Long ventilated laptop after shutdown Windows

Laptop Lenovo Ideapad Y50-70 (Core i7-4720HQ 4-core, 8Gb RAM, Geforce 960M, the non-removable battery, 9ECN43WW BIOS Version(V3.03) 2015)
Notebook Acer Travelmate 5760ZG (Pentium 2Core, 4Gb RAM, Geforce 630M, battery removable, BIOS Insyde EFI V1.8, 2011)
On Lenovo is not quick to load Win10 (an old Acer with the same Windows image and set of programs runs for 30 seconds until the desktop), and after the certification of the work and gacinia screen a minute and a half or two blowing air! When you restart it it does. Acer turns off immediately (whether there is battery or not)
At startup only the differences with the drivers from Lenovo's more of them.
Windows s on both laptops, not cluttered.
Is it possible to do something with Lenovo? Guess that's setting the motherboard to blow air after each shutdown. But it is strange to wait for two minutes until the fan dataregister the air. Speedfan shows a temperature of 35-40 idle.
