asus rog GL704 gpu+ cpu fan replacement

[solo12345]

Hello,
I just bought a used RoG laptop, a GL704_715 and the gpu fan has issues spinning.
I won't bother with temporary fix and will change both cpu and gpu fans.

Now, the only kit I found comes from China.

Question:

Since I will dismantle the laptop, I wonder if there are better fan alternatives that are really effective to cool the laptop down.

It's a laptop, I want it to be transportable so fans have to be inside the case.

I will take a good thermal paste as well, since I don't think liquid metal will do.
Too many components to reapply the paste on.

Thanks!
