IFixit’s initial teardown from the iMac M1 reveals big changes from previous models
A few days after the official launch of the iMac M1, iFixit released a first teardown of the new 24-inch model, revealing many changes from previous iterations of the all-in-one desktop.
Repair specialists are tearing down a mid-range iMac M1 equipped with an 8-core processor / 8-core GPU and 8 GB of RAM. The internal components of this particular machine will be different from those of the 7-core model, as the two have different cooling systems.
Before taking the device apart, iFixit noted that the iMac “looks alarmingly like an iPad on a stand.” He also performed an x-ray scan of the iMac with Creative Electron. X-ray images show two metal plates dominating the interior, as well as the fact that the integrated antenna is no longer apple-shaped.
Almost all of the internal silicon is concentrated in two narrow horizontal bands at the top and bottom of the devices. iFixit also spotted two circular components that at first glance look like button cells.
According to iFixit, the new iMac is sealed with a “classic iMac adhesive,” which the site says is not as sticky as the adhesives used on Apple’s iPad line. Unlike previous iMacs, the new model is a single sheet of glass without a metal chin to block access to its internal components.
The iMac M1 is cooled by a pair of internal fans that blow inward through the motherboard. A heat sink also removes heat from the M1 chip with a copper heat pipe and two short heatsinks. Additionally, iFixit notes that the internal components of the iMac M1 appear to be secured with screws instead of glue.
Compared to iMacs with Intel chips, the M1’s motherboard is the smallest yet. iFixit notes that the logic board appears to have a mysterious button with three LEDs underneath.
As mentioned earlier, iFixit is still in the process of dismantling the new 24-inch iMac. The second part of the teardown, which will arrive soon, will dive deeper into the device’s circular components, speakers, and the Touch ID sensor on the Magic Keyboard.
