This is a snippet taken from the full review of the IdeaPad S940. You can read the entire review here.
Since this is a flagship laptop, it should come with some of the best specs you can get in a machine of its caliber. Luckily, Lenovo comes through with the IdeaPad S940. Under the hood, my review unit came with an 8th-generation Intel Core i7 processor with 16GB of RAM and 512GB of SSD storage. You can also configure the computer with 8GB of RAM and either 256GB of 1TB of SSD storage. There’s also an option for a Core i5, but I think it’s worth at least upgrading to the i7.
Performance, as you’d expect, is great. Light tasks fly on this laptop, and heavier workloads are also easily managed thanks to the 16GB of RAM. You only get Intel UHD 620 graphics so you can’t necessarily do any heavy gaming or 8K video editing, but considering the size and form factor of the S940, you probably won’t buy it to do this anyway.
It’s worth noting, though, the S940 does run pretty warm. During my testing, I noticed it got a bit warmer than I was expecting. I don’t have a thermometer to measure exactly how hot it got, but I will say, it got warm enough that I questioned what else could be running besides a couple of Chrome windows. Notably, I didn’t have anything else running, therefore confirming that this laptop simply runs a bit warmer than most typical machines.
I was curious, though. For a while, I actually thought the IdeaPad S940 was fanless. I didn’t hear anything when the laptop got warm, so I thought maybe Lenovo was doing some sort of internal cooling that wasn’t working. so I asked Lenovo who told me they did include fans with the S940. To kick them up a notch, you can go into the pre-installed Lenovo Vantage app and click on “Intelligent Cooling” to benefit both the cooling property and battery life of the laptop. I switched it on, but it didn’t make very much of a difference.
