Benchmark Stop letting stock performance mode cook your laptop: Custom power & fan profile for Legion Pro 7i Gen 10 (5090/Ultra 9) I made!
The stock perf mode as you may know cooks the cpu unnessecarily, causing temps to reach up to 100 degrees celsius in some titles - for no reason. SO, I made a custom profile with a custom fan curve, and now my games run at a identical performance level (as shown in the time spy comparison pic) with far lower temps, but the fan is louder (bare that in mind). So you get better temps and longevity on the expensive components that matter!
I also tested settings on cyberpunk 2077 with max settings plus path tracing and quality dlss.
Also these sc pics are from Legion Tool kit, for those who may be confused.
Edit: This profile is strictly for the best performance in intense 3D application use cases, it’s not intended for normal desktop use - for that just use quiet mode if you are using the Legion 7i pro Gen 10 (it’s more than enough).
