Two 80mm fans enough??

[dms2425]

Well , I'm gonna order the parts for my new computer really soon , so I was wondering if 2 80 mm fans will be enough?
This is the case ,it brings two 80mm fans

and this is the PSU , it has 1 120mm fan

The proccesor already has fan and heatsink and the gfx has also fan and heatsink , should I buy a 3rd fan ?
oh , I'm gonna be running an amd 4000+ , radeon x850xt , 250 gb hd , 2 gig or ram just in case you might wonder if its gonna get really hot.

if you can get a 120mm fan in the case that would be good.

if you're not doing any overclocking, it should suffice, but there is no harm at all in adding airflow. It can only help.
