nice look jdrom17...I like the EK blocks...I also have the Klipsch Pro Media 5.1 setup..."tight" hahaha

The ''Borg Cube''.

Still some wire management, and unwrapping (the top!) lol, to do, but it's fully fonctionnal. The 5970 is not a big card! Look how small it is!

2 loops, 3 Triple Rads. Tri-Crossfire: 5970 + 5870 with EK waterblocks. Mountain Mods Extended Ascension.

Do you run those 5770's passive? In Xfire I don't see fans fitting.

You are right as there is no room fans on either card, I have two 120mm fans built into my case that move a lot of air through them.

I did the following mods on the cards:

I got rid of the plastic junk attached to the cooler to start:



And then lapped the surface of the inside cooler, this is not an easy cooler to lap. I then cut the coolers down by around 1cm in order to fit nicely into MacBane, I took my time with a pair of shears and got some pretty good results. I sanded the cut end of the fins (not shown) to get rid of any sharp edges or potential metal splinters or fragments.





I cut the VRM sinks to size and started putting both cards together.





Something important to point out: If you use the stock spacers that come with the cooler there will be a 1-2mm gap between the cooler's base and the GPU die as seen in the image below.



This will likely give you a bricked card if you try to run it like this, so I made some smaller spacers out of PVC tubing and was good to go (Stock on the left, homemade on the right).



As for temps I have stupidly great results . With an ambient temperature of 21°C my Crossfire load temps have gone from 100°C down to 51-54°C, and the idle temps have gone from 65°C to a very friendly 31-33°C. And I eliminated two 80mm fans worth of noise and energy usage in this mod, I am damn happy with this setup now

Great mod! I've heard about major crossfire heat problems and this look like a good way of fixing it.

any chance of sticking this as a guide in the how to section???
