CPU Fan Problem

Hello,

Here's my system:
Asus p8z77-vpro (Newest version bios updated) 1504
i5 3570k (stock) + CM Hyper 212+
16gb 1600mhz
120SSD Intel 520
1 TB HDD
Blu ray drive
Raidmax 850w psu
Thermaltake mk-1

My problem is with the settings on the motherboard with the CPU fan. I can't change it, it won't let me. As soon as windows starts the cpu fan automatically goes to full speed and I can't turn it down. As you can imagine it is pretty loud for a silent pc. This all started when I updated to the new bios from the 12 series to the 15 series. I really don't want to downgrade the bios because I was getting BSOD with the 12 series and lower. As of right now I can't control it via bios and asus's fan xpert 2 shows the fan and its speed but won't let me control it like i can with the other fans.

Any help or suggestions is appreciated.

Thank you.

Did you do any overclocking with this motherboard or cpu?

Only thing i had to change settings wise was the memory speed form 1333 to 1600mhz that is it.

& I'm going to flash back to bios 1206 i will post back if anything changes.

Edit...

It won't let me flash back to an earlier version because it says the inner frame work has been changed. I guess I'll just have to wait till they release a new bios that hopefully fixes it.
