Question 7 fans connected to 1 system fan port?

[machadinhos]

Hi everyone!

I'm currently building a PC. The PC has 7 fans and I bought an PWM controller to control them all. I'm using the MSI B760 GAMING PLUS WIFI motherboard.
I wanted to know if I can connect the controller directly to a system fan port on the motherboard or if it's to much power for just 1 system fan port.
If 7 fans in 1 system fan port is too much, how many can I connect in a single port? (the motherboard doesn't have 7 system fan ports, only 5)

Each fan is rated for 12 volts.

Here is the motherboards manual in case someone wants to take a look:

Thanks for the help!

I believe that each fan will draw a certain number of volts and the total should not exceed 12v for one port. I am curious to know also and have researched somewhat for my own build. I decided to use a single y cable for two fans sharing one port. Does your pwm controller need to connect direct to the board?

It's the amps x the volts "12" to figure out how much power all those fans will pull from that single fan header. What does the manual say that header can do ?

oh...didn't know that, sorry...
That's the problem, I couldn't find anything in the motherboards manual...
I'll leave the link to the motherboards manual here if anyone wants to check it out:

The controller has a PWM cable to connect somewhere...so I assume yes.

What PWM controller did you buy?

I'm not sure there are any fan headers that are going to power 7 fans by itself. I'm surprised your PWM controller didn't come with a SATA power connector.
