Should I be concerned about 1800RPM vs 2000RPM

post #1 of 7
Thread Starter 
My new CoolerMaster SickleFlow 120mm fan is rated for 200RPM at 70CFM and BIOS shows that it's running at 1870RPM.

Should I be concerned?

No, usually the fan will run a little over/under their rating (usually +/- 10%).

Fans are usually rated to +/- 10%, or sometimes even +/- 15%.

10% of 2000 is 200, so you are within the range of 1800-2200 RPM.

Doubt that'll make a world of difference, anyway.

Ok, I will not worry.

You know us PC guys, some of us get anal over things like this.

I have the same exact fans, and they're running around 1850. Not a problem.
