rMBP 13 Early 2015 with Fan speed = 0 rpm while idle

I've noticed my new MacBook Pro 13 Retina Early 2015 (i7 3.1 16GB 1TB) while idle the fan speed is 0 rpm, I've tested this with iStat 5.1, Macs Fan Control 1.2.1 and smcFanControl 2.5 and they all show the fan speed = 0 rpm, if I ramp up the CPU usage by using Geekbench 3 it can get up to 6,200 rpm with a CPU temperature of 62C. I've checked with a co-worker using the same exact computer and his fan is always at 1,200 rpm while idle, is it mine defective?

MacBook Pro (Retina, 13-inch,Early 2015), OS X Yosemite (10.10.3)

Forget third party apps. RunApple Diagnostics.

I did run Apple Diagnostics and everything was fine. I did go to the Apple Store and tried a different OS and it was 0 rpm, then we tried another rMBP 2015 and it was 0 rpm, then conclusion it's a characteristic of the new Laptop to fully turn off the fan while idle, I would assume to conserve battery.

Then there is no reason for concern.

Don't be tempted to use clever third party hacks to override the Mac's design and force the fans to operate abnormally. All that will accomplish is draw in needless environmental contaminants, accelerate wear, and possibly invalidate your Mac's warranty.
