Should I seal Up All These Holes In My Case?

In the front alongside my 120mm monster there are all these smaller holes. Also Behind My Proc I have an 80mm Exhaust....but running next to where I mounted it are a ton on small holes. I also have one of those horizontal card coolers as an exhaust...and was wondering if I sealed up all the holes pressure would be better for cooling (i.e. air only has one place to go) If anyone can reccomend this with experience please let me know.
I sealed up all the extra holes in my case and have positive pressure (more going in than out) and it helps my case temps. My CPU temp isn't really involved because it's watercooled and I have air from the outside coming in throught the radiator, but it did help my case temps.
I used clear packing tape to seal off all of the holes in my case. Helps pressure and there are fewer places for dut to enter. I didn't test before temps because I taped them as soon as I got the case. My system temp is ambient +2C
