Hi all,
My CPU is water cooled (Corsair Hydro H80i) and I have a very silent PSU (Cooler Master Silent Pro M2 1000W).

But the 2 AMD Radeon 7870 XT GPU's (linked with Crossfire) are making quite some noise and sometimes they get too warm and the PC freezes up.

My PC is not used for gaming but has another purpose. Both GPUs are running 24/7 at 97% to 99% activity. I have not overclocked them.

The GPUs make quite some noise after a few hours and I want to reduce this sound. Possibly by using liquid cooling.
I am looking at the "ARCTIC Accelero Hybrid Extreme VGA Cooler-nVidia/AMD, Liquid/Air Combo Ultimate Cooling". Do you guys think this is a good choice for a dual GPU set-up??

Any ideas for this?

Let me know!

Thanks in advance.

If you were gonna liquid cool them , then go for a proper custom water cooling loop, a single 360 rad will easily cool 2 gpu's like that
I'm guessing your bit coin mining or something to that effect to keep the GPU's up with such load constantly
 
Theirs not much point adding aftermarket coolers to GPU's unless your going all out and custom water-cooling them. That's what I suggest you do, any other solution wont really solve the problem or will raise their own (such as, where are you going to mount three separate 120mm rads?)

Thanks for the answers, I appreciate it. I am indeed using it for Litecoin mining (For Bitcoin I would need MUCH faster system).

I think I will order 2 of these bad boys: http://www.overclockers.co.uk/showproduct.php?prodid=WC-059-OE&groupid=2180&catid=2183 to replace the current stock 7870.

My MOBO is the Asus Sabertooth 99FX R2.0 and it has 4 x PCIe ports, do you guys think that 4 of those custom cards (see link above) will fit? As they do not seem to have fans, they look a lot slimmer on the picture.
 
You could just buy the cards and mount water-blocks yourself, but anyway.

If you have the slots and appropriate spacing, then there's no reason you couldn't have four of them. However practically no, you couldn't.
The motherboard only has the slot bandwidth to run 3 cards without running into issues.

Are you aware of what a custom water-cooling loop entails?
