Liquid cool GTX 690 in quad sli

post #1 of 3
Thread Starter 
I have two GTX 690's in quad sli, aside from the fact that I can't OC them over 100mhz, they run hot. 90c hot, and they run loud. I want to try to get these two on liquid although I have never done anything liquid cooled short of my corsair CPU block. I tried to determine what I'll need but there is just so much information so much customization there's nothing really ready to go that you don't have to build yourself. Can someone give me a jump on what components I need? what brands? etc etc? I know I need a water block, pump, radiator, and reservoir but have no idea what to do from there. Any help would be much obliged


Thanks in advanced!

- Find out what your case can handle in terms of radiator

- Figure out how much total cooling you need. Do this by looking up the wattage used by the components you want to cool in power consumption reviews. For instance, a GTX 690 has been measured to have about 270 watts at full load.

- Decide what speed of fans you're comfortable with. This greatly changes how much radiator you will need.

- Use some measured data to figure out how much radiator you will need for your fan speed and your heat dump. For example, using the data from Martin's website (http://martinsliquidlab.org/2012/04/12/alphacool-nexxxos-ut60-360-radiator/4/); a UT60 360 will dissipate about 215 watts with fans at 1400 rpm to maintain an air/water temp delta of 10C. That means using one 360 per GPU at that fan speed would yield a bit higher air/water delta (maybe 12C-14C).

- If you need more radiator than your case can hold, then you'll need to look into an external radiator or decide not to overclock your CPU much due to a much higher air/water delta.

Best way for us to help ya buddy, is to list the specs of you rig. We can't do much without knowing what ya got and how much radiator space your rig has. thumb.gif

I'll throw out a couple links on what you'll need to cool your two GPU's though:

GTX 690 Waterblock
Radiator
Swiftech MCP655 (other versions available)
Reservoir
Tubing
Compression Fittings
Or
Barbs

Make sure when choosing your tubing and barbs/compression fittings that the ID & OD match.
