Hi everyone!
I own a Lenovo Legion Pro 5 16ARX8 with a Ryzen 9 7945HX and RTX 4070, purchased in October 2025.
Recently, I started monitoring my CPU temperatures while gaming and noticed some surprisingly high readings. I'd really appreciate hearing from other Legion owners, especially anyone with the same processor.
Here's what I've observed:
Balanced mode: HWiNFO showed CPU (Tctl/Tdie) averaging around 100°C during a roughly 16-minute gaming session, with peaks of 103°C. CPU package power averaged approximately 52 W.
Performance mode: Core Temp showed CPU Tdie reaching 101°C, with CCD temperature readings peaking at 103–104°C. Individual core temperatures stayed below 100°C.
Custom mode with a 90°C CPU limit: Temperatures stayed around 90–91°C, but I experienced noticeable lag after playing for a while. Switching to Performance mode immediately resolved the lag.
Interestingly, not every game causes these temperatures. Elden Ring, for example, ran noticeably cooler.
The laptop is elevated for better airflow, and I haven't experienced thermal shutdowns or other obvious hardware problems.
I contacted Lenovo support. They remotely ran a CPU stress test using Lenovo Diagnostics Evolution, but the CPU only reached around 91–92°C during that test. That seems quite different from what happens during actual gaming.
I've also received conflicting opinions. One technician suggested that temperatures above 100°C might indicate a cooling issue, while another said these temperatures are normal for a powerful gaming laptop.
AMD lists 100°C as the maximum operating temperature for the Ryzen 9 7945HX, which is why I'm uncertain about the readings above that figure.
My questions:
Does anyone with the same CPU or Legion model experience similar sustained temperatures while gaming?
Are these readings expected behavior, or could they suggest an issue with the cooling system or thermal interface?
Has anyone had Lenovo inspect or repair their laptop for similar temperatures? Did it make a difference?
The laptop is still under warranty, but I'd prefer to understand whether there's actually a problem before arranging a repair.
Thanks in advance for any advice or personal experiences!
