MacBook Pro 15" Retina 2015 Fan Speed inconsistent

Hi guys,

Perhaps someone could enlighten me..

I have Macs Fan Control Installed on my 2015 MacBook Pro 15" Retina.

Serial Number C02RW08NG8WQ.

Macs Fan Control Version 1.5.8.1.

This is my problem: When set to full blast, I was expecting the fan rpm to sit at 6200rpm for both fans, however, my left fan is running at 6156, and my right fan maxed out at 5700rpm.

Is there a reason for this? or am I being paranoid.

My 2012 MacBook Pro 15" pre-unibody always synced both fans to 6200rpm on full blast!

Thanks in Advance.
