The 7800x3d doesnt draw that much power, so any 360mm aio cooler will probably work tbh. Just get one with a decent warranty. becomes more of how you want it to look I think personally. I bought a a35 air cooler for mine as i waited for the new corsair and lian li aio's to come out...still running it as whisper quiet and no problem at all so can't be bothered to change it at the moment..the new arctic freezer 36 below prob best bang for buck as think launch price is £20. works better with intel cpu's but will be fine on the amd cpu also...
the gainsworth 4070super another card to look at. super does have improvements over the non super(unlike the 4070ti and 4080 super variants which are the same), and although £50 more, you do get dlss and better raytracing, which will be playable if gaming at 1440...something to consider if you're going to use it for couple year before getting a 5000 or 6000 card...at 1440, think the 12gb vram will be sufficent for next couple years
