Kaze Master Pro not showing correct rpm?

[Krokben]

Hi!

I recently bought a Kaze Master Pro as the title implies, and I'm using it with six Gentle Typhoon 1850s. Everything is working fine (I think), and I can control the speeds of the fans. However, at the max rpm setting with the knobs, the display only shows 1650-1680 rpm, no matter what channel I try to max out.

Help please

A possible reason: virtually all Scythe fans have a tolerance in rpm of + / - 10% which would mean that a 1850 rpm Typhoon could have any max rpm between 1665 and 2035 rpm.

The tolerance is also printed on the package.

Ah alright. Actually didn't say anything about the tolerances on the packages I recieved, but now I know! Cheers

Well AFAIK it is written on any retail package.

See: http://www.overclockingstation.de/ph...ed-Package.jpg

In the field where the rpm is shown there is +/- 10%. But a retail shop could sell these fans as bulk and remove the package.
