Thinkpad P40 Yoga Pulsing Fan

Hi there,

I received my Thinkpad P40 Yoga roughly 6 months ago and have not had many issues, however, for the past few weeks I've noticed my fan at times pulses with a very annoying sound.  At times when my fan runs, it sounds like it is pulsing.  Sometimes it's constant, while other times it pulses and I'm not entirely sure why.  I looked around and read a few posts stating that sometimes a BIOS update is required.  I got software from the Lenovo website to automatically update it, but the sound remains.  Any help would be greatly appreciated, thanks!
