I have several other Lenovo SSD systems and there are no issues with the fans. The fan on this is the loudest of any system (including non SSD) that I have had and it stays on.It also does not help when you ship via Canada Post and there is no fragile sticker on it.  There was nothing on the box or label to differentiated this box from a box with a brick in it.The order was also shipped without the keyboard, mouse, and WIFI USB as advertised. Seller did not respond to request for refund. Also had no windows license key or sticker, which even refurb should have.
