more wattage then CPU's do = Wattage = heat  

[applebook]

Mid to high-end GPU's put out much more heat and consume much more wattage then CPU's do = Wattage = heat  

 

From what I've read, there is much disagreement about this, but most people agree that the more power something draws, the more heat it tends to output. I'm unsure there is a perfect method for finding this out, but I can tell you that from class A audio amp experience, the more watts = ridiculous heat!

Not sure.

They don't. Something like a 780 runs at ~40c at load with a Kraken x40. The same can't be done for the cpu. http://www.nzxt.com/product/detail/138-kraken-g10-gpu-bracket.html

Let's look at the actual area for heat dissipation.. CPU vs. GPU

 

Using the Intel 3570K die as example and the Nvidia GK110 (Kepler) die for comparison.

 

Intel 3570K total die size - 160mm^2 

 

 

As you can see 33% of which is iGPU. Around 50% is actual cpu cores, so let's say 80mm^2 of actual area for heat dissipation.

 

Now let's look at Kepler -GK110

 

Total die size 551mm^2

 

 

 

 

 

Let's take a look inside - about 75% of the chip is made up of SMX clusters - Cuda cores which create the heat. So let's say a little over 400mm^2 of surface area for comparison.

 

 

on a 3570K you have the bare die - TIM - IHS - TIM - AIO cooler -  80mm^2 area to cool

on a GK110 you the bare die - TIM - AIO cooler- 400mm^2 area to cool

 

Not only do you have a smaller area to cool, but it's harder to cool because of all of he material between it and the AIO cooler.

 

Here is the base of an AIO cooler (H55) Don't know the actual size in mm for comparison, but it's rather large. Perfect size for a big GPU like the GK110 or Hawaii.

 

 

Do you think it would be easier to cool a smaller concentrated area of heat or a large more spread out one with the above?

 

 

Do you think a 3570K that runs at 80c at stock frequencies using 77w outputs more heat

 

                                 VS.

 

a GTX 780 running at 70c at stock frequencies using 220w?

 

 

Do you understand what I am getting at?

This is still speculation though considering gpus run cooler with the same cooling solution and there aren't other results that show gpus putting out more heat.

Speculation?  Did you read anything I posted?

 

Heat output is measured in watts. More wattage consumed more heat generated - Enthusiast gpu's consume more wattage therefore output more heat vs. CPU's.

Simple concept.

If I put a 100 watt light bulb next to your face, you will feel the heat generated by it. If I put a 250 watt light bulb next to your face, you are going to be uncomfortable..

 

If you you are referring to the Linus on the Kraken G10 video, he is just plain wrong. It's okay though, he has been wrong before and will be wrong again.

What you posted was speculation. You didn't post any results of actual measured heat output.

Not all the power used is turned into heat. 

How is he plain wrong? Results from just about everyone including the Kraken G10's results on the website show a gtx 780 at 40c at load. You won't see the same result for a cpu.
