Cooling the APG-80 compared to APG-83

My search-fu has failed me. I did find that the NG APG-83 SABR as installed in the Viper requires about 5.5kW of cooling capacity, which is (marginally?) supplied by an ECS duct (i.e. air-conditioned air), which removes heat from a heat exchanger installed as part of the APG-83 itself. (The actual APG-83 cooling system being of the self-contained liquid variety.)

I know the APG-80 has a longer range than the -83, and it required an upgraded cooling system, specific to the F-16E/F Block 60 jets. But I have not found any reference to how much power the APG-80 draws, or what its waste heat is.

Can anyone tell me or point me to an URL or reference that documents how much power the APG-80 draws and/or how much excess heat must be dispersed?

TIA

Power consumption can be calculated from t/r modules output and PAE.
AFAIK there isn't any information about APG-80 cooling, but IMHO you can deduce from APG-79
