Buyer rule
Start with socket support, case clearance, radiator space, and fan control
Choose by 280mm radiator support, fan thickness, tube reach, top or front mount clearance, socket brackets, and fan control needs.
280mm AIO prices
Use 280mm AIO lanes when larger fans fit the case and noise target
A 280mm AIO can be a strong balance, but 140mm radiator support is less universal than 120mm layouts. Check the case mount before choosing the cooler.

Risk
Avoid buying a cooler before checking the full case layout
The common mistake is assuming 280mm fits wherever 240mm fits, even though the case width, top clearance, and front bracket can differ.
