i rebooted, reset SMC, still happening
glad I'm still under warranty and going to bring it in tomorrow, but any insight to this?

You are watching too much HD porn and you're video card is struggling, lol
thats odd, is it just doing that on Chrome???
Maybe a temp sensor somewhere is failing and intermittently sending erroneous readings.
BTW, anyone know if having multiple OS versions cause some issues between firmware and OS?
I would take it back in.so its started doing it again, but whats odd is that powering down and back up stops it
does it on el cap and sierra partitions,
SMC reset, i just reset it again, seems to happen every other week
i wonder if its software- what would you do at this point? just ask for a new fan/logic board ?
still under warranty, i just wonder what the heck is going on if diagnostics say everything is fine, including the fans operability
When the fans kick in, does your Activity Monitor show any sudden changes in activity, such as CPU, or memory?
Do the fans follow increases in actual temps reported by any of various utilities that you could use to show those reported temps?
Do the temps then drop, and the fans slow down?
Or, the fans seem to be unrelated to any temp changes?
And, the fan utility might even report that the fans are at zero, even though running at speed, which might indicate a faulty fan, or a bad sensor.
The outside or case temperature is not at issue (and wouldn't affect the fan anyway)
Also, not asking about what you are doing at the time.
I just question if your Mac (without any input from you) is doing anything to make the fans kick up.
The Activity Monitor will tell you part of that.
The other is a temp sensor utility that shows you both fan speed, and temps reported by the various sensors.
Is there a spike in the temps reported at the same time that the fans kick up?
Or, nothing significant?
When the fans do kick up, do they only slightly speed up (say to 2500 rpm), or full speed (most would be 5 to 6000 rpm, more or less)
You are correct, of course. 1 degree up would not cause a fan to kick up.
But I am also guessing that you have already tried to watch the temps, just to see if there is any correlation between the fan, and higher temps. And of course, I am sure that you realize that you can't tell the temperature by touch, particularly for a temp spike that may only last long enough for the fan to kick up. The fan kicks up, with more cooling air, and the temp drops right back down, followed by the fan slowing to idle.
I'm sure that you have already checked all that.
Have you tried the built-in Diagnostics test, taking a few of minutes to run that test at the time the fan gets annoying?
Can you try killing the applications one at a time, waiting a while in between and see if the fan shut/slow down? I would start with Outlook if you have that running. It connects looking for mail, etc. on a periodic basis.
