cpu fan speed normal for idle?

Solution
No not really,

If the board is monitoring the Cpu temp it will automatically increase the rpm of the fan to keep the heat down that builds up when the cpu is under load.

Mine works at that speed, and can ramp the rpm up to 3000 RPM, if the fan is connected to the cpu fan header of the mobo.

Its fine.

If you want to set a faster speed manual assign the speed profile of the fan in rpm in your mobo bios, most boards support the option to manualy set a fixed rpm if required.
depends on the cpu cooler your using. my brick air cooler i have runs at 800 rpm. if your using the intel or amd stock cooler that the standard speed for it. if you want to see if the fan can go lower check your cpu fan settings. if your running a asus bios you can set the fan speed lower. some bios like msi have a temp profile.
