Hello
I'm planning to set up a liquid cooling system
for an Intel I5 4570 3.2 CPU and later adapt a system to my card
A Sapphire AMD Radeon HD7950 3Go GDDR5
So what pump flow rate should I choose?
Is it okay to have a flow rate between 400l/h and 1500l/h, which seems a lot?
If you know a good system?
I'm looking on docmicro and aquatuning.

Hello
The announced flow rate must be without resistance.
And several brands come from aquaristics with large amounts of water.
For example, at Eheim we use the 1046 and 1048, which are the smallest in the range. 600l/h for the 1048.
The greater the height difference, the lower the flow rate.
The flow rate is also hindered by waterblock components and radiators. Elbows and pipe diameter also affect resistance.
The pump's power must therefore also be sufficient for circuits with high resistance. But it must remain compatible with a PC power supply.
The principle is that the flow rate must be very high for the temperature difference across the entire circuit to be less than 1°C. In this way, the order of components no longer matters; the water can flow from the CPU to the GPU without issue.
The large size of the radiator is very important for efficiency and silence.

This kit has a 480 radiator (4 fans 120) and uses a pump with 1500l/h

Pump presentation: the speed is actually adjustable to finely match the circuit.

The case is a COOLER MASTER - RC-K350-KWN2-EN, so 240mm radiators won't fit, which leaves me with little choice but to go for 120mm systems.
Unless it's possible to have an external installation.
Here is the system that seems good to me, although the reservoir is a bit too bulky for my taste, flow rate 1500.
Complete Watercooling Kit NexXxos Cool Answer 120 DDC/XT flow rate 400, probably not bad for the CPU only?

Hello
For once, a beginner doesn't want to modify a sealed kit, that's good.
So, the case is too small to fit more than a 120mm radiator: just drop the radiator inside the PC.
So are you going to completely change the PC to water cool the graphics card later?
Or are you going to make a monoplan airplane right away, with a big radiator sticking out everywhere that isn't too thick? It's cheaper and you can put one 140mm fan that’s quite silent. NexXxoS XT45 Full Copper 560 radiator at 95.20. For cooling, it's the best: outside cool air cools the radiator and goes up to the ceiling. Aesthetically, it’s monstrous; we can’t ignore that you modified the cooling. When idle, the fan might not even spin or hardly at all.

Later on, add a complete water block for the graphics card, modify the tubes, and add some quite silent fans if needed on the radiator (up to 4 in 140mm).
If you immediately bought a large adjustable pump, it will remain for the graphics card.
It might be a bit more expensive right now, but it minimizes what you need to buy later to water cool the graphics card without removing anything except some bits of tubing. Hyper silent for the CPU alone, it shouldn’t be too noisy with the water-cooled graphics card. And if you change the PC one day: radiator, fans, and pump can be reused.
Disadvantage: you have to tinker carefully. Advantage: you have a chance of cooling better than air cooling. And you can overclock without changing your little case if you want.
The radiator attachment to the case can look something like this:
