Top critical review
on 23 April 2014
On paper the spec is brilliant, I bought a used one from Amazon but when I turned it on the laptop fans went to 100% instantly (really really really loud) and never dropped (even on idle).
When I searched for Lenovo yoga fan issues there was a 98 page forum thread on the Lenovo website, seems this issue has been going since 2012.
Maybe you'll have better luck than with your purchase but fair warning, your fan may well have issues.
