Is an air cooler or an AIO liquid cooler better for gaming?

Both can keep a gaming CPU well within safe temperatures. A premium dual-tower air cooler like the Noctua NH-D15 or be quiet! Dark Rock Pro 5 is generally quieter and has no pump to fail, while a 360mm AIO like the ARCTIC Liquid Freezer III 360 tends to offer more thermal headroom for the highest-TDP chips and keeps heat away from the motherboard socket area.

Do I need a 360mm radiator for a gaming PC?

Not necessarily. A 240mm or 280mm AIO, or a good dual-tower air cooler, is enough for most mid-range gaming CPUs. A 360mm radiator becomes more valuable with power-hungry flagship processors or if you plan to overclock.

Will a big air cooler block my RAM slots?

It can, depending on the cooler's fan height and your RAM's heat spreaders. Check the cooler's documented RAM clearance and your memory kit's height, or choose low-profile memory if you're set on a large air cooler like the NH-D15 or Dark Rock Pro 5.

How important is CPU socket compatibility when choosing a cooler?

It's essential. Always confirm the cooler's mounting kit officially supports your CPU socket (such as AM5 or LGA1700/1851) before buying, since brackets and backplates differ between platforms even within the same product line.
