With Thermalright and Gelid two manufacturers offer independently on a special mounting plate for the AMD socket AM4, which is to prevent it, the processors can be the renovation of the cooler pull unintentionally from the receptacle. This prevents the sensitive pins from bending.
Holding frame relieves the load on the CPU, socket and circuit board
The special brackets of both manufacturers ensure that the phenomenon caused by the adhesive forces of thermal paste between the CPU and the cooler base does not cause displeasure in Ryzen CPUs during a conversion. In addition, the design prevents an Athlon or Ryzen processor from being damaged in the lower area of the contact pins when the cooler is dismantled, triggered by an uncontrolled pulling out with greater effort, in which surrounding components unintentionally collide with the pins.
The simple and practical solutions from Thermalright (SST-AMD) and Gelid (AM4 CPU Protection Bracket) in the form of metal holding frames reduce the risk of damage significantly, even for less experienced users.
The background is that the AM4 socket, as with earlier AMD recordings, is a PGA socket (Pin Grid Array) in which the pins are bare below the die carrier plate. During assembly in the base of the mainboard, the contact pins are locked in place by means of a folding mechanism using a small lever that provides contact pressure. Usually this force is enough to withstand the idiosyncratic phenomenon of dismantling the cooler, but it is not always a guarantee of success. Because some thermal pastes, when they are fresh, have considerable adhesive properties, which ensure that the CPU and cooler are held together firmly, but in return are responsible for difficulties during disassembly.
Rotation option not always possible
If the adhesive forces are too high and the approach is careless, it is not uncommon for the processor and cooler to be pulled out of the socket instead of just loosening the cooler. One solution that has been used so far is to turn the cooler slightly to avoid unnecessarily large force when pulling it off. It can then often be removed easily. However, this is often hardly possible, especially when space is limited in mini-ITX housings.
