I've played around with the bios settings and nothing seems to fix the problem. I'm somewhat determined to use these fans as I have three other noctua fans in the system. The fans are new and I may have accidentally tore up one box a little so It would be hard returning them and swapping them for the Noctua Chromax ones. Seems I have to resort to MB control.
With the pump using one fan header, I only have 2 available fan headers for 5 fans. I'll have to use a three-way splitter for the case fans which I feel uncomfortable using even though the fans fall under the 1 Amp limit (0,18 A + 0,13 A + 0,1 A). I'll also loose the ability to fine tune each fan for noise.
