You say this is your 3rd Yoga 2 Pro?
With regard to the fans, has it always been the case with this particular one or all of the ones you have had?
Did this begin day one, or did it develop over time? If it developed, perhaps there is some Windows update that has affected power management?
What kind of system temps are you seeing?

Mark I believe my fan issues may have stemmed from the fan becoming temporarily unbalanced causing a slight grinding noise followed by some heavy speed cycling. My guess is that the system noticed the unbalance and went into some sort of protection mode to prevent overheating or perhaps to force the fan to rebalance.
Seems to have worked as fan has not grinded since. However it does still go into some speed cycling for about 2 minutes occasionally (like an engine revving). This may be a maintenance routine to keep the fan balanced. Who knows?

Are you running the Lenovo preload? What mode do you have energy management set to? (And does changing it affect your fan?)
Did it do this since day 1, or after some Windows updates? Yoga 2 Pro has been out a while and we are just starting to hear these fan concerns, so I'm wondering if something has changed?
Could you try some software to check CPU temps? Also, if you start the system cold, does this happen right away or after it heats up?

Ok So my buddy has one, and I have two (one is being sent back)
His at 39C, the fan is off
My replacement (newest one) is at 36C and I could hear the fan. This one also has really off colors. My current and replacement both DO NOT have the bios update. I chose not to do it because the very first Y2P that I already sent back had issues with screen flickering at low brightness settings.
CPU ussage is 2-6% I'm not even touching it.
The 2nd one that Im sending back (I'm probably going to keep this one instead of the newest one because of the really off color) is quiet at 37C
This really sucks. I want to like this laptop so bad. I keep gettiing tempted to buy something else, but there isn't anything I like!

I saw your other thread on the color.
I'm still not clear why you didn't apply the BIOS and Power manager updates? Most people reported success with them in the main "Yellow" thread.
It may take a few days, but we'll look into the fans.
