The Thermal Truth: Cooling Modern Hot Chips

We tested 25 coolers on the i9-14900K furnace

The Results May Surprise You:

Air Cooling: Noctua NH-D15 keeps i9 under 95°C in gaming (matches 240mm AIO)

AIO Liquid: 360mm needed for sustained all-core workloads

Custom Loop: 10-15°C better than best AIO, but costs more than some CPUs!
Noise-Normalized Testing (40 dBA):

Best Air: Thermalright Phantom Spirit 120 EVO ($45!)

Best 240mm AIO: Arctic Liquid Freezer II

Best 360mm AIO: EK Nucleus CR360 Lux

HiveHW's Simple Rule:

65W CPUs: Single tower air cooler ($30-40)

105W CPUs: Dual tower air or 240mm AIO

125W+ CPUs: 360mm AIO or custom loop
