I just recently placed a new battery and speakers into a 2015 15” MacBook Pro. To do this I had to take out the entire logic board. Obviously, the fans have to be in the correct position as you can only orientate them one way when installing them. However, cool air now seems to be flowing out of the bottom side grills, and is being sucked in from the hinge area. The airflow has somehow been reversed. I have no idea how this is possible, but it is affecting the temp of the cpu. If anyone has any recommendations on what to do, it would be greatly appreciated.

Bookarc looks great, but closing the lid means thermal problems. It's not meant to be used that way, and under full load, this probably will lead to noise and overheating. I was planning to buy a stand (since I use my MacBook Pro with external monitor and keyboard), but inadequate cooling stops me, however keeping it open all the time accumulates dust.
Here is my "Reverse V" method
- Connect all cables (video) and close the lid.
- Wake from external mouse/keyboard. This will force using only the external display.
- Open the lid to about 20-40 degrees. Internal display will remain off. The Macbook will be in a "V" like shape.
- Put it on the desktop in reversed "V" form on something soft. I recommend old polyurethane mouse pad or shaped polystyrene.

Pros
- Perfect cooling. Warm air gets up, there are no obstructions to the vents and all parts are exposed to colder air.
- Cooler means less fan noise under load.
- Takes less space than fully opened notebook.
- Better bluetooth/wifi reception because lid is not fully closed (compared to fully closed one).
- Less dust accumulation.
Cons
- You cannot use your internal IR receiver.
- Some people will not be comfortable to run their HDDs from this position (10-20 degrees vertical inclination). I think it's perfectly safe.. and I have trustworthy backup system.
- If computer sleeps, you should do the steps from 2-4 again or the internal display will be on.
- Looks kinda strange compared to the great looking vertical stands available.
