Pc case side vent blowing cold air out should I cover it over?

Hi
I am wondering if I should possibly cover my side vent (left side) on my case as its blowing cold air out of.
Basically I have 3 fans in the case. Two front 1 rear.
The front 2 are Noctua NF-F12PWM Case Fans 120 mm and the rear is a Noctua 120mm one.
It feels like the 2 fronts are blowing the cool air obviously into the case but im losing some or a lot via the size vents.
I am not having any overheating issues but its just something that is niggling me.

Any ideas or comments on what I can do or should do would be appreciated!!

    Skin is a relatively bad indicator of moving air temp.
    It might feel 'cool' to you, but in reality, that is evaporation on your skin.
    The actual air temp is almost certainly warmer than what it feels.

    Cool air coming in, warmer air going out. This is the way it should be.
    Leave it as is.
