Should I get a 280 AIO and mount it at the top of my case or get a 360 AIO and mount it at the front of my case

[SircarrotII]

I am debating wether getting a 280 AIO and mounting it at the top or a 360 AIO and mounting it at the front. If I mount it at the front, I am worried about temperatures with the GPU and other components when mounting the 360 AIO at the front but the CPU temperatures could be affected If I mount a 280 AIO at the top. I am also worried about lifespan as I can't mount the AIO at the front with the pipes facing downwards. I am also planning on overclocking my GPU and CPU. Which AIO should I get? Case: Corsair 4000D airflow, CPU: I5-9600K, GPU: GIGABYTE GeForce RTX 3060 Eagle OC AIO: Any well performing AIO with RGB that fits LGA1151 (Either 280 or 360)

With a 9600k, either will be fine. Probably more than enough. Just buy a good one from EK or Arctic.
