Question SP120 Led Wonky performance

[ron2456]

I recently bought a sp120 red led as a front intake fan and its rpm is kinda jittery.
On initial startup it shoots up to 1650 then after sometime it drops to 1480 and increases to 1550 and then drops back again and keeps repeating this.
I also have a Coolermaster fan but that isn't doing this, it stays stable at 1890-1900 all the time.
What could be the issue here? Is the fan faulty?

The speed in Smart Fan function in Bios is already set at Full Speed. Also one strange thing is that on Corsair's website its mentioned as 1650rpm whereas on the front of the box its 1500rpm and on the back its mentioned as 1550rpm.

After recent forum updates getting help on toms has been pretty tough. Responses come pretty late than before.

I appreciate that but bumping the thread or posting "Anyone?" isn't going to elicit replies any faster ---- it just makes the thread longer for no good reason.
