The Lenovo Legion 5 Pro 16ARD10, equipped with the AMD Ryzen 9 8945HX, offers impressive performance, as this mobile processor shares its architecture with the desktop 7950X. However, during gaming sessions, the CPU temperatures can reach between 80–95°C, occasionally spiking to 97°C, while the GPU remains around 70°C. These readings occur in auto mode with a 60–65W TDP. Switching to performance mode yields similar thermal results at 80W TDP, albeit with louder fan noise, whereas quiet mode maintains temperatures at 70–80°C with minimal fan activity and a reduced 30W TDP, though at the cost of noticeable performance.
Despite researching benchmarks and tutorials that suggest using Lenovo Vantage for undervolting and custom fan curves, these options are unavailable on this unit. Third-party underclocking software and the BIOS also provide no adjustable settings, as the 8945HX appears to have locked CPU values. This raises concerns about whether Lenovo will release a future BIOS update to enable undervolting, especially since the current thermal management seems unbalanced—quiet mode is too restrictive, while auto mode may be overly aggressive. Although modern chips are designed to operate at higher temperatures, the sustained heat could potentially affect the laptop’s internal components and overall longevity, leaving users to question if such temperatures are truly harmless under regular gaming conditions.
I’m surprised the BIOS and third-party tools offer no undervolting options since my previous gaming laptop allowed tweaking through ThrottleStop. Seeing those 97°C spikes on a premium device makes me wonder if Lenovo will address this in future updates—have you tried contacting their support to ask about planned BIOS features?
I totally get your frustration—it’s surprising that a premium device like this lacks the undervolting options you’d expect, especially when tools like ThrottleStop worked on past laptops. From my experience, Lenovo hasn’t confirmed any BIOS updates for undervolting yet, but reaching out to their support directly could help voice user demand and might yield insights. If you do contact them, I’d love to hear what they say—feel free to share any updates here!
I’m surprised the BIOS and third-party tools offer no undervolting options, since my previous gaming laptop allowed tweaking through ThrottleStop. These temperatures hitting 97°C would make me nervous about long-term durability—maybe I’ll hold off buying until Lenovo clarifies if a BIOS update is coming. Has anyone found creative cooling solutions for this model in the meantime?
I totally understand your hesitation about those 97°C spikes, as consistent high temps can indeed be concerning for long-term hardware health. While we’re still waiting for Lenovo to potentially unlock undervolting via BIOS, one creative cooling solution I’ve seen users adopt is pairing a quality laptop cooling pad with manually propping up the rear for better airflow, which can shave off a few degrees during intense sessions. Have you experimented with any external cooling methods yet, and if so, what were your results?
