I just built this new rig and used the FX4300 stock fan.

To test it before installing the OS, I turn on the unit and the CPU fan comes on immediately, then stops for 4 secs, then starts again (sometimes smoothly and sometimes with a hesitation).

It's the same pattern every start. Is it defective or going through a test?

The newer CPUs have multi power planes and advanced fan control based on CPU temp. Your mobo may also have fan speed adjustment in the BIOS. Once you're up and running you can adjust the BIOS fan speed if need be.

The OE fans run at higher speed because they are smaller sized than aftermarket fans and heatsinks. The fan noise is annoying to some folks so if you have a BIOS adjustment then you can adjust it so that you have proper cooling under max load like video games or stress testing and it will run slower and quieter when under light loads. The HSF will constantly change speed as load and temp change on the CPU.

OK. But I've never seen a fan stop immediately. Usually they start then slow down later. Not turn on then off immediately. I would prefer not to spend all the time to format this thing with a bad fan, then have it burn up on me.

Does the fan cycle on and off or does it just shut off after a few seconds and not come back on? The fan doesn't need to blow if the CPU isn't hot. It isn't going to burn up on you. It will shut down if it gets too hot.

The fan's operation won't have anything to do with your formatting the drive. If the fan has some issue you'd just replace it or the CPU assembly. Your drive would still be fine. You don't have to reformat a drive just because you change a hardware component.
