Morning y'all, I hope you're doing alright and can help me.
I own this gaming laptop:
Showcase - RoboMan's Gaming Laptop 2022
CPU Intel Core i5 10500H
GPU RTX 3050 4GB
RAM 16GB (DDR4 2667 MHz)
Storage 256GB SSD + 1TB HDD
Security software installed: Kaspersky Standard and SysHardener.
And since a couple of weeks back I'm experiencing significant FPS drop and overall horrible system functionality from time to time.
Hello
@RoboMan
From what you described in the thread, this is classic
thermal throttling: after one LoL match you’re seeing
CPU ~98°C and
GPU ~87°C, and once throttling kicks in the whole system becomes sluggish until reboot. You also mentioned it
still happens after a clean Windows install, so it’s very unlikely to be an “OS problem.”
Here’s the most practical fix path, in order.
1) Prove it in 2 minutes (so you’re not guessing)
- Install HWiNFO64 and run Sensors only.
- Start a LoL match for 5 to 10 minutes.
- Watch these lines:
- CPU Core Temperature (Max)
- CPU Effective Clock
- Any “Thermal Throttling / PROCHOT / Power Limit” indicators
- GPU Clock and GPU Temperature
If you see clocks drop hard (example: CPU falls near 800 MHz to 1.5 GHz) while temps spike, that’s your smoking gun.
2) Immediate workaround that usually stops the “hell unleashes” moment
This sacrifices a tiny bit of peak performance to keep temps under control, and LoL won’t care much:
- Windows Power Options → Advanced → Processor power management
- Set Maximum processor state = 99% (this disables Intel Turbo Boost on many systems)
- In League settings, cap FPS:
- Set a cap like 120 or 144 instead of “uncapped”
This often drops CPU temps by a lot and prevents the system-wide lag spiral.
3) Fix the root cause: repaste done correctly (your current symptoms scream “bad contact”)
If paste was changed and temps didn’t move, common causes are: uneven mounting pressure, wrong screw order, dried paste, too-thick pads preventing contact, or the heatsink not seating flat.
Do this carefully:
- Remove the heatsink, clean CPU and GPU dies with isopropyl alcohol until shiny.
- Apply a high-quality solution:
- For thin gaming laptops, Honeywell PTM7950 (phase-change pad) is often a huge improvement and more consistent than many pastes.
- If using paste, use something known for laptops (not watery, not old), and apply a small, even amount.
- Check thermal pads:
- If pads are too thick or shifted, the heatsink won’t clamp properly on the CPU die.
- Tighten heatsink screws in the numbered order gradually (half turns in a cross pattern).
If after a correct repaste the CPU still rockets to 98°C in LoL, the next likely culprit is the cooling hardware itself.
4) Make sure MSI’s fan profile is actually helping you
On MSI laptops, you often need MSI Center or Dragon Center features for aggressive cooling.
- Install the official MSI utility for your model and enable any equivalent of Cooler Boost or a max fan / performance profile.
- If your model won’t expose fan control, a cooling pad can still help (especially on thin chassis).
FanControl was also suggested in the thread, but laptop EC support varies, so treat it as “maybe.”
5) If repaste + airflow doesn’t fix it, replace the cooling assembly
If a heatpipe is partially failed or the heatsink is warped, paste changes won’t solve it.
On a thin laptop like the MSI GF63, a
replacement heatsink + fan assembly can be the real “final fix” when temps are stuck near TJmax.
6) Still do these “no downside” settings (they prevent iGPU/power weirdness)
These won’t solve 98°C, but they prevent the game from using the wrong power behavior:
- NVIDIA Control Panel:
- Power management mode: Prefer maximum performance
- Windows Settings → Display → Graphics:
- Set LoL executables to High performance (NVIDIA)
If you want the shortest “do this first” checklist
- Cap LoL FPS to 120 or 144.
- Set Max Processor State to 99% and test.
- Repaste yourself, checking pads and heatsink contact.
- If still 95 to 100°C, replace heatsink/fan assembly.
If you tell me your exact MSI GF63 variant (full model name) and whether you have MSI Center/Dragon Center installed, I can point you to the right fan/performance toggles for that chassis.
