View Full Version : standard Fan speed
Hello guys
I have 6 Sharkoon Silent Eagle 2000 fans.
I dont have a fan speed regulator yet. But I was wondering how fast the fans spin when they are connected directly to the PSU. (2000rpm)
I have a Corsair HX 1000W PSU.
I'm not quite sure what you are going for here. If the fans are 2000rpm fans then they should spin about 2000rpm +/- some small marginal. Of course there is not quarantee that they actually run that speed but we cant really guess it either. You need a fan controller to see the exact speed :)

They ususually rate the fans RPM at +-10%, plus you need to account for you 12V rail. If it's 12.5V, then that's another 5% error.
Fan RPM is not at good and consistent as we would all like, it seems their RPM sensors are not exactly the highest of quality
So it could vary between 1700 - 2300.

I know it doesn't apply to this question but, let's not forget that most fan controllers don't supply a full 12V to fans either. I think most are around 11.5V on a full 12V supplied.
