How to effectively cool macbook?

Question

macbook

Problems:
- holding on your knees, the aluminum case burns ...
- over time, you will have to do "reballing"
In general, it's bad for a person and for a laptop.
What are the solutions? Simple cooler stands are not interested. MacBook case without holes. No way to blow. Some kind of cooling pad comes to mind. Or coolers on the sides through all the openings of the USB ports, thunderbolt ...
It would be ideal to cool with cold air.

Answer 1

VasG , macbook is not sucking air through the keyboard. No matter how it seems against the background of other laptops, but with Macs this is not the case. At least with aluminum Unibody.
In these cases, airvents (both the air inlet and outlet) are located on the rear end, in the gap between the case and the screen. Along the edges of this gap there are two coolers working oppositely - one sucks in, the other throws out air. I don't know if it's the same in all models, but in my MBP17'2011 the right cooler sucks in cold air, the left one throws out hot air. In MB'2006, the CPU and its radiator are on the left, but there the case is not Unibody either.
And so before, I also thought that cold air was sucked in through the keyboard. Until I dismantled the laptop when upgrading the screw and memory, and at the same time did not look there. Unlike other laptops with cooling through the clave, here the inner keyboard cover is almost all solid.
Probably it is correct in some way - excess dirt is not sucked through the clave, and the back slot is made in such a way that it is not blocked either with the lid open or closed (when working on an external monitor). When the lid is closed, the clave is accurately sealed by the rubber edge of the lid.
PS on the topic: to work on your knees at home, it makes sense to purchase a special stand. It can be passive , it can be with active cooling .
The passive one has at least a hard surface that doesn't overlap the airvents, unlike the knees and blankets that these airvents do block. Unlock the ervents - almost half the job is already done. An active stand will also cool the case additionally, and simply freshen the air near the laptop so that the warm ejected back does not get into the cooling airvent. Stands with coolers are usually powered from the USB port of the laptop itself.
However, this is all for the home. At home, you can keep a stand to work in a chair without a table or in bed.
When working “on the go”, you can’t carry pillows / stands with you, of course. Here I will not advise anything, except to simply try not to block this back gap between the body and the lid with your knees. Well, you can also read a bunch of different software tips & tricks to chop off something superfluous in the system, such as dealing with flash (this is for example), so that it does not load percents in the background, thus getting rid of the extra load and the extra part of the heating.
PPS vitom , you wrote in the question:
>> Simple cooler stands are not interested. MacBook case without holes. No way to blow.
Cooler pads are not designed to blow through the laptop. They create an intense heat exchange in the space around the laptop and additionally cool the case itself. Inside the laptop, the stand will not be able to overpower the regular coolers - it usually works at a reduced speed of its coolers to save power and silence.
So don't discount these stands - although not ideal, they are quite effective and cheap way to cool laptops at the moment.

Answer 2

- holding on his knees, the aluminum body burns ...

The aluminum body keeps someone on their knees and bakes. Horror movie right :)

Answer 3

He sucks air through the keyboard, so you have to go from here. Through connectors is a bad idea.
It is designed in such a way that the case is a radiator, and it needs to be cooled first of all. Here it is difficult to find an alternative to the stands. Air conditioner only :)

Answer 4

The option with knees is not discussed, everything has been said before us. I lay on the table and sometimes coolly heated the countertop. It was decided by putting an eraser under the device from the side of the lid. Worth it steadily. There is an air space between the bottom and the tabletop. If desired, you can arrange additional airflow by placing a fan on the table to the side of the laptop.
