Hi guys, obviously I’m new here, but I've been reading a lot or the past few weeks! I’m planning to buy a new build; my current PC is 6 years old and struggles to keep up. Before I list all the components I want, here is what I’m interested in: Performance and Silence. I’m not interested in looks; no one will ever see the inside of the PC. This rig will mainly be used to play games. I’m not planning on changing it or at least 6 years, so it has to be durable. The new rig will support a dual 4K display B) , so I’m planning on overclocking my GPUs. Obviously I’ll be overclocking the CPU, so I’ll be water cooling everything (for the first time). The OC won’t be extreme though. So here is the build itself: Case: Corsair 900D Fans or the case: 3*NF-S12 PWM Motherboard: Asus Maximus VII Formula CPU: Intel 4790K 2*GPU: EVGA GeForce GTX 780 Ti Dual Classified (SLI) RAM: G.Skill Trident 2 * 8 GB / CAS 7 / 1600MHz System storage: Asus ROG Raidr Express 240 GB Additional storage: Samsung 840 EVO 1Tb 2*Screen Display: Asus PB287Q (Dual 4K display) PSU: Corsair AX1200i (1200W) And this is the water cooling equipment I’m planning to buy: Waterblocks:CPU: EK Supremacy Elite - Intel 115x 2*GPU: EK-FC780 GTX Ti - Acetal+Nickel 2*GPU backplate: EK-FC780 GTX Ti Backplate – Black Motherboard: Built-in Asus Maximus VII Formula block Pump: EK DDC 3.2 PWM X-TOP CSQ Radiators and fans:Alphacool NexXxoS XT45 240 + 2*NF-F12 PWM (PULL) Alphacool NexXxoS XT45 120 + 1*NF-F12 PWM (PULL) Alphacool NexXxoS XT45 480 + 4*NF-F12 PWM (PULL) Alphacool NexXxoS XT45 480 + 4*NF-F12 PWM (PULL) Reservoir: EK Waterblocks - Reservoir - 250 x 60 mm - EK-RES X3 250 Tubing: Primochill PrimoFlex Advanced LRT 3/8" ID - 5/8" OD / Crystal Clear 20* Compression Fitting: Alphacool Shiny Copper 3/8" ID - 5/8" OD (4 rads + res + pump + CPU + 2gpu + mobo)*2 Coolant: Distilled water + silver kill coil In Loop temperature sensor: Phobya The pump and all the rad/case fans are PWM and will all be controlled by the motherboard. What would be the best setup or this pump on CPU header? Obviously I don’t care about LED / fancy fans / dyes and so on. What I do care about is: Is this water cooling build consistent? Is 1 DDC pump enough? Did I miss something important? What do you guys think about the overall build? Do I need to add some kind o a draining closed tub somewhere for future maintenance ? Thanks a lot
