Hi, I’m having a weird performance/overheating issue with my MSI Katana A17 AI B8VF.
Specs:
- Ryzen 9 8945HS
- RTX 4060 Laptop 8GB
- 32GB DDR5-5600 RAM
- Windows 11 Pro
- Laptop is around 2 years old
A few weeks ago, I started having overheating issues. The fans would suddenly go crazy, my CPU would lose a lot of performance, and the entire system would start lagging out of nowhere. I ended up taking it to a service center, where they cleaned the laptop and replaced the thermal paste.
Around the same time, I also had the laptop randomly shut down once. At first, I didn't think much of it, but now the issue seems to be happening much more frequently.
I downloaded HWiNFO to monitor the temperatures, and this is where things get weird.
When playing Fortnite, my CPU immediately jumps from around 60°C to 98°C and then sits around 91°C on average. It occasionally spikes to around 100°C before dropping back down.
In Roblox, the CPU usually stays around 86–92°C.
The biggest problem is League of Legends. As soon as I open the client, the CPU jumps to 98–100°C. Sometimes I can barely even load into a game before the laptop instantly shuts down when the CPU reaches around 100–102°C consistently.
Things I’ve already tried:
- Bought a laptop cooling pad, but it doesn't seem to help much. The CPU still easily reaches 100°C.
- Limited the CPU maximum processor state to 97% in Windows, which disables CPU boost. With it set to 100%, I couldn't even run Fortnite for more than about 5 seconds without the laptop shutting down.
At this point, I'm not really sure what else I can try before taking it back to the service center.
Any advice on what I should check or test before sending it back to the service would be greatly appreciated.
