I have an acer aspire a315 laptop that uses Ryzen 5 2500u, sometimes I use it to play games, when I play games on a battery (not on charge) I get around 30 fps, and I don't mind it, when I play games while charging , the fps increases, it is better, but the heat is felt immediately. Well I prefer to play at 30 fps but not hot, rather than high fps but the CPU feels hot. is there a safe way to limit the cpu temperature when charged. Sorry if my english is bad.
I suggest the power saver power plan, it tends to keep a CPU running cooler and only runs when demand is higher
that or find a more powerful PSU for the machine
I've tried it, but like nothing has happened
There's no reason to worry, as all the components in that laptop are built to tolerate very high temperatures. If it really makes you uncomfortable, you can use a laptop cooling mat.
When I play a game while charging, the temperature is 75-77 Celsius, is it safe? And it's best how long I use a laptop if the temperature is stable around that ?
That's fine, the CPU/GPU is rated for 95*C, and if it's topping out under 80*C while gaming and charging, that's nothing to worry about, you can use it as long as you'd like.
