    There is already plenty of room for airflow - there is a space between battery and back cover on most laptops, all you need is to make sure the airflow would go over the whole battery surface. You can do that by routing the air from front intakes to rear exhaust fans using "guides" such as plastic raised surfaces on the back cover and on the chassis itself, or strips of foam, similar to what you can see on the attached photo if you will look at the fans (Gigabyte uses these to prevent hot air that went through heatsink from being sucked back into fan since there is always a space between back cover and other components and Gigabyte already uses this space to let airflow also come from middle intake on the back cover):

    One thing for sure... The engineers won't add in an third fan in thin and flimsy (cost and space). The job has to be done by the Cpu and Gpu fans. If they already struggle remove heat out from nowadays notebooks (and all know they run too hot already), they need to be bigger/stronger. You can't escape from rules of physics.

    That is not true. The current fans do not "struggle" to remove the heat. They are enough to remove all the heat provided that there is enough heat conductivity between heatsink and the the CPU surface. Issue is, all manufacturers use crappy thermal paste. Fortunately it is easy to fix by users themselves, meaning the users can buy freely available thermal paste and do things like this:
    https://www.reddit.com/r/MSILaptops/comments/8hcqan/msi_gs65_tear_down_and_repaste_w_liquid_metal/
    "Received my GS65 today. Stress testing out of the box with AIDA64 results in cores hitting 93C and the fans were going wild, and the GPU hitting about 88C. I was able to under volt -.200 on the CPU Core and -.150 on the Cache. CPU temps didn't go down too much so I decided to re-paste.

    Here's a link to my album on imgur:

    Post re-paste results are 70C average during AIDA64 CPU + FPU test. Max temp is 78C from the very start of the stress test due to the fan hysteresis"

    The fans definitely won't "struggle" if you will add a few air intakes on the front of the notebook so a tiny bit of air will go over the surface of the battery. They will actually last longer if there is less air resistance due to increased air intake, especially if you will place the laptop on soft surface like your bed or cover the bottom air intakes with your legs when placing the notebook on your lap. As a bonus, you will cool SSD drives better since there will be some airflow going over them, this is important for NVME drives.

    And you have tested all notebook models out there? Bold statement. And all laptops overheating mess can be fixed with better thermal paste? Oh'well, I don't know where you get this from.

    If you have read about the overheating topic.... Many of the notebook owners have to lift up the rear end of the notebook so the fans can get enoug air. Even then it struggle to cool down their notebooks. And this even with the best thermal paste out there... "Conductonaut".

    The fans is designed around the cooling. More vents in front/added vents in front = Means better and faster fans to compensate the less cooling capacity for the core components.

    A curiosity... The M$ Tragedy

    Microsoft Surface Pro 4 catches fire
    Published on 10 September 2019 by Günter Born

    Very unfortunate thing: Just a case has come to my eyes, where a Surface Pro 4 suddenly did not want to charge, then the battery expanded and the device caught fire.

    Microsoft's marketing people recently drove a real Surface troll campaign against Apple's MacBooks (see Microsoft trumps Apple MacBooks with the Surface ... ). But in practice, the problem bear sits in Redmond and is called Surface. Since the devices are pop popping up here blog posts about real problems. A perennial problem is the battery problems with the Surfaces. Sometimes the batteries are discharged too fast and Microsoft tries to tinker away with the firmware update. Then, in-line batteries suddenly die an early death​

    Not all, but most of this can. Especially if the laptops already have plenty of airflow from existing air intakes. And vast majority of them do. Even the Dell ones, which have one of the most restricted air intakes. Here is another example:

    https://www.reddit.com/r/Dell/comments/d27wz3/repasted_my_new_dell_g7_7590_and_the_results_are/
    "So the first thing I did was do a Firestrike score right out of the box on this guy after reinstalling a fresh install of Windows 10. The results are below:

    https://imgur.com/a/bRf6ZDe

    As you can see the CPU and the GPU were pretty damn close to 100c for most of the run. In fact they both hit 100c when running the test. Play close attention to the far left of the temperature scale... the scale goes all the way up to 100... in fact the CPU and GPU pretty much started close to 100c when starting the test. Also note the Firestrike score is 12,807.

    Now here is the same test run after I re-pasted:

    https://imgur.com/a/LsJ3plO

    Now pay close attention to where the CPU and GPU STARTED from. The darker blue line is the GPU. The CPU started the test right around 70c and the GPU started from around 65c I think. The highest temp that was achieved during the test was 90c and that was for 2-3 seconds and went back down. Most of the test the temps hovered around 75 or so while the other test AVERAGED around 95c. HUGE difference! Also the Firestrike score increased by 654 points from 12,807 to 13,461 without changing anything other than the thermal compound. No overclocking or anything"

    Want to see my own experience? Unlike many armchair theorycrafters, I now have Dell G7. And unlike random YouTubers, I am allowed to do a re-paste since this is not a review sample. I posted a screenshot in another thread about 9750h CPU, which for some reason has turned to Alienware-bashing thread. When using stock thermal paste, my temps were reaching 100c in Physics test and CPU was throttling. After repasting, WITHOUT UNDERVOLTING and without doing things like removing the back cover, I got much better results. This is using conventional thermal paste, not using liquid metal:

    The point is, there is no "struggle" to remove the heat by fans in this model after repaste. And I can find more links for other models from MSI, Gigabyte, Lenovo, Dell and others, where a repaste with better paste, especially liquid metal one, fixed thermal issues. I still have warranty on this unit so I will not be doing excessive modifications like adding extra holes even for battery cooling but after warranty will expire - I might add some, just for battery and SSD cooling since they have no airflow above them.
