    ROG GU501GM Thermal Paste Replacement

    Hello! I finally grew the guts to do a repaste on my machine. I used Kryonaut and Arctic Thermal Pads.

    The stock paste on this is complete garbage. It was hardened and seemed to me that way too much was applied in the factory.

    After cleaning up, I added 1.5mm Arctic Thermal Pads to the VRAM.

    The results are great so far! Off the bat I'm noticing up to -10 degrees differences in idle temps.

    I also ran a stress test in CPU-Z before and after and here is a snapshot of the results (in HWMonitor)

    If you're planning on doing this, I totally recommend it. Here is a great YouTube video that helped out a ton.

    Update

    So, the results were good, especially on the cpu side of things, but now the GPU is pretty much back to normal temps I was seeing with the stock paste (after only one day). I have a feeling it could be the thermal pads were a bit too thick (1.5mm) on the VRAM which may be causing the heat sink to have limited contact with the GPU. I'm going to remove the pads and apply Kryonaut to the VRAM instead. I'll report back tomorrow with my results.

    Thermal Pads not always better than paste for ROG GU501GM

    Ok! So I got my hands on some Hydronaut (couldn't find any Kryonaut) thermal paste and reapplied. The numbers are looking great! I was correct in my assumption that the thermal pads were not allowing the heat sink to properly sit on the GPU section on the laptop. That's probably why ASUS shipped this laptop with thermal paste instead of pads to begin with (I should have known).

    In testing The Witcher 3 on high-ultra settings, before the repaste I was hitting 76-78 degrees. Now, 69-70!

    I also noticed that someone else on this forum had a similar experience with their ROG laptop, check out the post by user Dimonic here.

    All in all, I'd say that applying thermal paste instead of thermal pads to the GPU VRAM and vrm of the CPU has made a huge difference for me!

    Just a thanks message

    Hey thanks for sharing, I was considering repaste too and now I am going to do it these days

    Just one thing to ask, are the CPU/GPU main die on a horizontal surface with the VRMs,
    or has the heat sink/pipes even out the height difference?

    I might share my feedback too after I'm done
