I bought 6 sp120 fans and they are running at full speed. Does anyone know how to turn them down?

I have SP120 fans. Make sure they're set to PWM mode in the BIOS. There is a way to manually get them to directly spin at a certain RPM through DC mode but PWM mode essentially automates the fans to spin at a certain RPM dependant on the speed of your computer in successive waves.

My fans are not directly connected to the motherboard

What are they connected to? If they're connected to the PSU through molex or something, I can't help much.

I'm going to assume you have your LED fan hub cables connected though, at least?

Yeah it’s connected to the led fan hub. The 4 fans are connected to the nzxt kraken (aio) splitter which is connected to the sys fan 1 header and the other 2 are connected straight to the other 2 system fan headers.
