what are your temps?

according to the LED poster, it is 35 degrees currently

Are you using PWM fan? Speed control for the CPU header is strictly PWM based. The rest of the headers are controlling the fans via voltage.

by PWM do you mean it has a 4-pin connector?

It's like Phil says. The easy solution for the non-PWM fans is to connect CPU fan to CHA1 or CHA2 header, turn on Q-FAN for those connectors and put CPU fan monitoring on ignore. This is how I used to run my board.

yes that is what i found too, the fan speed varies when i put it in a chassis fan header... but thats no good for cpu cooling at all since the mobo stays cool while the cpu gets hotter and hotter

i downloaded speedfan in hopes of being able to control the fan speeds that way, but it has no effect... it doesnt even report the rpm of everything other than the cpu... plus the temp readings look way too low to be true
also, the LCD cpu readout is always 2 degrees higher than what it shows under 'CPU' in speedfan... 60/58 degrees running prime95, corsair h50, stock clocks and voltages
::edit:: stopping prime results in an instant drop in temps in Speedfan, but the LCD readout remains constant... i dont think i trust the LCD that much anymore
