    I tried this paste before. This is by far the worst thermal paste I used in my life.

    There are German sellers on ebay that sell ICD and ship to Turkey. Give one of them a shot.

    That paste is electrically conductive right? Anyways I'll look at eBay.

    No sir ICDiamond is non-conductive. I wouldn't recommend you go down the liquid metal/conductive thermal paste if you have such heatsink.

    Sorry to hear that you're having thermal issues.

    Has the laptop always done this, or did it start to overheat recently? If it started recently, was there an event that also happened around the same time?

    Based on the pictures you included, hot air should be coming out of both the rear and the side of the laptop. If air is somehow being sucked through the rear and side, and blown out of the bottom, then yes, you have some sort of fan polarity issue. With the fans at high speed, can you tell us where air is exiting the laptop?

    At those temperatures, the air exiting the laptop should be hotter than hell, and you should be able to feel more than a 'little' bit of air flowing.

    What is the ambient temperature of the room the laptop is in?

    With the information you've provided, I am guessing that the fans are not spinning up to full speed. At full speed the fans should be annoyingly loud, and plenty of hot air should be exiting the laptop.

    If there is plenty of air exiting the laptop, but it isn't relatively hot, then heat isn't transferring to the heat sinks properly. There are only two places where heat is exchanged (other than the constant heat exchange inside of the heat pipes). One is between the CPU/GPU dies, and the other is between the heat sink fins and the air that's being pushed through by the fans.

    The answers to these questions should help us to help you.

    It's been like this since I've sent the device for repair. It had a fault keyboard which they replaced and also did thermal paste renewal. Since then it overheats. I've tried undervolting my cpu, gpu and even went as far as applying liquid metal. Still overheated like a manica. As for airflow, I mean I feel a bit air that is warm but not like I can't put my fingers near it hot. But bottom cover gets so hot that I can't even pick it up and hold the device in my hands. I can also confirm that fans are annoyingly loud so they do their job. I've ran the machine without its bottom cover on and the fans were blowing towards where the bottom cover would be.

    Repaste with good thermal paste, sounds like the repair center used cheapo toothpaste.

    If this started after they messed with it, and nothing changed even after you re-pasted it yourself, I'm wondering if they didn't screw something else up in the process.

    If the fans are running, the air is not hot (it would be at those temperatures), and the bottom is getting extremely hot, then @senso is probably right about getting some better paste and doing the job again. There's a heat transfer issue between the components and the heat sink from the sounds of it. If a new paste job with proper paste doesn't change anything, then there's a contact problem with the die(s) and heat sink. You have dual GPUs, and both of them, as well as the CPU are overheating? Another issue could be that they used thermal pads that were too thick, and the CPU and GPU dies are not contacting the heat sink properly. This is all speculation since I can't work on the machine directly.

    Also, if the bottom of the laptop is getting as hot as you say it is, I wouldn't use it under a load until you figure out what the problem with the thermals is.

    Every laptop I have owned pulled air from the bottom, forced it through the heat sinks, and exhausted it out the rear or sides. That doesn't mean yours is supposed to work that way though. One question: are there small arrows on the top or bottom of your fans that indicate which direction the air is supposed to flow? Most fans will have these arrows, and all of the fans I've seen had the arrow pointing toward the open end of the fan case.

    Something is amok here, and I am interested to see what the problem ends up being.

    I can't find ICDiamond anywhere even ebay. Would Arctic MX-2 work ok? I can get that hassle free.

    Ok, I can also get that one easily. Will report back once I get it and apply it.

    Kryonaut is pretty thick!

    Thicker than Artic-MX4..

    I have been using Artic MX-4 for 4 years already, got Kryonaut when it got out, and Kryonaut is thicker than the MX-4, both work wonderfully in laptops, Kryonaut wins over, buts its like a huge difference, good heatsink contact will make more impact than crazy thermal pastes.

    Just last weekend I lapped my GT72 CPU heatsink, re-applyed Kryonaut and it stays at 62-64ºC playing BF1 on High settings without even using the fan boost button(but I'm running a custom fan curve on EC via Svet EC editor, at 62-64ºC the fans are around 50% speed, and they make almost no noise compared to the full speed fan boost that sounds like a jet engine).
