Thermaltake TH120 V2 ARGBcomputed

Coolant temperature this AIO settles at over fan rpm, its dissipation in W/K, and the noise of its 1 stock fans. Calculated from the radiator size and thickness and the stock fan's datasheet with the RadiatorTemp model. Not measured; the bands show the spread.

How these numbers are computed

A radiator moves heat in proportion to the difference between coolant and incoming air: Q = q · (T_coolant − T_air). q depends on the air actually passing through the core. Airflow per fan is CFM_max · derate · rpm/rpm_max with the radiator derate (0.62, or 0.72 for pressure-optimized blades) times the core-thickness factor. Per 120 mm segment at 27 mm: q = 8.5 W/K · (airflow / 45 CFM)^0.6; heat transfer over fins scales with roughly the 0.6 power of velocity.

Core	Airflow factor	Fin area factor
27 mm	1.00	1.00
30 mm	0.97	1.09
38 mm	0.90	1.15
45 mm	0.84	1.22

Thick cores gain fin area but lose airflow; at low rpm the net is close to zero. With fans off, natural convection is taken as 1 W/K per segment. The band is ±15 % on q: fin density, coolant flow and preheated case air. Pump speed matters little above roughly 1 l/min. Noise is the stock fan's curve plus 10 · log₁₀(fan count).

Air entering the radiator is case air, usually 5 to 10 K above room. Die temperatures sit above the coolant by the block and TIM delta, typically 25 to 45 K under load. Nothing here is measured; the same model runs in RadiatorTemp.
