New CPU/mobo. Very high CPU fan speeds

Same old heatsink, but after installing a new mobo and cpu, the cpu fan is running really loud at all times. I reinstalled windows and it made no difference. The same heatsink on a different cpu was very quite.
CPU is idling at around 42c? Seems high, but maybe not. Tried stock heatsink and it shot up past 52c.
Motherboard is the MSI 970-G43. Processor is AMD FX 8320.
Any ideas?
Latest bios.

Hello... check your BIO's settings for your CPU Fan... you want PWM mode... or Quiet mode is a different option, ETC...

If it's really unbearable, you could use SpeedFan as a workaround to lower the fan speeds. Then you could better search for a solution in peace and quiet :p 

You could also look through BIOS for some options on fan control.

However, you may not even have a problem. It could be that your FX 8320 just needs the fan to run that fast to keep it cool. What was the processor before you switched?

This is what you should do, lower the fan speed with SpeedFan to a tolerable level and monitor the core temp. If it spikes, then your problem is that the processor is just running hot and needs high fan speeds for safe temperatures.
Is the heatsink installed properly? Poor contact could be forcing the fan to compensate for the bad heat transfer.

Best of luck!

(And of course always take temperature readings under load. Idle temperatures never mean much. Keep in mind that your processor cannot safely handle temperatures above 65 C, which is the max)

new cpu runs hotter. what did you expect?

52c at idle? or being used?......... are you using thermal paste........ new thermal paste?

what was old system/what is new system?

is that 8350 even supported on that board?................. or is there even a BIOS update for using that cpu on that board?

I don't see the options for pwm or quiet mode. I have cool n quiet activated however.
The old process was a phenom IIx4 overclocked at 3.8ghz, and it ran much quieter. The new cpu with a lower wattage should theoretically run cooler right? The cooler is a fairly beef Xigmatek Nepartak.
Running speedfan, the fan (pwm1) was set at 100%! Turning it down offered a much quieter experience, but it's not a solution.
temp 1 is at 37c, 2 at 44c, and 3 at 24c. Not sure which is the cpu, but these temps are at a 68F room at idle.
Temp 2 is over 65c just installing some applications...if that's the cpu core something is definitely wrong.

reset cmos.................. save you from having to mess with voltages in the BIOS.

when you reboot, go to the task manager and see how many cores are seen........being utilized........at idle and under usage.

ARE YOU SURE THAT BOARD SUPPORTS THAT PROCESSOR?

If this is his Motherboard, then yes. The FX-8320 is supported.

@windblownmonkey
Why is SpeedFan not a solution?
And I would recommend you make sure the heatsink is properly installed.

As for which temperature is which, if they're CPU related, none can safely be >65C.

Also check temperatures with HWMonitor. It's always good to cross-check a software's accuracy with other software.
