When air is better

Reliability: No pump to fail. Great for long-lived rigs and travel.
Noise: Premium dual-tower air coolers (e.g., Noctua NH-D15) are quiet at moderate loads.
Maintenance: Dust occasionally; no liquid worry. Fits 65–150W CPUs easily.

When AIO shines

High wattage: K/X3D CPUs boosted + high-end GPUs benefit from 240–360mm AIOs.
Case constraints: Small clearance around RAM/VRM? AIO moves bulk to radiator.
Top exhaust setups: Great for cases with strong top venting to remove CPU heat.

For most midrange builds (i5/R5 non-K), a quality 120/140mm tower cooler is plenty. AIOs pay off when sustained loads and OC headroom matter.

Noise & fan curves

Set a gentle fan curve: 40–50% until 70°C, then ramp. For AIOs, keep pump speed steady (70–100%) and let fans scale. Use case intake filters to keep radiators clean.

Compatibility checklist

Case clearance: Check cooler height (air) or radiator slot support (240/280/360mm).
VRM/RAM height: Low-profile RAM helps big air coolers.
Socket kit: Ensure AM5/LGA1700 brackets are included.
