Question 2070 RTX Fans running different RPM's - Help

Hey.

I did some benchmarking, and noticed that my fans isnt running the same speed/rpm under load.

In GPU-Z & Afterburner, it shows Fan 1 to run at 2384 RPM and Fan 2 to run at 1984 RPM, is that suppose to be like that? Fan speed was at 71% under that current load.
See GPU-Z Screenshot: http://gpuz.techpowerup.com/19/04/23/hmf.png

When it's idling and with a fan speed of 43% it runs the same RPM, within 5 rpm difference.
When it's on load and with a manuel fan speed of 100% it also runs very oddly different RPM's, by ALOT. Fan 1 3310 RPM and Fan 2 1787 RPM.
See GPU-Z Screenshot: http://gpuz.techpowerup.com/19/04/23/mgp.png

I've got a Asus Strix 2070 RTX Tripple Fan. I dont know why a 3rd fan isnt showing, dont know if you know why that is.

Anyway, hope you can help.

Best regards

if your temps are fine I wouldn't worry about it, maybe the fan over the GPU is set to run at a higher RPM as that is where the heat is centralized.
Yeah that could be a thing. It just made me wonder, if there is a "Fan 2" why isn't there a "Fan 3" since there is a total of 3 fans on the card.
And also, it would be nice to be able to control all of the fans (if what you said is correct). Because as soon as my card hits 55-60c it clocks down 1 or 2 steps on the core clock, hehe.
