  Only spend 200 yuan to transform the heat dissipation of Intel MacBook Pro, let it fight for a few more years!   The MacBook Pro 2016~2019 series is really the most garbage generation of MacBook products I have ever bought. From the various card problems of the butterfly keyboard, to the overheating of the i9, and various frequency reductions, it is really hard to imagine that a laptop that costs 100,000 yuan can do so badly. Among them, the most critical thing for me is the problem of frequency reduction. I have never seen this machine run at full speed since I bought it until it was modified. The frequency is lowered to 800 MHz at every turn. It is obvious that the CPU temperature is only about 72 degrees before it starts to reduce the frequency. The Core 2 Duo MacBook Pro 2009 I bought ten years ago can run more than 100 degrees, but the MacBook Pro 2018, I really don’t I've seen it CPU over 90 degrees. Of course, I know that M1 is very fragrant, and changing to M1 can cure all diseases, but I really can't accept that this MacBook Pro is just abandoned here, so I checked it online recently, and found that foreign netizens have found a solution last year . In fact, underclocking is not an Intel problem at all! It is also mentioned that the CPU starts to reduce the frequency at 72 degrees, and 72 degrees is a low temperature for the CPU. The real problem is the VRM (Voltage Regulator Module). The VRM of the MacBook Pro 2016~2019 series will start to overheat before the CPU requires higher performance, and then there is no cooling mechanism on the VRM, so the voltage will be reduced until the VRM temperature returns to normal. Therefore, if the performance cannot improve, it is a problem of Apple's design from the beginning to the end. The Intel CPU is completely blamed... The solution is also very simple, that is, let these VRMs dissipate heat normally, so foreign netizens bought SSD cooling patches and stacked them directly on top of the VRMs. A warning should be inserted here: Modifying your MacBook Pro could void the warranty or harm the console. After modification, the CPU can run at a higher temperature without reducing the frequency, but long-term high temperature may result in reduced CPU life or other damages, please make your own evaluation before modifying. But my own mentality is: if I don’t use this garbage laptop to change it, it will be like scrap iron. After running, it will start to pant and frequency drop. It’s better to screw it up. The most difficult step should be to remove the bottom case. The bottom case of this generation is made tighter with tenons. It is recommended to watch the YouTube video to learn how to remove the bottom case.   After removing the bottom case, I cut out the SSD cooling gasket and pasted it on the VRM. I didn't know which ones it was, so I pasted it blindly. For taller chips, I stick two 1.0mm spacers, and for shorter ones, I stick 3-4, just make it high enough to conduct heat to the bottom case. Mine is a MacBook Pro 2018, and it looks different in different years. You can go online to see how other people post it, but generally it’s just a random post in the above area.
