The scheme:

The PC:
CPU-Z

MB - ASRock X870 Pro RS
CPU - 9950X3D
RAM - 64GB DDR5@6000-30-36-36-76
SSD - SN7100 2TB + Aorus Gen4 2TB
GPU - ASRock RX 7900 XTX Phantom Gaming
PSU - XPG Cybercore II 1300W
Chassis - Thermaltake Core P8
______________________________________________
The parts for the custom loop:
GPU WB:
Bykski RX 7900 XTX Taichi

CPU WB:
Bykski CPU-XPR-CU-M-V3 (copper body)

Radiators:
3x180mm Alphacool XT45 (45 mm, 12 fpi)
480mm Bykski RC-30 x2 (30 mm, 14/16 fpi)
420mm Bykski RC-28 (28 mm, 14/16 fpi)
120mm Corsair Hydro XR5 (30 mm, 16 fpi)

Fittings and Tube:
Bykski Soft Tube Fitting Kit, 16/10mm (soft tube 3m, fittings x8, 90° fittings x4, plug x2)
Hose Cutter x1
Alphacool HF 16/10mm, 90° x9
Bykski fitting (Male To Male) x3
Bykski Expansion 22-31 mm (Male to Male) x1
Bykski Ball Valve Kit (B) x1

Coolant:
Alphacool Ultra Pure Water 5000ml (x1)
Spray Bottle 500ml

________________________________________________________
I already have the distro plate Corsair Hydro XD7 (with Xylem D5 Pump), which will be mounted on the backside of the chassis.

The fans:
180mm - SilverStone AP181 (x3 for the 3x180mm Alphacool XT45)
140mm - Arctic P14 Max (x3 for the 420mm Bykski RC-28)
120mm - Arctic P12 Pro (x4 for the 480mm Bykski RC-30)
120mm - Corsair RS120 Max (x4 for the 480mm Bykski RC-30)
120mm - XPG Nidec Vento Pro 120 (x1 for the 120mm Corsair Hydro XR5)

Probably all of the fans will be in a push configuration.

Also, the Sorandy LSJ-ZNRB flowmeter:


Thermaltake Core P8 will be heavily modded in order to accommodate the radiators and the Corsair Hydro XD7.

The questions:

1. Do you think that Bykski RX 7900 XTX Taichi (A-AR7900XTX-X) is compatible with my RX 7900 XTX Phantom Gaming (RX7900XTX PG 24GO)?

As far as I can see, Taichi and Phantom Gaming use the same PCB, but I am still worried about compatibility issues.

2. How much coolant would I need? Is 5 liters enough?

3. Do you know if Bykski soft tubes are any good?

4. Do you think that I am missing something?

This will be my first custom water-cooling loop, so any advice or suggestions are welcome.

1 Not sure, have you checked Alphacool offerings?

2 5 would be enough.

3 Not sure, is it EPDM?

4 I would lose the RS 120 radiator. And if room allows, use the 45 AC at bottom and or just remove top, or bottom if there is little airflow clearance. Does bottom have an air filter slot with case?

5 When you say push configuration, do you mean as intake or exhaust? Also will the distro plate allow for a second pump?

1) It may be. The PCB is extremely similar, and other blocks like Alphacool work on both. I'd recommend taking a close look at PCB shots of both to see if there are any component differences that may interfere with the z-height of a block.

2) Initial guess is somewhere around 2.5-2.8 Liters. But you want to have extra, 5 liters would make sure youre absolutely covered, especially if some leaks or you have to do anything that causes you to lose coolant like replace tubes, remove and reinstall a component, etc.

3) I don't, but I'm going to shill EK ZMT because I've used it for years and it is basically indestructible.

4) Without fail, you are virtually guaranteed to be missing something and you'll never figure it out until you're putting it together. Maybe the tube routing doesnt work the way you planned, maybe the parts have tolerances and dont fit exactly the way you planned. Maybe you make a mistake cutting tubes and end up without enough. I'd say you just need to go in expecting to run into a blocking issue when you go to build the first time.
