Model Name: AN515-54-79EL

Spec

gpu:1660 ti 6gb

cpu:i7-9750h

system: Windows 10 Home

Hi everyone,
I have bought this computer for ca 2 years now and under the usage I have constantly changed the thermal paste on the cpu and gpu to get a better temperature. But today, I realized that changing the thermal paste, for cpu and gpu, does not decrease the temperature anymore and I got two assumptions about why it does not work longer. Either is because my thermal paste, that used for gpu and cpu, gets old and bad or the thermal paste for the copper pipes has been too old. I have already ordered a new thermal paste for gpu and cpu. But in case it does not work, I want to ask if there is anything that can replace the thermal paste for copper pipes? And if there is, do you guys have any recommendations on the brands that I can use? Thank you!


The pink stuffs are the thermal paste for copper pipes.

    Those pink pastes are for vram and they can work with large gap than the normal thermal paste. It is hard to find that exact same paste. There is one called k5-pro, it works the same as the pink paste.

    Unfortunately, I could not find this in my country. However, are there any roles when I applied this kind of thermal paste? Like not too much or too little? I could not find anything about how to change thermal paste for copper pipes.

    Look "DS001" the thermal paste is not the only thing that reduces heat it acts as a shield, btw, you can also use thermal pads but with pads you have to be very careful as if you use too thinner pads the pad won't make contact with your heatshield copper pads when they are fully screed down and it will be useless and turn your system off from overheating. Just as a suggestion, I've been using Thermal Grizzly for a while now and haven't had any problems and also I've been using their new Kryonaut Extreme which is even better, so use that and apply the paste with the "Pea Dot" method, also I've been using a tablet cooler with some known older laptops that overheat and together with the Thermal Grizzly Kryonaut Extreme and a tablet cooler the heatshield for the CPU and GPU works perfectly, the copper does not go off its not like a used by date for food items =)

    Thanks! I actually found few pads. I have few questions more. Hope you can help me with these too. In the picture above, you see few greyish pads. Can I also change these pads too? I assume these are not that good either since it came from manufacturing. I have also looked through different posts and I assume I should not buy pads that are thicker 2 mm, because lot of posts are saying 0.5 to 1.5 mm. Is it correct?

    The best pads for replacement will be around 1 to 1.5mm, thicker than this will make pads squished out and the heat transfer will be worse.
