Cooling tips
Keep intake filters clean so CPU and radiator fans do not ramp unnecessarily.
In BIOS, try a slight undervolt if thermals or noise are high—stability test afterward.
For AIOs, mount the radiator so air bubbles do not sit on the pump (usually tubes down on front intake).
Installation
Large coolers may overhang DIMM slots—check RAM height and first PCIe slot clearance before ordering.
FAQ
Should I choose air or AIO for this CPU?
Choose air for value and simpler installs. Choose AIO for stronger sustained thermal headroom if your case supports radiator placement.
How much cooling headroom is enough?
Aim for a cooler class above your sustained load target so boost clocks stay stable and fan noise remains controlled in long sessions.
What compatibility checks matter most?
Verify socket support, tower height or radiator length, RAM clearance, and case airflow direction before purchasing.
