Lenovo Legion Go S: fan and sleep problems, with Steam Deck OLED buying context

Before You Buy

Models in your region

The owner describes a Windows Legion Go S, but the exact CPU, memory, part number and OS image are not given. Lenovo lists several Legion Go S configurations, while the US reference model below is a Z1 Extreme machine with SteamOS, so its specifications should not be treated as proof of the owner's exact configuration.

The owner's fan and heat observations

The owner reports that Beast Mode is quieter than Custom Mode while maintaining the same frame rate, but also says the fan becomes loud after running a small program and can continue when nothing is open. The reported hottest areas are the screen and the section below it; this is an individual use observation, not a measured temperature result.

The owner's strongest handling warning concerns sleep state: the Legion Go S should not be placed in a bag unless it is fully asleep, because the owner says it can become hot enough to fail otherwise. The source does not establish how often this happened, the temperature reached, or whether permanent damage occurred, so buyers should treat it as a practical caution rather than a quantified failure rate.

Windows software needs more attention

The owner preferred AMD software to the tool called Lossless Scaling in Windows use, but reports that games could flash and exit when using Lossless Scaling and does not know the cause. Because the source does not identify that tool's exact version or the affected games, the report cannot show whether the problem is specific to the Legion Go S, Windows, a driver or the individual software setup.

The owner also supplied a command for removing the Windows Web Experience Pack through winget: winget uninstall "windows web experience pack" --accept-source-agreements. This is the owner's stated cleanup step, not a Lenovo recommendation, and removing a Windows component may change related system features; the source does not document the resulting behavior.

Check the exact Legion Go S configuration

Lenovo's Legion Go S family includes Ryzen Z2 Go and Z1 Extreme options, 16GB or 32GB memory, Windows 11 Home or SteamOS, an 8-inch 1920×1200 120Hz IPS display, two USB4 ports and an approximately 730g weight. Since the owner provides no full part number, CPU or memory capacity, those specifications cannot be attached to the reviewed unit without confirmation.

The US Legion Go S reference model is specifically the Z1 Extreme 32GB version with SteamOS, a 1TB SSD, a 55.5Wh battery and two USB4 Type-C ports with DisplayPort. It is useful for checking a US listing, but its SteamOS software and identified hardware mean it does not validate the owner's Windows fan or crash experience.

How the Steam Deck OLED differs

The Steam Deck OLED uses SteamOS 3 and has a 1280×800 display running up to 90Hz, a 50Wh battery, an advertised 3–12 hours of gameplay and an approximate 640g weight. These are family specifications; the post does not provide the owner's game settings or battery results, so they should not be read as a battery-life comparison with the Legion Go S.

Valve divides Deck compatibility into Verified, Playable, Unsupported and Unknown. Playable games may require manual adjustments, while Unknown means the game has not yet been checked; therefore a compatibility badge count is not a count of every game that can run.

Screen and operating-system trade-offs

The owner liked the Legion Go S's large screen and visual experience, but the source does not provide a measured brightness, color result or display size beyond the product family's official 8-inch specification. Buyers comparing screens should therefore use the listed regional specifications rather than treating the owner's visual impression as a measurement.

The owner describes native operating-system support and reports Windows use, while Lenovo's US reference configuration runs SteamOS and the family datasheet lists both Windows 11 Home and SteamOS. Confirming the OS on the exact sales listing matters because the owner's Windows software and sleep observations may not apply to a SteamOS configuration.
