Greetings!

I have a fan related issue. I cleaned out the dust in my case, took all fans and components out. I put everything back in. I am stable and everything runs. However 3/ 6 fans will not come back on. All headers and fan terminals work.During Post they all work. However upon logging in to windows I lose Chassis Fan 1/2/3.

They are 3 pin Corsair fans. and a Corsair H100i cooler. According to AI Suite they are on Overheat, CPU is running at 49C while I am writing this.

Also my CPU is not staying at my stable OC settings, it floats between 800mhz a core and 4100mhz a core.

I have poured over the mobo manual, and previous posts with issues similar. I cannot determine if this is a software issue, or some hardware issue that changed while I was taking things apart. My bios options appear to be the same as before i started the cleaning.

Any help is appreciated.
