I'm setting up my PC cooling and could use some advice on the fan configuration. Here are my specs: I'm using an i9-13900K CPU, RTX 4070 GPU, MSI Z690 Pro DDR4 motherboard, and a Fractal Design Define R5 case. I'm planning to mount the Arctic Liquid Freezer III 280 as a front intake with its two fans behind the radiator in a pull configuration. I will also have one Fractal X2 GP-14 fan as a rear exhaust. My question is whether I should add two more Fractal X2 GP-14 fans in front of the radiator, creating a flow of front fans to the radiator and then the Arctic fans, or if that's overkill and could negatively impact airflow or temperatures. Thanks for your help!

If there are no space limitations, adding more fans could be fine. In the past, adding extra fans would significantly help, but modern components are so well optimized that it might not matter as much now. However, installing extra fans on top for exhaust alongside the rear fan could improve airflow more effectively.
Consider putting the cooler on top as an exhaust. The Fractal Define R5 can get a bit restricted in airflow, and adding a radiator at the front might worsen that. While a push/pull setup can help with temperatures, in practice, the difference is often minimal and might not justify the extra cost for additional fans.
