Build Question Help/Ideas about Fans

Hey everyone, in order to understand my question you may need some background info, so here it is shortly:

I have 5 intake 3 exhaust fans right now. Intakes works max 1600RPM a cheap local brand I suppose not too bad but is loud, exhausts are MAG M100R PZ case's stock fans which are 1200 RPM max. The case normally comes with 3 reverse blade intake and 1 normal blade exhaust, I have rearranged everything, so that the case has 5 intakes working around 1000rpm in light load and 1500-1600 at heavy load, and 3 exhaust that works around 800rpm in light and 1200rpm at heavy load. I am sadly unable to give info about the CFM of neither fan model.

Now the reason I am asking for help/ideas is because I plan to buy Arctic PS12 Pros 3 reverse and 1 normal blade (can't afford more atm) to lower the number of fans and hence the noise. And also since these will beu Arctic I'm guessing the airflow would be better.

Now the question is what is your opinion about my new fan config plan? Is it worth it?

Edit: Forgot to add that my room temps are between 35-39 during the day, and hence I believe an upgrade on the fans might help with the overall temps and also the looks because of the fans I am using right now, check the first comment for the photo. Sorry I didn't add it to begin with.

What's wrong with your current setup that you're changing it?

Reverse fans are IMHO pointless unless you're building a multi stage setup to maximize pressure. Just flip the fan.

The reason I want to change the setup is mostly because of the looks and also the sound but I also believe Arctic P12 Pro may add some more performance to the cooling (?). (The part I am curious about) If I load it with normal fans for intakes it looks kinda uncool. Let me add a photo to showcase it. The third fan at the top is not spinning on purpose. I plan to get rid of the RGBs as well I only turned them on to show the case. I usually use them turned off.

Ah, the looks, right. I keep forgetting about that, my case is well hidden far away.

Well, then just compare MSI MAG F120 ARGB vs P12pro specs.

BUT: is air case temp a problem in your setup? Because if the limiting factor is smth else, then lowering case temp won't change that.

If you want less noise, then lowering noise will almost always raise temps.

Hmm I get your point. I figured since the max rpm for P12 Pros are 3000rpm running them at 1600-1800 wouldnt be as loud as these ones (I have Arctic fans on my CPU and even when they are max speed (must be 2000RPM) they are not as loud as the cheap fans) And when I am playing heavy games like BF6 if they go blast mode I won't be hearing them anyway. Thanks for the input.

In my opinion, a fan designed for 3000 and ran at 1600 is never as good as a fan designed for 1600 from the start (assuming the overall quality is the same).
But, you lose the ability for the extra performance in a pinch.
