G751jy Temperature almost the same after changing thermal paste

Well, that hard to say just looking at the photo. I reported my experience of when I used pads and I had CPU temps issue (mostly on one specific core), and I suggested you to try with thermal paste only.
I know that is a tedious and expensive process, but I think only thing you can do now is to re-assemble it with thermal paste, at least on the little MOSFETs (ones cirled in red, that have a good contact).

Even in my case CPU contact looked good at the view, but I solved my problem in that way.

I did some tests with the pads now and I think you're 100% right. Unfortunately, I ran out of paste , so I have to wait for a new one before trying it out.. Thank you though, should've listened to you from the start.
Guess I wanted to use the pads for something since I paid for them already.

On the one hand, I know this is a bit tedious and it's not great to be stuck waiting for a new thermal paste, I have been through this.
On the other hand, I'm happy that you're on the way to solve your problem (and happy because I didn't let you disassemble it again for nothing )
Let us know how it ends up.

About the pads, mine are currently gathering dust.

In the pictures, it looks like you applied the paste perfectly. Anyway, Asus are using only thermal paste on their last products and are considering transition to Liquid Metal.

The closet thermal paste I found for the chips installed on a factory laptop thermal paste was K5 Pro thermal paste. The density of thermal paste for CPU and GPU is to thin for chips.

When you installed thermal pads, it also increased the heat sink distance between the GPU and CPU. Did you use copper shims on CPU and GPU to compensate for that distance?

On laptops, because the clearance between the heat sink for the GPU and CPU is so tight K5 Pro thermal paste with its putty like density will fill in the gap for the chips. Twenty grams of K5 Pro thermal paste is more than enough for one laptop.

Use a syringe to apply the K5 Pro thermal paste (elevates a mess, not required) to heat sink for chips. Mix the K5 Pro for better density before applying or putting in syringe (not required). Just like salad dressing or paint, thermal paste separates somewhat (I could be wrong).
