Hello Mareo.
I have set the P1 and P2 to 150 watts in the BIOS. The whole thing is cooled with an NZXT Z 73. The CPU gets a maximum of 40 degrees warm under load. But if you have a weaker cooling system, you have to lower the P1 and P2.
There seems to be a misunderstanding. There is no longer just one TDP. Digitec specifies the maximum of several possible ones. Whether this is correct or not remains to be seen. For Intel, it is a 65W TDP CPU. However, it can be up to 154W, e.g. when using the Turbo. Provided no limits are set.
