This is the Rig i am planning and as a sugestion in my othere post I think it will be good to get some water cooling in the system big enugh case and i think its about time i do my first water cooling Loop . 6gb 1600Mhz 9-9-9-24 ram 750w corsair Nice power suplies all i read about them is BUY BUY Corsair 800D PSU Lite on blue ray/ dvd 2Gb xfx 5970 intel i7 930 GA-x58-ud3r 120 gb ocz RevoDrive Price is at £1.737 Thats the rig i got 2000 to play with and just need the water cooling now but i know nothing i am sure i will be fine putting it in I just need the componants to do it. It will be a great great help.
I would highly recommend you take a look at cooling configurator, you can create a virtual loop and it will help you detemine what parts would fit your hardware. Site run by EK, so expect only EK blocks. Hope that helps. 1Thing you will want to make sure of is to try and keep all your water blocks as the same material (ie copper only) to prevent any cross metal contamination/corrsosion.
I'd suggest running a seperate CPU and GPU loop considering the Corsair case can't fit a huge radiator like some cases. For the CPU loop, I would strongly advise having a 360mm radiator in the top with scythe Gentle typhoon 1850rpm fans fitted. You should then add in the swiftech mcp 655 pump for maximum flow rates, and probably 1/2" ID 3/4" OD tubing. As for the CPU waterblock, you can't go wrong with either an Apogee XT or Heatkiller 3.0. You can then choose whether to have a 5.25" drive bay reservoir, EK multi option cylindrical reservoir or perhaps even a simple T-line. For the GPU loop, you can fit a 240mm radiator in the bottom area of the 800D, again with the Scythe Gentle Typhoon fans. Because of the potentially massive vibrations coming from using another MCP 655 pump, a DDC pump would definitely do the job for the small loop and would take up far less space. You can then pick up any 5970 waterblock and install it, but I would suggest looking at the EK FC5970 and Razor 5970 blocks especially. For the reservoir, you have the same choices as before. For a build like this, I would suggest buying 2 litres of coolant just to be safe, as well as using compression fittings when possible. I have no idea whether that helps or makes you more confused, but thats what I would do in this situation.
What shocker said, but I would switch the 360 and the 240mm rads round, so the 5970 is being cooled by the 360mm rad. Oh, and maybe make it 3 or 4 litres of coolant, my loop, only a CPU and 120+240mm rad uses just over 1 litre.
A 240mm radiator can't handle the high temperatures of a 4GHz core i7 like that of a 360mm, so I think its a better idea having the best possible cooling on the CPU. Even with a smallish radiator, the load temperatures of the 5970 are going to be in the region of 30-40c cooler than that of stock cooling, which is more than enough to overclock the card and keep it well under 60c.
