Acer Nitro 5 up to 98 degrees?

I've asked questions about my laptop and games (Fortnite, Sims 4) a few times in the past few days and need help again.

As soon as I play Fortnite (at medium settings, 60 FPS), the CPU temperature goes up to 98 degrees and stays between 90 and 98 degrees (I have NitroSense open all the time).

I know, some will now say "Laptops are not suitable for this, get a desktop PC", but these gaming laptops are not completely free and I want to be mobile, I also have back problems and can't sit at the table in front of my PC forever sit.
Does anyone know a solution or cause? Possibly. Renewal of thermal paste or something?

My data:

WD Blue 3D NAND 500GB SATA-SSD M.2 2280 6GB / s (on which the games are installed)

1000 GB SATA hard drive
8th generation Intel Core I5-8300H Coffee Lake architecture

@ 2.3GHz / 4.0GHz Boost, 14Nm manufacturing, CoolBoost Technology, HyperThreading and UHD 630 graphics

Nvidia GeForce GTX 1050 4GB GDDR5
16 GB DDR4 memory

I would clean the PC and renew the WLP as you said. 90-98 ° C is really too much.

I think it's best to get a "blow plate", a pad with fans especially for notebooks for additional cooling.

That with the wlp lass ma prefer, that is tight in the boxes and not easy to tinker with.

I wouldn't tinker with it myself. A friend of my parents does something like this professionally, maybe I would contact him then. I also want to get a USB cooling thing, but some write that it only gets 5 degrees cooler.

Then ask them how they measured it. In addition, 5 ° at 98 ° is already a lot.
