Have you tried the 4GB patch?
Run OpenHardwareMonitor.org in background and watch the clocks in plot.

1) CPU / GPU repaste (with a good paste such as Kryonaut).
2) Check the ventilation.
3) Use ThrottleStop software to properly manage CPU limits and prevent it from overheating (ie Undervolt).

Yes you have to be very careful. If you can't do it yourself, ask a professional.
It should also get all the dust out of the fan.
With Grizzly KRYONAUT paste you lower the temperature by 8 or 10° at full load ...
I have checked it on several of my laptop.
It's the same for the ThrottleStop software, it's reserved for advanced users.
Personally I have Undervolt the CPU of 180mv, and 90mv for the cache.
I gained 3° Celsius again.
So, total -13°
now with Cinebench I am never throttle-PROCHOT again, it remains below 88° for 4.5 Ghz, 16 threads full charged. (MSI Leopard laptop).
Before all that, the PROCHOT system limited the frequency to 3.2Ghz or lower because of the temperature. This is why I am bringing up this subject here.
Repaste example for your laptop :
below my laptop, there are a lot of components to colded ...
On yours it's much easier.

Yes this T470 seems easy also for beginners.
My T520 temps are 40-69°C so no need to renew the paste - get all infos in the Thinkpad forums with good how-to's

OMG - MSI must have had to use up their toothpaste
On a laptop gamer it's really nonsense

No, I'm running a G29
