At present, it is basically the beginning of P, which is the temperature control and speed regulation of four-pin PWR. The advantage is that the speed can be adjusted with the CPU temperature. The disadvantage is that some motherboards that don't support PRW can't be used, and it's a bit noisy to turn at full speed. There are too many batches starting with P, which is quite messy, but you are lucky to get the initial batch of 00 1-0 10. The early batch did not shrink, and the later the batch shrank more seriously.
