4870 Waterblock Options

[Tsaroth]

As snipe said, all heatsinks need air over them to remove the heat. Otherwise they are passive and those chips on the 4870 can't do with just passive cooling.

Every case out there should have some sort of airflow, even if you're running WC you are going to need airflow to move the hot air out of the deadspots that are in your computer (I think there are typically 2 areas where warm/hot air accumulates inside a tower case).

Now does the fan have to be right on top of iandh's kits? That is the question.

I thought those kits had problems cooling the VRMs unless they had a fan blowing or something... it was brought up before I think.

all heatsinks need fans to blow on them.....

Hi!

If I may add, the new version of Aquacomputer block offers different PCB cooling solution than EK-FC4870 GS.
So there are 3 different PCB's that are currently supported by water blocks.

[Stoner133]

I have two of those koolance waterblocks for my pair of 4870's, nice waterblocks have yet to see the temp rise above 40c with them.

[PCFlip]

I am in this same boat, I have two ASUS 4870 1gb with the dark knight heatsink and well I want to water cool them and for the most part from what Im hearing the Full coverage water block is a better solution?

This is what I have come down to as my options;


* EK-FC4870 CF - Nickel
* Koolance 4870 full coverage block
* XSPC Razor 4870
* Danger Den DD-4870 Full Cover Waterblock
* Swiftech MCW60-4870 Full Cover Waterblock
* D-Tek FuZion GFX 2 if they had a unisink I would use it but it appear not at least not yet so what about using the stock cooler in its place similar to what others have done already on here. (I would have to buy a stock cooler as well the dark knight heatsink is not a ref. cooler ~_~ )

So Im interested in hearing from people that has used these blocks and what their thoughts are as well as performance results? I have been spinning my head in circles about this. Well thank you for any advice, suggestions, and help you can offer.

Edit: Nevermind guys, I have a friend selling me his EK 4870 block for 68shipped so all I will need is a second and well thats a pretty good deal so ya Im going to jump on that.

Now does the fan have to be right on top of iandh's kits? That is the question.

The sinks have to have airflow over them, yes. The fan most definitely does not need to be directly on the card; but the flow must be laminar (fresh air moving linearly over the card).

I acheived ~80-90C VRM temps with moderate OC when using Accelero S1 with Yate Loon SL fan (approx. 50CFM). That is very reasonable IMO.

These are hot cards. Sink size has little to do with it... you either need good airflow, or an FC block. You could put gigantic sinks on the VRM's and if you don't remove the heat with good air circulation, the VRM's would still get hot enough to cook eggs.

Larger sinks do allow for better cooling ability with less airflow, but I do not like large sinks hanging off of my cards, and I find direct/semi-direct cooling with a single low speed 120mm fan to be a very reasonable requirement for my smaller sinks.

If you are going to be v-modding/heavy OC'ing, you need to go with a FC block, period.

That said, I have run my sinks on three seperate 4870 512mb's and on 4870 1Gb with low speed fans, and as of yet have had no overheating problems whatsoever...

Can anyone point me to the manufacturer of this, second version of the card 4870? I was searching allot and just cant find it

Looks like Asus (maybe, hard to tell under the heatsink) and Diamond make these versions with the analogue PWM:

Looks identical to the PCB of the the Diamond card to me.

@Eddy
The shown card "Typ 2" is a Club3D 4870 OC-version. You will not find it on the website of Club3D (nor in the shops, they are all showing old pics of old layout), the layout has changed in the meantime. But I have it (1 GB version, bought 01.12.2008) and I know it for sure. The layout is the same for 512 MB- and 1 GB-version. Aquacomputer uses these cards for their "ready-to-go-cards".
What is more, Powercolor changed their layout of the PCS+-version, too. It looks the same now (with analog mosfets):

I put a Aquacomputer Aquagratix Typ 2 on my card - seems to be the one and only fullblock-solution for this layout at the moment:

Thanks, this is good info.

@Eddy
Will you also produce a block for this layout?

This is the naked Club3D OC 1 GB:

[WaterFlex]

We will also have a new variant ready to the end of the next week:



Both copper blocks are connected via a Delrin bridge so the voltage regulators are also watercooled
The block will cost 79,90 EUR.

Which exactly HD 4870 videocard I should buy? It`s quite hard to understand it...

It´s not only hard to understand, it´s just gambling. I ordered this one
http://www.club3d.nl/index.php/produ...phics/item/357 but was quite certain (after some investigation) to get the above pictured one. And I got it

Hi!

Yes I am constructing the ALU part for this block. It should be ready in 10 days max.

[WaterFlex]

Will this card fit on Aquacomputer Aquagratix Typ 2?

[scamps]

Have a look at post #235, first link. Actually the PCS+ seems to have this layout, too.

There is also old revision of PCS + layouts. They don`t fit to new aqua wb.

[Eddy_EK]

Hi!

As SCAMPS wrote, this powercolor card might be TYPE 2.
So You better check the real PCB version.

[WaterFlex]

Hoooooh. It`s impossible to find out it
So guys. ax4870 1gbd5-pph is ok?

Hi all
I am looking for a full cover block for my 4870.
I have read this thread from start to finish today . This is my first time here and this forum looks really helpfull
I have a sapphire card with a blue pcb. Again with a new analogue vrm set up. I think I am right in saying there is nothing out there to cool this card fc wise.
It looks like it would be very similar to the aquagratiX typ 2, but i think a little different. I got a relative to buy me a dangerden fc block for my b-day b4 i had the card, and of course it ain't gonna fit.
The thing with the dd block is that i could cut the end off the block, from the end of the memory cooling. Then just try to cool the vrm's with something else. Or i will just stick it on e-bay
The mounting holes are looking the same to me around the gpu.
Do these analogue vrm's keep a bit cooler than the digi ones, I read earlier ppl having all sorts of trouble cooling the digi ones. I could whip the card and and post pics of under the sink if it would help.
Anyone shed some liight on this for me?

Yes, I have seen that also.
We will also make the ALU part, that will fit to the Sapphire blue pcb card. We should have it ready in 2 weeks.

[TexT]

Thats great news eddy.
And thanks for the quick response!
Can you tell me where I could watch and where to get it as soon as its ready

[STi489]

Is there a single block setup to run 2 4870's or do i need to buy 2 blocks and add extra plumbing?

[TexT]

Sti I am no expert in all matters. But i think you will find to run two cards you will always require 2 waterblocks. The only way around it is to run the 4870 X2
