how much space do you have in your case for a radiator pump and res? if you dont then you will need to look at an external unit. Or external RAD and internal pump and res. The external unit can either hang on the back or go on top, like mine -
Then cooling power which is usually measured in watts. 700W cooling system is plenty for 1 CPU and 1 6990.
Once you've decided on the unit, then grab the tubing and coolant depending on your tastes. most blocks are G 1/4 BSP threaded, and then the nozzles/connectors are matched from there to the tubing. As a guide Koolances G1/4BSP threading, 3/8" ID nozzles and 1/2" Tubing all go together.
The blocks are easy, Id go Koolance the 6990 block worked well, can say much about the 6970 but thats another story. In fact I think the culprit was my PCI slot.
I know the case has enough space for a res + pump. I'm pretty sure you can put a 240 at the top inside w/o any mods, but a 360 is out of the question internally in the HAF922 without mods. Here is one completely internal HAF922 setup cooling an i7, but it doesn't look like there is any WC on the GTX275:
A guy on another forum runs his HAF922 like this, but he never mentioned his gpu/cpu specs but it certainly isn't a 6990 for the gpu:
I really don't care if I have to mount a large rad externally. You mentioned a 700W cooling system is enough for a cpu and a 6990. What kind of rad/fans cool 700W? I looked at a forum that had some heat dissipation comparisons, but I wasn't really sure what they meant.
Here are some of the suggestions I've received about the HAF 922 over at the Watercooling forum
"Anyway, you might want to check out this post over at XS. Otherwise, the best option is mounting one radiator externally. I would probably buy two XSPC RS240s and mount one inside the case at the top and the other off the back."
"If you get a thick rad like a feser or black ice gtx 360 with 1 or 2 single rads you should be fine. It wont look as clean with the extra tubing but you should be getting the extra cooling power you need"
I'm a complete noob to watercooling and I really have no clue what to do, and I just want to make sure that I get all of the right parts that can support this setup all at once
