cpu already has its fan so i mean about the fan that attaches to the case, it is neccesary? what other components do overheat apart from the cpu?
it is neccesary to install a chassis fan in my pc?

It really depends on the case itself, the balance of the components and the natural airflow available.
Almost everything generates some form of heat inside your case, although some components more than others.
Your motherboard/VRMs can get hot, although for stock operation in a relatively spacious case, should be fine generally.
Your GPU will be the biggest culprit.
Either it's an open design, where hot air is being expelled into the case - potentially heating up other components (as the CPU fan is cooling the CPU & trying to push all the warm air out)
OR
It's a reference/founders/blower design where it draws in air and expels out the rear of the card/case. In this situation, a case fan *may* be beneficial providing a flow of 'cool' air that the card can pull in.

won't use additional video card cause i will use a cheap apu, and i think ram memories have their own heat sink, i have heard that amd heats a lot that's why i'm asking this

VRMs on the motherboard along with RAM etc will all generate *some* heat, although likely relatively small amounts.
Heat spreaders etc don't stop heat getting into the case - the components generate heat, and it has to go somewhere.
It'll depend what kind of CPU cooler you're looking at too - a stock unit blows onto the CPU cooler, so heat is just going to disperse in the case...... leaving heat to escape of it's own accord naturally (and you'd benefit if there's openings on the top of the case as heat rises).
If you have a tower cooler that blows through, front to back, that'll help remove most of the heat directly out the rear.
Test it. Don't install a case fan and monitor temps. If they stay in "safe" ranges, you're fine without. If something gets a bit above safe/normal temps, then install an exhaust and see how things look afterwards.

A PC needs a little bit of airflow otherwise the case will just keep getting hotter and hotter.
It's basic thermodynamics. You remove heat from a hot component, but that heat has to go somewhere.
Preferably out of the case.
You can buy a fan for less than $5.
Why wouldn't you want at least one?

It's not necessary to have a case fan for your configuration but I still recommend it. The reason being is that heat can really build up in an enclosed space like a PC case unless your case has plenty of ventilation. Like Barty said you can test it out and see how it does. If you are comfortable with the temperatures so am I. Still let us know the temps though. Just in case.

found this tipical led fan, will it be enough? https://articulo.mercadolibre.com.mx/MLM-590284620-ventilador-eagle-warrior-halo-led-azul-120mm-para-gabinete-_JM (spanish page)
