New Computer Build

[cpuman101]

I am building a new computer with a MM case and have a question about the fans. I was wondering if it is safe to solder fans together to connect them to a single fan header on the motherboard, and if so how many?

Also if that is not an option what other solutions do I have besides using a 5 1/2 bay fan controller as i will not have one open. i have looked for an internal fan controller but have been unsuccessfull.

Any and all advice is much appretiated.

the rule of thumb is .6A per fan header on a MB that will give 2 med fans. and if they have a tac then dont solder them together just use 1 per set
