Does EK have GTX280 and HD4870 FC blocks coming soon ?

[Repliquant67]

This is with the EK block and RAM block combo for the GTX280?

Yes. I have to wait now the return of the rma to test more.

I screwed in cross first the screw near the gpu and check two time the print on the thermal grease and try at first with barbs on the ram block and in second time one on the ram block and one on the vga block. In every case, in burn I was over 100°C. I checked alos the inside of the vga block : everything alright. My vga loop work well. Now I have only 52°C on furmark (1680x1024 aax16) with the 8800gtx at 675/1530/1060 with the ek fc8800gtx sli block.

Edit 3 : I think this is because I have only two metal o-ring with hole and I need one without for the junction between the two blocks. The liquid don't spread properly and pass more by the ram block who's less restrictiv.

Sorry, I don't understand what you're saying. Please provide pictures if you can. Did you install barbs at each "end" of the water channel on the waterblock? Or accidentally installed at the same "end" of the water channel, on opposite sides of the block?

If so, that would explain your temps....

[Yozzman]

frozencpu has em too



hehe yes, i spent 8 hours friday night cleaning every single part i could get with a Qtip and then rebuilding everything.

the hardest part was figuring out how to fill this new loop with a T-line. had never used one before. i finally came to the notion of opening the tline top, as well as the thermochill fill bolt on the top of the rad, and then slowly filling the system until coolant topped out of the rad have to have the radiator sitting with the fittings end on the bottom, and you also need to have the tline tube longer than the height of the rad. i should have taken a pic of that >< sorry. anyway, yay for atmospheric pressure!

Any temp readings?
VRM etc?!?

Repliquant67: I think you have mount this:



But i want know that can look like this with ram block for gtx280 from EK:
Because i think that is impossible on Rampage. But i can be wrong ofcourse.

[jagt]

eddy any word on a 4870x2 waterblock?

Bumping this question.

No, I mount the waterblock and not on rampage but on a maximus formual. I gave the pictures one or two page before of the block (pictures from Eddy)

I remember in another thread some issues people were having with watercooling the 4870. Does the EK block cover all the necessary chips properly? IIRC there was more than just the mosfets that needed cooled.

Well, I tell you, the aquacomputer one seems to cover those areas much better.
With my EK I found the solution to be, well, not as solid as the aquacomputer.
Also, the thermal pads they supplied are insufficient (the amount provided).
You see, the part you have to screw to the main block is the part that cools those Chips, and they supply thermal pad to apply between that and the chips, and that part doesn't really touch the small ones so I had to cut the thermal pad in 2 or 3 pieces and stack them on top of each other to make sure theres contact.

So, my card runs cool, and no game has crashed (I actually play games lol)
And be damn carefull screwing the EK to the card... the PCB bends really easily

[skinnee]

yeah...pretty sure I'm going with the DD Tieton on this round, the EK seems to be heavy, problematic and overpriced.

For the probleme, it is maybe only for my waterblocks or maybe I did something wrong when I mount ...
I can't give my opinion because I did'nt test completly

This is the same with the fcr600 : http://www.ekwaterblocks.com/downloa...stallation.pdf
Picture at the end of the first page, o-ring are surounded...
But maybe I'm wrong and the probleme com from somethingelse

Edit : Eddy wrotte me that he will produce full spacer (like for the fcr600) in order to have the two blocks in serie and not in parallel. I hope it will work fine with mine because otherwise the blocks are very nice.

Asus rampage formula and asus maximus formula - that is the same mobo
I saw this pictures but i ask about picture with mounted block on card which is put on mobo

[Repliquant67]

A gtx280 with the EK FC280gtxback and the EK FC280GTX sli fit without problem with an asus maximus formula.

[JaD]

It might just be me, but I find it silly having a 50 bucks ram-block on the back, but no water flowing over the PWM in front

The main purpose of a full cover block should be to cool adequately every single component, but right now any production block is just using copper (if not aluminium) plates on power circuitry. We all know how much heat PWMs produce, and it's more than RAM's. Not a single wb maker is even putting fins over there... again, silly.

Interesting question. I always wondered why the wet area was just around the gpu chip and a large portion of the cards components were not "under water". I assume a decision is made how much cooling the components besides the gpu chip need, and probably a cost issue. Though most FC block have alot more surface area "under water" than say a chip only block and a unisink like the DTek. I can't claim to be an expert in either cooling or block design, but would love to hear input form those that know more about this and could explain the decision better.

That's a very valid point. PWMs don't seem to get the same attention, maybe they should? Having said that, they generally can tolerate higher operating tempereatures than other sensetive components; up to 125degC on the 4870.

Any news ?

[Repliquant67]

No. I'm waiting a new gtx280. If I don't receive one, I will wait the gt200b I think. My problem come maybe from the fact that I thigt the screws around the gpu before the one that attach the two blocks together (manual was released after I received my blocks). Maybe ....

Vga block is around 700 gr and ram block 500 gr. For the people who was worried about the weight.

[Malik]

I will soon order this ek blocks for my gtx. When all will come i take photos

[Repliquant67]

Ok. I should not have the new card before 2 weeks I think. I'm waiting your results.

[GazC]

I should have my EK block and Ram plate for my GTX280 tomorrow. I'll let you know how things go.

Yes I found the same thing. Used a bit of (lapped) copper sheet 18SWG (0.048") fixed on the VRM with thin thermal pad and MX2 on the top of the copper which makes very good contact with the aluminium block.
Here are the results with q6600@3.4Gz + 2 x 4870s in Xfire+ NB block+ mosfet block all on the same loop with a TFC 480. Running OCCT and rthdirbl

Room temperature 25.1 degC

[GazC]

I mounted the block with the RAM backplate today on my GTX 280. The results are terrible, I've tried mounting twice and the temps go sky high in 3D straight away. I'm going to try mounting one more time before I stick the aircooler back on.

I wish I had shares in a thermal paste company

[GazC]

Great. Now my card is broken. What a crock of s.hit.

Do You speak about the aluminium back plate or the ram waterblock.
Sorry for your card. Welcome to the club ...

[Malik]

Finally i have my gtx


My old one and new one gtx

Now waiting for ek blocks

[LogAn'sRun]

Now that these blocks have been on the market for a while, has there been any verdict on which one performs better? I just picked up a 280gtx and want to replace it with someone's full cover block. . . . but which one??
