A look Inside
Peering inside the Lenovo Legion 5 Pro reveals a fairly standard layout, with plenty of heat shielding and some huge heatpipes all around. The two fans at either corner feature a large number of fine blades, helping the cooling system stay quiet under load, while still moving a fair amount of air.
We find a 80 Wh battery installed on the bottom edge of the internals, while the DDR5 system memory is installed in the middle, above the battery, under a black metal protective square. It's worth noting that although this model only has 16 GB of DDR5, comprised of two 8 GB modules.
There are two M.2 drive locations, on either side of the board. These also feature metal covers over them, as is becoming fairly standard these days. All this heat shielding should help evenly disperse system heat, making the fans have less of a job to do under general usage models.
