Heatsink Thermal Resistance & Junction Temperature
From dissipation, ambient temperature and package thermal resistance, find the θsa the heatsink must achieve and back-calculate junction temperature with the heatsink you have.
θsa,max = (Tj,max − Ta)/Pd − θjc − θcsThermal Design
Fan Airflow Conversion & Air-Power Calculator
Convert between CFM, m³/h and L/s, compute air power from static pressure and fan efficiency, and back out the airflow needed to carry away a given heat load.
P_fan = Q·ΔP/η ｜ ΔT = P/(ρ·c_p·Q)
