Question Black Screen issue after replacing the fans on my laptop ?

[romromillys]

Hi Everyone,

Laptop model: Asus TUF Gaming FX705DT (2019)
AMD Ryzen 7
Windows 10 Home, 64-bit

Super Black screen problems started occurring on my laptop after I replaced the fans due to grinding noise. After reassembly, the laptop boots fine, but shortly after logging in, the screen goes black https://blackscreen.onl/ intermittently.

Here are some additional details:

• CPU fan reaches 4000 RPM.
• GPU fan stays around 690 RPM.
• The laptop heats up quickly to 74°C

Could this be related to improper fan installation, thermal paste issues, or something else? I would appreciate any troubleshooting tips or suggestions to resolve this.
Thanks in advance for your help!
