[SOLVED] Lenovo laptop underperforming

[palpitation-feeling]

Hello,
my 6 month old laptop started underperforming recently. Most likely its bc of thermal throttling but i'm not sure. I've done a furmark bench just when i bought it. The performance was stable and around 70 fps. Now my gpu after it heats up to around 76 celsius and then dramaticaly drops its performance (from 70 to 23FPS) but its usage remain the same (MHz drops too). The performance wont come back unless I restart the laptop. I've tried changing the power plan, installing newer drivers, and restoring factory settings but it didnt help. I've noticed it after i tried to play phasmopobia. Throughout first 10minutes it was fine, high framerate and stuff, but then the significant drop in performance happens and makes the game unplayable. On the pics im sending the first one is from the first week after i bought the laptop (stable 70FPS for 16mintues straight) and the second one shows how it performs now(stable 70FPS for 45 seconds 🙁 and then it drops to 16-30 untill i restart)

Might be overheating processor, it shares same heatsink usually meaning your gpu gets higher temps. Download intel XTU and run the stress test , if you see "temperature throttling" for the cpu then that is the issue and you need to change thermal paste inside of the laptop. This in combination of undervolting usually fixes the issue.

If you dont want to change thermal paste you can try undervolting before that but in the end that might not solve it completely, start with -75mv and go from there on ,
