I am currently pondering the possibilities of watercooling my current computer. The problem i have is what parts to get i order to make sure that the new setup is as quiet or even quieter that what i already have while getting more cooling (lower temps or overclocking) first things first, my current hardware (and its cooling) CPU: I7 920 with a Nocuta NH-U12P SE1366 with the fasn spinning at 800 rpm. GPU: 2 x HIS radeon HD 6950 with a Artic cooling accelero extreme + II (fans contorled by hte cards), these are not reference PCB Case: CM stacer 830 MB: MSI X58 Pro-E As you rightly deduced from my HW, this is not a new computer, but it has no problems running all my games at the desired resolution. But there may come a time (a year or so) when some or all of the hardware will be replaced with something faster, so all the blocks need to bee universal (plan on using the same WC setup for a long time). there is also the added problem of me living in Norway, hence no interest for shops that operate in the US, and only if the price is noticeably lower for shops in the EU. primarily because of the rather good consumer protection here (component that breaks within five years of purchase are either replaced by the shop or you get your money back) My plan is to put the radiator lying outside the case(see attached file). More spesificaly i had this rad in mind magicool 2 x 3 x 120 with the EK supremacy CPU block and two EK supreme GPU for the two HD6950s I already have 6 of the Arctic Cooling F12 pro fans to run on the radiator, But i am a bit indecicive as to what kind of pump i should get. these are the different pumps at the store i found in Norway, but i am open as to getting them from other sources. I was also planing on using Quick Disconnect to be able to sepperate the case and rad/pump assembly. (these and these. I was also thinking of splitting the tube after the pump and running a all the three blocks in "parallel" in stead of in "series", is this a good idea? i plan on using 1/2" ID 3/4" OD tubing. so to recap, Need help getting a (one or several) pumps (preferably from Norwegian e-tailer) and hints on the layout. the budget for this setup approx 6000 - 7000 Kr (with todays exchange rate puts it at 1000 - 1200 USD) but it is not fixed. Anny help appreciated.
