Hello po mga experts. Wanted to ask about car radiator cooling fan (pls correct me if im wrong).

gawain ko magopen ng hood ng car when I get home para mas madaling lumamig. When I turn off the engine and say for about 2-3 minutes pag switch ko to ACC, may naririnig akong tumutunog sa may hood. When I checked it out, nakita ko umaandar ung cooling fan. Pinabayaan ko last night for about 10 mins para mas mabilis lumamig. Is this advisable? Do you do this also sa car nyo?

TIA.
