I'm building a new computer and plan on adding water cooling. I've decided to stick with Koolance for all the parts, and just wanted to make sure this will work.
Case: COSMOS 1000 (OK, this isn't new, but it's a great case)
CPU: i7 2600k (plan on overclocking this of course)
GPU: GTX 590 (1 for now, getting another one later. May overclock, depending on temps)
What I plan on buying:
3/8" Compression (5 pairs)
HX-CU1320V 4x 120 Radiator
BKT-HX001 Radiator Mounting Bracket
15 feet or so of this
A 700mL bottle of this
VLV-XTSPLB Drain Valve
I still need to pick out some fans for the radiator. The setup is a single loop. Pump/res --> Radiator --> CPU --> GPU --> Drain Valve --> Pump/res
Now, for some questions.
- Am I missing something?
- Will a 4x120mm radiator be enough to cool my CPU and *two* NVIDIA GTX 590's (I'll only be getting one initially but plan to move on to two in 6 months or so)? Or, do you think a 3x120mm would be enough?
- With the radiator mounting bracket, can the radiator be extended away from the case far enough to leave room for DVI cables? I plan on mounting the radiator like this image. However, it's a 4x120, so one extra 120 will be hanging below, which is sure to cover up the DVI ports coming from my video card(s). That image looks like it's far enough, just wondering if anyone has any experience.
- How easy is it to drain a system with that drain valve? If it's at the bottom of the loop, will it work well? Will I still have to tilt the system all over?
- When I get my second 590, should I split the 3/8" coming from the CPU into two 1/4" tubes (one for each GPU), or will it be fine in series?
- Will the pump be able to keep up with the CPU and two GPUs?
- Will the different metals for the blocks and radiator affect the coolant? I've heard that you shouldn't mix metals, and if you do you should get some specially treated coolant. Is this still a factor, and do you have any coolant recommendations?
Thanks for any help you can provide me! Any other suggestions are welcome as well.
