I am actually scared 'cause I never repasted anything and it was my first time opening a laptop this way.

    Also do you think the factory paste you see in the picture is dried out? If so, could that be the reason of my CPU temps getting higher?
    I would recommend Thermal Grizzly Kryonaut or Arctic MX-4. Any other name brand should work just fine though. As for the vrms, you can either use K5pro or thermal pads. K5pro is easier to use but not so easy to find depending on where you live. If you're going to use thermal pads, you have to measure the gaps between the heatsink and the components and buy the pads accordingly.

    The paste looks fine as far as I can see, but don't mix two different types of paste like that. Clean it all up really well then apply new paste. If you decide to remove that protective plastic thing, be careful with the passive components around the die when cleaning. You can easily knock them off the substrate.

    Thanks again! I ordered both the Arctic MX-4 and the K5 pro. Will update my temps after repasting (but I won't remove the plastic thing or use thermal pads). Have one last question though. I was checking some youtube videos and saw that many use the same paste for GPU/CPU and the vrms. Looking at the factory paste on my laptop looks like they also used the same kind of paste for everything. Do you think I can use the Arctic MX-4 on the vrms too? Or is the K5 pro really that better?

    Regular paste on the vrms is not really ideal because usually there's a gap between the heatsink and the components. Regular paste isn't thick enough to fill that gap without dripping out over time. k5pro is more like a jello kind of thing.
    From the factory it usually comes with k5pro on the vrms and regular paste on the dies. Don't even think about using k5pro on the cpu and gpu.

    First off, thanks a lot for the help! I would have never take the courage to repaste without your advices.

    Repasting worked pretty well. Gotta be honest, I did it twice. First time I wasn't satisfied with the result, as I was still getting my CPU up to 93°C with Forza Horizon 4. So I repasted again putting a bit more paste on both CPU and GPU. Now my CPU never goes over 81°C, it usually stays on mid 70s, so it's a huge -15°C difference. My GPU temp also decreased by 5-6 degrees, usually staying at low/mid 70s up to max 78°C on most demanding games. This is with CPU undervolt -125mv and a light GPU overclock (+215, +200). I also noticed what's being said in the first post. When the GPU temp increases CPU temps increase too. I forgot to say that my room temperature is 30°C, sometimes even a bit more (no AC), so I hope to get lower temps in the next months.

    I am actually surprised repasting worked. Have one last question now: how often should I repaste? The Arctic MX-4 package says it can last for 8 years (but I doubt...). What about the k5 pro? Is there any negative effect of repasting too many times?

    Btw I also noticed something weird on my CPU that I never saw on any other CPU (on youtube videos). There is this green small part you can see in the picture. I don't know what's that but it doesn't seem normal to me.

    Good to hear that! Many times the problem is just bad heatsink seating. If it overheats right after repasting, just retry a couple of times and it might solve the problem.

    The paste should last at least 2-3 years. There's no negative effect of doing it too often, but don't worry about it until you start to notice the temperatures rise again.

    That green stripe is just the substrate. They probably use that same plastic thing for different chips with different die sizes. That's normal.

I ended up wrapping a cotton bud around a wipe and just gently wetting / rubbing the paste away. Anywhere that wouldn't budge I wrapped a wipe around a very very thin flathead screw driver only to dislodge dirt and not clean.


    Unfortunetly the laptop is all back together so I can't show photos however I used the below image for pad sizes and fitting

    Hi,
    i decided to repaste my gl502vmk, i chose the arctic mx5 as the thermal paste but i am confused about the thermal pads. since arctic thermal pads 50x50x0.5 mm is approx 20$ in local currency so is one of those enough for all the VRMs?
    Please let me know so that i can proceed to order them

    My computer is an GL703GM strix scar edition. It has an i7-8750H and Gtx1060. It's a good laptop unfortunately i keep getting blue screens and it keeps appearing unless i put it on high peformance mode. Could someone help me out here, i'm not sure what to do and it's getting annoying.
