Will this be sufficient for airflow?

[Tanaz]

So basically my PC was getting choked out because it didn't have enough airflow and it had only 2 case fans and my case was made for watercooled CPU'S and had only 1 fan hole (but 2 fan holes on the chasis I'm guessing it's a common chasis made to save money for multiple towers). I cut the front panel's plastic to make room for another fan and put a second fan in the back top section for exhaust. However I didn't want my front fans to stay exposed so I removed the metal cover that was initially on the plastic and drilled holes into it. My question is are those holes enough and will they obstruct airflow?

Ugly as hell but it should work. Maybe remove the panel entirely and get some screen door mesh or something?

I'm more of a function over form type of guy. But if I explore your idea, do I just glue the mesh to the plastic?

That looks quite restrictive. I would double the hole density, add one at each of the cross points between 4 other holes. Also make sure there is a bit of room between the fan and the front of the grill. If the fan is pressed against it airflow will be impeded more so.

I'd probably use epoxy or something but yeah. I did a similar thing to my Elitebook 9470M and it allowed the fan to turn off at super light load and temps dropped ten fucking degrees (celsius!).

This is quite a flimsy piece of sheet metal. I'm not sure it won't just give out and bend/ break if I make more holes. I'm so annoyed that the only component that I left for the store to pick for me ( the case) was the wrong one. Adding 2 case fans lowered my temps by 18C on CPU and 10C on GPU. I just don't wanna invest 200$ in another case...

Update: Tested and the temps were not different. Cinebench and XTU stress tests give me max CPU temps of 73-75C (6700k @ 4.4) but Prime95 absolutely obliterates it raising it at 91C almost instantaniously. I feel like Prime95 is insanely unrealistic load.

Not sure what cases you are looking at that are so expensive. There are a bunch of 50$ good cases out there. As others have said just a mesh front is easy to do and will be better than these holes and probably look a little less bad too as a bonus.
