I'm currently using the Phanteks Enthoo Pro m but want my case to be cooled well. How many more case fans should I get (besides the two included) and what kinds should I get? I would really like LED or RGB fans but on the cheaper side.

As a bonus, what are some case fan configurations I can set up with the pre-installed and additional fans?

What are your current system specs? I have the full size version of your case with a 1080 ti and a 8700k and I only have two 140mm fans in the front and 1 140mm fan in the back and my processor maxes out at about 65c and my gpu never goes above 72c. I would just make sure you get good SP fans for the front because the holes are super tiny and there is a dust filter behind that. But if you want a good fan for cheap I would look at these https://www.amazon.com/dp/B00WB9M40W/ref=psdc_11036291_t1_B01BYB320S

Linus did a test on a pc years ago. With just 1 exhaust stressed cpu was 96c. 1ex and 1in was 84c. 2ex and 2in was 72c. 3ex and 3in was 70c. It gets to the point where airflow effectiveness peaks, anything beyond that shows minimal to no benefits.

You can't cool something lower than ambient temps by mechanical means. A cpu cooler is mechanical process, ambient temp isn't what's outside the case, but what's inside. So the only fans you'll actually need is enough to get case temps close to outside ambient. If you have a hot running, hard pushed pc, 2x2 is pretty much necessary. Mild nvidia gamer 1x1. Pushing AMD 1ex and 2in.

Does this mean you have one pre-installed and one thermaltake in the front? Does this ruin the aesthetics?
Also, are three fans enough to cool the case and how would the corsair sp120 do?

I have two of the ones that I linked you in the front. Then I have one 140 Corsair RGB brushless or whatever they call it in the back. I think for the ethoo 3 works the best because after I removed my two top fans my temps didn't change at all.

Cool, so none of the pre-installed fans are used. How are the pre-installed fans and should I use them?

You can get away with using the pre-installed fans. I just would upgrade them if you want something that looks better, is a bit quieter, and pushers more air. But amazon returns are pretty easy, So I would just go ahead and try out whatever fans you want. I just wouldn't use more than 3 atm
