Right now my CPU is cooled by a Thermaltake LCS that has:

- 350cc reservoir
- 360mm radiator
- P500 pump (500 L/hr), and
- 3/8 in tubing

Now that I'm finding waterblocks specifically designed for my Radeon HD 4870 X2 graphics cards ( I have 2), I'm looking into getting them water cooled as they run hot as hell especially in high end games. I'm just curious, as to what I'll need to add to the system. The pump "should" be able to handle the extra workload. What I'm really wondering is if my radiator will be able to cool the coolant enough, or if I need to add another 1 or even 2 rads. Also I'm wondering if I'll need another (or bigger) reservoir. Any ideas or help you guys could offer would be great as I'm still fairly new to the liquid cooling world. Thanks.

1/2in tubing + possibly a better pump like a D5/MCP655.

Not sure about the rad. You may want to get a 2nd 220 rad to go along with the 360 rad.

Start over. Pump is weak. Rad is poor and unable to remove the heat the card creates. Rad is aluminum probably. There is little you can do besides buying a bigger rad. Then you have poor flow, mixed metals, a CPU block if original prone to failure.

I'll leave it at that.

I have a kandalf LCS with same build im guessing and after 1 year and a small oc (3ghz on q6600) i got max temps of 50 C on load.
Its quite crappy, i know but i simply "Dont need any more".
Id say either save money and replace all cooling in some time if you want to OC mid-heavy, or change rad/cpu block. CPU block first probably since it should have more effect than Rad (on load my water temp is 30 C and max core is at 50C, while on idle my water is 28C and core 35, so clearly that the bottleneck that comes to mind first).
