Black Goliath

Heroes of this build:

A monitor (TV in total), but still a monitor - LG OLED 55CX3LA

(I did not think about this element for long. OLED just charmed me Emoji No typical computer monitor will show everything like OLED. Unless the OLED monitor ;) )

Case - Thermaltake The Tower 900 black

(initially it was supposed to be Fractal Define 7XL, but when I found TT, I said I wanted the big one Emoji)

Power supply - Seasonic Prime Gold 1000W

(that's enough, in my opinion, for the whole thing including RTX 3090. Titanium wasn't just there, but I wanted to get it, so I bought Gold)

Motherboard - ROG ASUS MAXIMUS XII Extreme

(Here, too, Asus Maximus XII Formula was supposed to be here first, but on reflection, I added some € and bought this one. I still got the promotion of Asus and I will get 150 € back)

Processor - Intel i9 10900K

(There could only be one choice. I have nothing to do with AMD, even once I "sat" on Duron or Sempron, I do not remember. But here is supposed to be Intel ;) )

Memory - 4 x 8GB Corsair Vengeance Pro cl16

(neither is it high end, nor is it a niche product, but I think it's just right)

SSDs Samsung (mechanics not assembled) - 1 x 980 pro 500GB, 1 x 970 pro 512GB, 1 x 860 Evo 4TB, 1 x 870 Evo 4TB

(I removed 970 pro from my laptop - there went 970 evo plus, after some thought I bought 980 pro to take two sockets under the cover of the motherboard)

Graphic card - ROG Asus Strix OC RTX 3090 24GB VRAM

(long-awaited card - more than 1.5 months has finally arrived at my place.I have paid more than about 170 € from an earlier order at, but I am really happy with it. The Asus class in itself)

CPU cooling - Noctua NH-D15 Chromax

(temporary cooling until all the water cooling is built up, and also to test individual components before I start to disassemble the graphics)

Time for cooling.....

A customised cooling loop, and in it:

Radiators - 2 x EK-CoolStream SE 560

CPU block - EK-Quantum Velocity D-RGB - Nickel + Plexi

GPU block - EK-Quantum Vector Strix RTX 3080/3090 D-RGB - Nickel + Plexi

GPU Backplate - EK-Quantum Vector Strix RTX 3070/3080/3090 Backplate - Black

Pumps with reservoir - 2 x EK-Quantum Kinetic TBE 300 D5 PWM D-RGB - Acetal

Fastening brackets for pumps - 2 x EK-UNI Pump Bracket (120mm FAN) Vertical

Sensor for temperature, flow, water quality and electrical conductivity. - high flow NEXT sensor from Aqua Computer

LEAKSHIELD leak prevention system standalone from Aqua Computer

Aqua Computer temperature sensor

Straight fittings - 14 x EK-Quantum Torque HDC 12 - Black

90° Rotary connectors - 6 x EK-Quantum Torque Rotary 90° - Black

45° swivel fitting - 1 x EK-Quantum Torque Rotary 45° - Black

Extension connector - 2 x EK-AF Extender 30mm M-F G1/4 - Black

Extension connector - 2 x EK-AF Extender 6mm M-M G1/4 - Black

Extension connector - 1 x EK-Quantum Torque Extender Static FF 14 - Black

Drain valve - 1 x EK-AF Ball Valve (10mm) G1/4 - Black

Divider T - 1 x EK-Quantum Torque Rotary T - Black

Water filter - 1 x Barrow Inline-Filter G1/4 with internal threads - Black

Green connector rings - EK-Torque HTC-12 Color Rings

Fan - 10 x Noctua NF-P14s redux-1500 PWM case fan

Fan - 2 x Noctua NF-A14 PWM Chromax.Black.Swap case fan

Fan - 1 x Fractal Design Prisma AL-14 ARGB PWM case fan

Hard Tubing - EK-HD Tube 10/12mm 500mm/19.5"

Glass tubing - Mayhems

Coolant - distilled water plus colour - EK-CryoFuel Acid Green concentrate

Paste - Thermal Grizzly Kryonaut

Thermopads - Gelid Ultimate

While I was quite enthusiastic about tube bending, I was not very happy with the bending itself. There are a lot of guides on the internet on how to do it, but I guess I'm impatient (because I try to be accurate). So summa summarum came out as it came out. I didn't like the end result anyway and I ordered Mayhems glass tubes. I will replace the capacitor after the correction on the graphics. I will put them in places that are in view. The pump outlets are hidden low, so there will be acrylics. Generally, for the first time in my life made water cooling, I am satisfied. The whole thing still needs small corrections (sleeve cables, cable arrangement).
All prices added manually converted from the day of purchase at the appropriate exchange rate.

PS. Please forgive any possible mistakes in English. I am from Poland and I do not know it perfectly.
