Lenovo Legion Help

[DanyRinolds]

I am pretty useless when it comes to computers and I need some help. My computer,a Lenovo Legion Y545 PG0, has been running fine for some time now. But now, anytime I play a game it lags terribly and the computer gets pretty warm. Some games it takes time for this to happen, but Fortnite is definetly the worst. Within a minute or two of playing the game starts to look like a ♥♥♥♥♥♥ claymataion. Anyone have any suggestions of what to do?

Check that the air intake, usually found on bottom side of laptop, it'd be better if you can open the bottom panel to check for dust bunnies. Below is a pic of my Legion 5 Pro (circa 2021 I believe), note the two fans, the whole cooling assembly was replaced by the tech who'd come to check on my CPU (R7 5800H) and CPU (RTX 3070 140W) were overheating (bought mine from used from another in a garage section of a local forum).

I now do maintenance work myself by opening the bottom cover and cleaning off whatever dust I find, especially on the fans, and the intake vents on the back cover. Make sure that Lenovo allows for mods and whatnot (like opening the back cover) which I did, upgraded my SSDs to 2x 2TB nVMe M.2 SSDs, and upped RAM from 16GB to 32GB.

Monitor the CPU/GPU Temps and ensure it's not thermal throttling.
