Legion 7i Gen 6
i7-11800H - 45W
RTX 3070 - 140W
The laptop was actually unboxed by a friend an year ago, he used about 60 battery cycles. Then I bought it from him.
GPU was reaching 80-81 when he tested.
It's been 5 months since I have been using this laptop and I have noticed a pattern. The thermal throttling didn't just suddenly appear but it gradually occurred. A few weeks everything was normal, then I noticed GPU went to 86, then a few weeks later I was playing Counter Strike 2 and noticed my CPU was going near 95 and it throttled and limited temps to 70s.
I downloaded ThrottleStop and limited CPU at 40 TDP. This helped me for about a month.
So about 3 weeks ago I noticed GPU going to 88 Celsius, GPU clock dropping from 1800 MHz to 1100 MHz, GPU power dropped to 70W.
I panicked and closed my game. Got the thermal paste changed (Thermal Grizzly Kryonaut). Unfortunately nothing changed, the temps were still same like nothing had changed.
I lowered the game settings to lowest (around 50% GPU usage) still the GPU power drops to 70W. But GPU temp max goes 86 (throttle limit), GPU clock stays around 1500-1800 MHz. This is really weird.
I must tell GPU TDP always dropped very quickly, since the start, stayed 120-140W for a few minutes and then dropped to 100W where it stayed for long, but this was initial months and now it just easily drops to 60-80W.
I know I had to get PTM 7950 Thermal Pad, but I couldn't find it in my country and Kryonaut at least should have changed the temp pattern in worse way if not good. But it's like it didn't matter.
I believe my laptop is all clean software wise and everything is updated, drivers bios etc.
It was winter, so ambient temperature haven't been an issue, I use it on a cooling pad, I also opened it and cleaned it twice before changing thermal paste, so dust wasn't an issue.
When I turn on the laptop, temps are in 30s. 50s when browsing. Drops back quickly after closing game.
