PWM fan problem

[Grandmaster Fap!]

Lo guys, strange prob, just bought two Bitfenix Spectres to go with an exact other that came with my case i got a while ago.
Problem is, the original fan can be controlled in speedfan ect but as soon as i attach the two new fans to the mainboard, none of them can be controlled and rpms dont register.

All attached to an MSI P67-C45 which in bios can see and control the lone original fan, but same problem, as soon as the others are plugged in, none of them are seen and obviously cant be controlled.

Stumped guys, any ideas?

ps: All three fans are the same part number.

All to separate headers on the board. I looked them up on Bitfenix's site and assumed id just bought none pwm fans by mistake but they are the exact same part number as the one that came with my case and that can be controlled, i'm confused Tealc, enlighten me!

Thanks Tealc, the board specs seem to say all the headers are pwm so i guess its a case of send these back and get some proper pwm fans. Shame really as i like the looks of the Bitfenix and they perform well with relative quietness. Any suggestions on a fan that wont break the bank? Bare in mind im a complete sound nazi too
