Would this amount of fans be okay?

I have just finished building my new pc and I have 6 fans, but 2 are not working so would 4 be alright?

Four should be enough: Two in the case front for intake, one in the rear and one in the rear roof for exhaust don't put a roof fan in the front location if you're using a tower CPU cooler, it tends to rob the cooler fan/s or airflow.

How come two are not working?

I’m not sure, they’re all connected to my motherboard and I swapped the different fan pins around but it’s still not working. Kinda sucks cuz having 6 would of been nice but 4 is fine.

Check the BIOS settings, maybe those fan headers are off by default.

What is the make/model of your case.
Where are the fans located?
What is inside that you need to cool?
What is your idle temperature, and what is your temperature under load?

In general, two 120/140 mm front intake and a single 120mm exhaust will do the job.

It is the rare motherboard that has 6 fan headers.
If you are doubling up using splitters, that could be your problem.

Well I am still making the computer, I still need to install the cpu and the water cooler, but I tested it and 2 fans weren't working so it probably is cuz of the fan headers.
