5 case fans but only 2 fan header on the motherboard

Hello... It can be dangerous to do this to the MB output AMP from over current and Loss of Digital control... They make "FAN controller's" that connect directly to your Power Supply for this purpose... Typically that many Fans are not Needed to operate your PC... B / do you have possible High heat Component System? OR high Operating Environment?... B /
 


Well I havent bought any of these(planning to buy) and no i will just make a midrage system for rpg gaming and school work.I just thought it would be good to have as many fans as possible to make my pc last longer since I am not a rich guy to change components each year.Keeping low temps is way better from what i know.
