watercooling 6950 dirt3

So my understanding is because of non ref cards I need to use universal block for the GPU and then some tiny heatsink for VRAM modules?

Yes that is true but make sure that the universal block you get will actually fit your model GPU because not all do even though they are "universal."

yes the card in question is on supported list, would my VRM get wery hot with those tiny heatsinks?

what about other parts of the card that are not covered by a full block?

 Not sure about the heatsinks but they are the best you can do without a full cover block. You only need to cool the VRMs and the actual GPU the other parts of the card don't get hot.

Thanks that makes sense, do I need airflow to the cards?

I'm also considering getting a ref 7970 and full cover EK block, I think then Airflow to cards is not necessary as the EK cools down core + VRM.

If you aren't using a full cover block and just using heatsinks air flow over the card will help keep it cooler, no need for the extra air flow if you are using a full cover block though.

Well the Cpu cooler is a Mugen so it won't be blowing any air at the graphic cards, so even with a full cover for 7970 I still might need to have a fron, side or bottom fan aimed towards the GPU's.

You don't need any extra air flow with a full cover block the water passing through the block will carry all the heat away into the rad and then the fans will blow it out of your case.

The extra air flow is only needed if you are using a universal block and heatsinks on the VRMs to help blow the heat away from the VRMs. The GPU will be cooled by the block so that wont need any air flow it's just to help cool the VRMs.

Do the 8 memory modules need heatsinks?

Unless I misunderstand the important is the VRM to left of core?

According this image VRM already has heatsink from stock?

 

[SieB]

  You need heatsinks on the memory modules they are VRMs (Video RAM Modules)  the heat sink on the left is not very good either get a better one.  

 

[ruthless_villain]

VRMs are voltage regulator modules arent they?

 

[SieB]

I thought it was the video ram :\

Edit: Yes I was wrong VRAMs is the memory , you do still need to cool both though

If I get Zalman for memory and keep the orginal Sapphire VRM, can I get away with just the Haf 932 200mm door fan running wery low 500rpm for low noise system?
